Abstract:

The experiment was conducted at the Agronomy research field of Bangladesh Agricultural University, Mymensingh from July to December 2013 to find out the effect of seedling age and storage duration on growth and yield of wet season rice. The experiment comprised of four ages of seedling (25, 30, 35 and 40-d-old) and four storage durations (0, 1, 2 and 3-days) of uprooted seedlings. Rice var. BRRI dhan52 was used as a test variety. The experiment was laid out in a split-plot design with 3 replications placing seedling age in the main plot and storage duration in the sub- plot. The effect of age and storage -duration of seedling, and their interaction were significant on growth parameters (shoot height, root length, number of tillers hill-1, leaf area index and crop growth rate), grain yield and straw yield. The growth parameters and yield exhibited a trend of decrease with the increase in seedling age and storage duration. All the growth parameters and yield showed highest value in the younger seedlings of 25-d-old with 0-day storage duration of uprooted seedlings while the lowest in the older seedlings of 40-d-old with 3-days of storage duration. The var.BRRI dhan52 produced the highest LAI (8.23), CGR (7.33 mg day-1 hill-1) and biomass (26.87 g) at 60, 45 and 60 days after transplanting. Grain yield reduced by 13, 19 and 37% of 30, 35 and 40-d-old seedlings, respectively compared to 25-d-old seedlings. In case of seedling storage, grain yield reduced by 5, 14 and 31% of 1, 2 and 3-d storage, respectively compared to 0-d storage. For optimum growth and yield of wet season rice, 25-d-old seedlings may be stored up to 1-day after uprooting taking into account the possible delay in transporting seedlings to the flood affected area from the nearby districts.Bangladesh Agron.

Abstract:

Soybean seed is classified as “poor storer” as it loses viability under warm and humid conditions and is invaded by storage fungi. The seed of soybean variety PS 1347, obtained from Breeder Seed Production Centre, G. B. Pant University of Agriculture and Technology, Pantnagar was used for storage study. Root length (cm), shoot length (cm), seedling fresh weight (g) and seedling dry weight (g) decreases with the increase in seed storage periods. Out of all chemical treatments, Flowable thiram @ 2.4 ml/kg (T2) and Polymer + vitavax 200 @ 2g/kg seed (T5) were found effective to maintain Seedling root length, shoot length, seedling fresh weight and seedling dry weight by producing vigorous seedlings. Seeds stored in cloth bags exhibited higher seed infection than in seed stored in polythene bags, irrespective of seed treatment and period of storage. Treatment T4 (Vitavax 200 @ 2 g/kg seed)and T5(Polymer + vitavax 200 @ 2 g/kg seed) exhibited minimum percent seed infection of Aspergillus flavus. Cloth bag was not found safe for longer storage of soybean seeds under ambient storage at Pantnagar.

Abstract:

An experiment was conducted at Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during April 2013 to June 2013 to study the effect of three storage containers (tin container, polythene bag and cloth bag); and five storage periods (0, 15, 30, 45, and 60 days) on the seed quality of soybean. The experiment was laid out in Completely Randomized Design (CRD) with four replications. The soybean seeds stored in tin container showed maximum germination capacity with high germination index, highest seedling growth, seedling dry weight per plant and vigour index. The seeds stored in cloth bag had the lowest seed quality during the testing period. The highest 1000-seed weight, moisture content, electrical conductivity, abnormal seedlings and number of dead seeds were recorded in cloth bag; where the equivalent lowest values were recorded in tin container. The moisture content, 1000-seed weight, electrical conductivity, number of abnormal seedlings and dead seeds were increased with the longer period of storage. In addition, germination index, seedling growth, dry weight per plant of soybean seedling, and vigor index decreased with the increase in storage period. Among the three containers, tin container was the best and the cloth bag was the worst storage container for soybean seed storage for long period.

Abstract:

This study aimed at evaluating efficiency of different tests to assess cotton seed vigor during storage, including the SVIS® software. Thereby, five cotton seed lots (cv. BRS 293) were stored under controlled environmental conditions of low temperature and relative humidity (10 ºC; 30% RH), and under non-controlled laboratory environmental conditions, for eight months. Evaluations of germination, first germination count, cool germination, accelerated aging test traditional and with saturated salt, field seedling emergence and seedling imaging automated analysis - SVIS® were performed before and after every two storage months. It was concluded that the cool germination, accelerated aging (traditional and with saturated salt), field seedling emergence and seedlings length (SVIS®) are adequate parameters for assessing vigor of cotton seeds during storage, and that both accelerated aging and SVIS® (vigor index and seedlings length) present enough sensitivity to identify changes on seed vigor during storage.

