Streszczenie:

A ground-penetrating radar (GPR) technology was developed to study the process of water drainage in sand layers with an insignificant concentration of dusty and clayey particles when moistened from above. The technology includes a method of calibration of the GPR equipment, algorithms for processing the GPR information, and their software implementation. The technology was used to process the results of laboratory GPR measurements obtained during draining of water through sand layers from different quarries for 100 h. The absolute values and the changes in the refractive index and specific con

Studies were carried out with neem stones to trace the influence of moist storage on storability of stones at ambient conditions. The study expressed that sand medium moistened to 10% level with 10 per cent Jalshakthi maintained the higher germination (46%) and vigour index value (992) upto six months. The seed also recorded the lowest EC value (0.607) at the same period of evaluation.

Haloxylon ammodendron (C.A. Mey) Bunge (Chenopodiaceae) is a shrub occurring on desert sand dunes in China. Seedling emergence and seedling survival were investigated by sowing seeds at different depths (0, 2.5, 5.0 or 10 mm) in fine or coarse sand in pots irrigated under different regimes. Seed burial in sand was required for seedling establishment of this species. Seedling emergence depended greatly on seed burial depth, sand type, and irrigation regime; this appeared to be due to (1) seeds or seedlings suffering from oxygen or moisture deficiency depending on the air : moisture ratio in san

Sclerotinia minor is a major pathogen of peanut in North Carolina, Virginia, Oklahoma, and Texas. Partial resistance to S. minor has been reported based on field screening, but field performance is not always correlated with laboratory or greenhouse evaluations of resistance. More efficient screening methods and better understanding of the mechanisms contributing to Sclerotinia blight resistance are needed, and a detached leaf assay was developed and evaluated. Detached leaflets of 12 greenhouse-grown peanut lines were inoculated on the adaxial surface with a 4-mm-diameter mycelial plug of a s

Safflower (Carthamus tinctorius L.) is a crop with wide commercial potential, due to the broad adaptability of cultivation and use conditions, but commercial initiatives are deficient. This scenario extends to academic research, which also focuses little on understanding the involved processes from the germination of its seeds to the correct management of adult plants. In this context, the current study seeks to identify the primary metabolites stored in the safflower seed and to evaluate how the mobilization of these reserves occurs during seed germination and seedling establishment.

Cocoa production (Theobroma cacao L.) is essential globally and constitutes one of the leading export products for Colombia. Understanding the limitations faced by this crop in Latin American countries, it is required, among other aspects, to contribute to strengthening the first link in the production chain through efficient propagation methods and genetic improvement. Knowing that somatic embryogenesis is an alternative to conventional propagation and constitutes an obligatory step in a breeding platform, the objective of this work was to establish a