Abstract:

Seedling emergence and growth traits of three rare and threatened tree species in the Mariana Islands were studied within a range of incident light levels and up to 9 months of seed storage. Seedling emergence percentage and velocity were maximized in moderate shade for Elaeocarpus joga Merr., deep shade for Serianthes nelsonii Merr., and full sunlight for Tabernaemontana rotensis (Kaneh.) P.T. Li. Seedling height was increased by shade for E. joga and S. nelsonii. Height of T. rotensis seedlings was not influenced by incident light from 25% to 100%. Nine months of seed storage at ambient temperature did not influence emergence percentage of E. joga or S. nelsonii seeds. In contrast, seeds of T. rotensis began declining in seedling emergence percentage between 2 and 3 months of storage, and seedling emergence was nil by 4 months. This study represents the first experimental approach to determining the influences of light and storage on seed and seedling behavior for any rare and threatened taxa from the Mariana Islands. Our findings that revealed highly contrasting responses among the species provide a valuable start to building the knowledge base needed to respond to formal recovery or conservation plans by defining horticultural protocols for managing a conservation nursery.

Abstract:

Root damage is a principal cause of poor seedling quality. Currently, the most widely used seedling-quality test measures a seedling's ability to initiate and elongate roots in a favorable environment; however, this test requires a lengthy response period and tedious, time-consuming measurements. Alternatively, the respiration rate of roots could be measured much more quickly and easily. Results of this study, which examined whether root respiration could successfully predict the survival and growth of potted Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) seedlings in a growth room, indicated that respiration may help assess root damage caused by desiccation but not that caused by freezing, hot storage, or rapid heating.

Abstract:

Abstract Root growth potential (RGP), and first-year field survival and growth of shortleaf pine (Pinus echinata Mill.) seedlings were significantly affected by lift date, storage, and family. Seedlings lifted in December and January showed highest RGP, survival, and growth. Storage for 28 daysalways reduced survival and growth, and the effect was greatest for late-lifted seedlings. However, for late planting, the difference in performance between freshly lifted seedlings and earlier lifted and stored seedlings may be small. Large family differences existed for seasonal changesin RGP and survival, suggesting separate management by family may be beneficial. The presence of a terminal bud and secondary needles showed little value in predicting seedling performance, whereas RGP and number of primary lateral roots were strongly correlated with seedling survival.

Abstract:

One-year-old Scots pine (Pinussylvestris L.) and 2-year-old Norway spruce (Piceaabies (L.) Karst.) seedlings were lifted and stored under an array of conditions to test infrared thermography as a means of determining seedling viability. After winter storage, temperature was measured on each seedling with an infrared thermovision scanner (3–5 μm) in an environment favoring transpiration (vapor pressure deficit of the ambient air 1.6–2.9 kPa, photosynthetic photon flux density 1500 μmol•m−2•s−1). Thereafter the seedlings were planted in the field. Visual signs of damage were assessed and annual height increments were measured after one and two growing seasons. Significant positive correlations were found between seedling temperature and degree of damage. The warmest seedlings had a lower survival rate as a group when compared with the remaining seedlings. There were significant negative correlations between seedling temperature and annual height increment in the first growing season.

Abstract:

Abstract Seedling emergence is the main propagation method of forest species. Thus, we aimed to evaluate emergence aspects of the tree legume Clathrotropis brunnea Amshoff (sapán or blackheart sapán), a Fabaceae of high economic value endemic to the Colombian rainforest. We characterized the biometry of legumes and seeds and assessed seedling emergence in three experiments: (1) effect of fruit color and substrate, (2) seed conservation in storage, and (3) presoaking and seed position. Our results showed that seeds of green-yellow fruits have greater length and weight and a water content of up to 53%. Seedling emergence did not differ between green-yellow and dark-brown fruits but did differ with substrate type; nearly 80% of seedlings emerged in the sand substrate (S1), but only 62% emerged in the mixed substrate (S3). Fresh sapán seeds are nondormant, showing a recalcitrant behavior in which seedling emergence decreased after storage in all tested conditions. Both seed-sowing positions allowed an emergence of &gt;80% with a small benefit of the hilum downward, regardless of presoaking treatments. However, these differences did not affect seedling height or biomass after emergence. Our results provide basic knowledge on production of tropical seedlings, seeking species conservation, and use in restoration projects.

Abstract:

The effects of storage duration (0, 2, 4, 6, 8, and 10 days), sterilization with sodium hypochlorite (0, 5, 10, 15, and 20%), and weaning media on seedling characteristics and dry matter content in Musa balbisiana seedlings were studied. The experiment was factorial in a completely randomized design with five replicates. The result indicates that increase in NaOCl concentration and number of days in storage significantly (P=0.5) increased the period of seedling emergence. Also, soaking in NaOCl for 20 min had significant effect on average seedling emergence at 15 and 20% concentrations, compared to 10 min soaking at the same concentrations. The combined effects of storage duration and sterilization resulted in a decrease in the duration of seedling emergence. Seeds previously sterilized with either water or NaOCl had no significant effect on seedling growth, leaf and corm dry weight, but affected almost all the dry matter traits. A mixture of poultry manure, top soil, and river sand as weaning media gave better seedling growth and increased dry matter characteristics. We conclude that M. balbisiana seeds require after-ripening treatment to enhance germination, sterilizing seeds with 5% NaOCl for 10 min and air-drying under ambient condition for 2–6 days were found most appropriate, and a mixture of poultry manure, top soil, and river sand is recommended as weaning medium for growth and dry matter composition in M. balbisiana seeds.

Abstract:

Vegetable grafting confers soil-borne disease resistance through the use of selected rootstocks. Additional costs associated with grafted vegetable seedling propagation limit grower access to this technology. The use of low temperature storage in grafted seedling production reduces labor costs and allows propagators to meet the seasonal and narrow-window demand of growers. For the first part of the experiment 22 genotypes of Solanaceae or Cucurbitaceae seedlings were evaluated in low temperature storage conditions (5 or 12°C). Seedling performance was better in 12°C storage than in 5°C storage. For the second part of the experiment watermelon, the most low-temperature sensitive species found in our first study, was grafted onto two different commercial rootstocks or on to other watermelon seedlings and stored at 12°C for two and four weeks. Both 'Strong Tosa' and 'Emphasis' rootstocks conferred chilling tolerance during storage to watermelon scions, allowing storage of grafted plants for two weeks.

Abstract:

Root growth potential (RGP), the ability of a transplanted seedling to rapidly elongate existing roots and initiate new roots, is used as an indicator of seedling physiological quality. Three separate experiments were conducted on loblolly pine RGP during 1983-84 and 1984-85 using 1-0 nursery-grown seedlings. In the first study, seedlings were hand-lifted from September to April at 17-day intervals in 1983-84 and 7-day intervals in 1984-85. The RGP variation over time was related to environmental and seedling phenological changes. In addition, the new root systems were morphologically described. In the second study, changes in loblolly pine seedlings following different lift-date X cold storage duration treatments were described. These changes were compared to the RGP, shoot activity, and new root system morphology of fresh-lifted seedlings. Genetic variation in RGP on different lift-dates was quantified in the third study. Variation patterns over time among 14 half-sib loblolly pine families hand-lifted at one-month intervals were examined. Root growth potential was low in the autumn until the cessation of shoot activity. Seedlings stored poorly if put in cold storage during this time, or prior to the accumulation of at least 400 chilling hours. Seedling RGP increased in the early-winter to a late-February peak, and then decreased when spring shoot elongation occurred during the RGP tests. Similar trends over time were noted with seedlings removed from cold storage during these times. The RGP pattern over time was consistent among years and among the half-sib families, although there were some minor differences among half-sib families in the rate of increase to, and decrease from, the late-winter peak. Most new roots resulted from elongation of existing roots rather than initiation of new roots regardless of lift-date; however, when seedling metabolism was high (early autumn and late-winter) both root initiation and elongation of existing roots contributed to the new root system. In addition, the morphology of root systems of cold-stored seedlings was similar to fresh-lifted seedlings. Differences in numbers and lengths of new roots among half-sib families were due to the differential ability to produce new roots through both root initiation and elongation.<br>Ph.

Abstract:

Published Article<br>A study involving two incubation experiments and a germination experiment in sandy soil was conducted to determine the influence of Multiplied Effective Micro-organisms (M-EM) that were exposed to different levels of irradiation and temperature fluctuation as well as prolonged storage, on the germination and seedling vigour of maize, sorghum and sunflower. Irrespective of poor handling and/or prolonged storage of M-EM, seed treatment with M-EM improved germination under optimal conditions for all crops compared to the control. Increased planting depths and cold stress were used to create conditions where seed treatment with M-EM may improve germination and seedling growth. Seed treatment with M-EM significantly improved germination and seedling vigour of the stress-tolerant maize cultivar following cold stress. Similar improved seedling vigour results were observed for the stress-tolerant sunflower cultivar at increased planting depth. It was concluded that the beneficial influence of M-EM as a seed treatment was remarkable, even after exposure of M-EM to unfavourable environmental conditions and prolonged storage before application. Further research under field conditions and in different cultivation systems are required before the large scale application of M-EM as seed treatment can be recommended.

The evaluation of the spray system was followed by moisture content determination, weight of 1000 seeds and coverage. Also field emergence was evaluated. The seed quality evaluations were followed by germination, vigor, dry matter of plants and seed health. The seeds were storage for six months and evaluations were done every 60 days. The results shows that soybean seed moisture content was 1% lower with the treatment; the field emergence and weight of 1000 seeds were no affected by treatment; when the change of product and/or seed the equipment should regulated for a coating good. The applied of polymer improve seed coating. The application of amino acid isolate improve the performance of the seeds; the use of amino acid combined with fungicide, insecticide and polymer do not improve the seed quality; the use of polymer fungicide + insecticide + polymer improve leaf area, dry mass of root and of part aerial of the plant compare with control in storage seed for four months after treatment.<br>Com o objetivo de avaliar o tratamento e o recobrimento de sementes de soja em um equipamento com sistema de aspersão da marca Grazmec Spray System® foi realizado um conjunto de experimentos na Faculdade de Agronomia Eliseu Maciel (FAEM) da Universidade Federal de Pelotas, campus do Capão do Leão.

Para avaliar o sistema de aspersão foi realizada a avaliações de grau de umidade, emergência em campo, peso de 1000 sementes e cobertura das sementes. Para a determinação da eficiência dos tratamentos foram realizadas avaliações de germinação, vigor, massa seca de plantas, desempenho inicial de plantas e sanidade de sementes. Após tratadas, as sementes foram armazenadas por seis meses e avaliadas a cada 60 dias. Os resultados demonstraram que o aumento no grau de umidade das sementes de soja tratadas e/ou recobertas com o equipamento de sistema de aspersão foi inferior a 1%. A emergência de plântulas e o peso de 1000 sementes não foram afetados pelo tratamento e/ou recobrimento realizado com o sistema de aspersão. Para que o recobrimento seja eficaz o equipamento deve ser regulado a cada mudança de produto e/ou semente. O uso de polímero melhora o recobrimento das sementes. A aplicação do aminoácido isolado melhora a germinação das sementes. A combinação de aminoácido com fungicida, inseticida e polímero não melhora o desempenho das sementes. A aplicação de fungicida + inseticida + polímero aumenta a área foliar, massa seca de raiz e de parte aérea das plantas quando comparada com a sem tratamento em sementes armazenadas por 4 meses após o tratamento.

This forces the nurseryman to acquire a much larger seeds than really necessary. With the adoption of standards for the quality of seed, the minimum parameters established 70% viability being suggested for such confirmation the tetrazolium test, according Rules for Seed Analysis (RSA) and/or a practical test done from the visual analysis of the seed endosperm color named in this work of "visual test". Despite tetrazolium test be scientifically based, its realization is made improbable by many financial and temporal reasons. Thus, the visual test points as a low-cost alternative, high reliability and immediate result, since both tests are considered trusted, but only the test tetrazolium test is recognized. The subject proposed to verify the credibility of the "visual test" legitimizing or not its use in the field. The field is composed of rubber seed, formed with the adult clone GT1. The seeds were homogenised and stored on two conditions: braided polypropylene bags and transparent plastic bags with minimum thickness of 0.02 mm microdrill at top. In each bag, in three treatments were placed ten kilograms of seed and these were stored in natural conditions of temperature and humidity (25° C ± 5 °C). Was pulled randomly a bag of seeds of rubber tree of each storage type, to zero and fourteen days of storing lots. The tests: visual, sprouting in sand and tetrazolium, besides the determination of the degree of moisture. Tetrazolium and visual tests were highly correlated, and the visual test results before had as the best way to analyze the seeds, for its significant correlation in General with the tetrazolium test, and simplicity in its execution and instant result, which gives good lot projection nurseryman to be acquired by him.<br>A produção de mudas de seringueira (Hevea brasiliensis) em viveiro, é limitada pelo curto período de produção, queda e coleta das sementes, que possuem uma rápida perda do seu poder germinativo e nenhuma garantia da sua viabilidade. Isto obriga o viveirista a adquirir uma quantidade de sementes maior do que aquela realmente necessária. Com a aprovação de normas para o padrão de qualidade de semente, se estabeleceram parâmetros mínimos de 70% de viabilidade sendo sugerido para tal confirmação o teste de tetrazólio, segundo as Regras para Análise de Sementes (RAS) e, ou, um teste prático feito a partir da análise visual da cor do endosperma da semente nomeado no presente trabalho de “teste visual”. Apesar do teste de tetrazólio ser embasado cientificamente, sua realização é inviabilizada por diversos motivos de ordem financeira e temporal. Sendo assim, o teste visual aponta como uma alternativa de baixo custo, alta confiabilidade e resultado imediato, já que ambos os testes são considerados confiáveis, mas apenas o teste de tetrazólio é reconhecido. Nesta pesquisa objetivou-se verificar a credibilidade do “teste visual” legitimando ou não seu uso no campo. As sementes de seringueira foram coletadas no município de Goianésia, estado de Goiás. O campo de sementes é constituido de seringal adulto, formado com o clone GT1. As sementes foram homogeneizadas e armazenadas em duas condições: sacos de polipropileno trançado e sacos plásticos transparentes com espessura mínima de 0,02 mm, microperfurados na parte superior. Em cada saco, nos dois tratamentos, foram colocados dez quilogramas de sementes e estes foram armazenados em condições naturais de temperatura e umidade (25° C ± 5 °C). Foi retirado aleatoriamente um saco de sementes de seringueira de cada tipo de armazenamento, no tempo zero e aos quatorze dias de armazenamento dos lotes de sementes coletados. Foram realizados os testes: visual, de germinação em areia e de tetrazólio, além da determinação do grau de umidade. Os testes visual e de tetrazolio foram altamente correlatos. O teste visual apresentou a melhor forma de análise das sementes, por sua significativa correlação no geral com o teste de tetrazólio, além da simplicidade em sua execução e resultado instantâneo, o que confere ao viveirista uma boa projeção do lote de sementes a serem adquiridas para a produção de mudas de seringueiras

Abstract:

Abstract The major objectives of guava breeding are aimed at improving both plant and fruit characteristics such as to develop high-yielding, high-quality dwarf cultivars with fruits of uniform shape, good size, attractive skin and pulp colour, fewer and/or soft seeds, resistant to wilt, nematodes and long storage life. Selection of superior seedlings has resulted in the development of a number of cultivars in different countries. This chapter describes the Psidium species used in breeding (Psidium cattleyanum, P. guineense, P. acutangulum, P. friedrichsthalianum, P. angulatum and P. littorale), objectives of breeding programmes, introduction and selection, inheritance pattern, interspecific hybridization, polyploidy, mutation and molecular characterization. Guava cultivars growing in different countries (Brazil, China, Egypt, India, Israel, Malaysia, Mexico, Pakistan, South Africa, Taiwan, Thailand, USA and vietnam) are also described.

Abstract:

AbstractThe fragmented forests of Taita Hills form an exceptional multi-functional socio-ecological production landscape with outstanding diversity of flora and fauna that provide ecosystem goods and services supporting human wellbeing and livelihood systems. However, these forests are threatened by illegal logging for wood products and encroachment for crop farming. A study was conducted in villages surrounding five forest fragments to establish the conservation programmes responsible for keeping these forests intact for provision of goods and services to the local communities. Semi-structured questionnaires were used to collect data from 250 respondents in 25 villages surrounding the five forest fragments. Twenty-five focus group discussions (FGDs) were held with key informants actively involved in conservation activities. Results showed that the Taita community conserves the forest fragments through management practices that integrate livelihood needs in conservation, such as butterfly farming, bee-keeping and ecotourism. Additionally, community tree nurseries have been established to produce seedlings for restoring degraded areas, and agroforestry belts have been established on the forests’ edges to provide wood products and protect the forests from encroachment. Likewise, village committees have been established to oversee conservation activities inside the village jurisdictional area. The integrated conservation and livelihood approach has reduced forest destruction, enhanced landscape connectivity for biodiversity conservation, increased incomes, enhanced capacity of the community to adapt to climate change, improved food security, enhanced carbon storage, strengthened traditional knowledge and practices, and ensured availability of clean water for the local population.

Full text

Abstract:

For the estimation of Impact of inadequate concentration of boron in seed storage proteins content in oilseed crops, a sand culture experiment was designed and all the three crops i.e. soyabean, mustard and linseed were grown under sufficient and insufficient boron treatment till maturity. Seed germination and seed storage protein concentration was determined in seeds after the harvesting of crops. Earlier oilseed crops like soyabean, mustard and linseed are cultivated for oil production but at this time these crops are reliable source of protein also and are real asset for human dietary protein. The storage protein present in seeds varies from ~10% (in cereals) to 40% (in certain legumes and oilseeds) of dry weight. Seeds contain one or more groups of proteins that are present in high amounts and that serve to provide a store of amino acids and sulfur required during germination and seedling growth. Quality of seeds is driven by the total protein content present in the form of storage reserve in seeds. There are major four types of storage proteins known as- globulins (insoluble in water), albumins (soluble in water), prolamins (soluble in alcohol) and glutelins (soluble in dilute acid and alkaline medium). Globulins and albumins are the major storage seed proteins of legumes and oilseed crops whereas prolamins and glutelins are mostly found in cereal seeds. Functionally boron is crucial micronutrient for a considerable amount of agricultural yield. Seed reserves (proteins, carbohydrates, starch, lipids) of post harvested seeds are depended on the appropriate boron supply during cropping. Boron insufficiency in oilseed crops found to be an inhibitory factor for seed vigor and seed quality. So this chapter deals with the effect of boron deprivation on seed quality in terms of germination capacity and seed storage protein reserves in the post harvested seeds of soybean, mustard and linseed.

Abstract:

Fertilizers for soil on which plants grow come in a variety of forms, such as organic, inorganic, single nutrient, double nutrient, complete fertilizer (contains N, P, and K in that order), speciality fertilizers, composts, and manures. Information about each of these forms follows. Most of the N used in fertilizers is derived from a synthetic process developed by Europeans called the “Claude-Haber process.” This process uses nitrogen gas (N2) from the atmosphere along with hydrogen gas (H2) from natural gas in a device where pressure can be increased and temperature can be raised. The reaction is accelerated using an iron catalyst and removing the product (NH3) as it is formed. The Fe catalyst is subject to poisoning from impurities, such as As, Co, P, or S. Anhydrous ammonia has the highest percentage of N and the cheapest per unit of N since no processing is involved. Anhydrous (without water) ammonia is a gas but when compressed changes to a liquid. For application to soils a pressurized tank is required with a device to inject the liquid ammonia into the soil. Upon release of pressure, the liquid changes back to a gas; however, the ammonia gas reacts with the moisture in the soil to form NH4+ that is available for plants. One problem with ammonia is that NH3 gas is toxic to seedlings and growing plants, so must be applied prior to planting. This limits its use for landscape projects. Salt solutions of aqua ammonia are obtained by dissolving ammonia gas, ammonium nitrate, or urea in water. The amount dissolved will vary the concentration of N in the final product. This can be used in landscape projects, but care must be used as this material can salt out and plug up orifices when sprayed onto a soil. There is no real difference between liquid or solid fertilizers, provided the percentage of N is the same. Ammonia Nitrate [NH4NO3] (33.5% N) Ammonium nitrate is formed by ammonia gas reacting with nitric acid: . . . NH3 + HNO3 → NH4NO3 . . . This material is hygroscopic (absorbs water from the air) and requires moisture-proof bags for storage.
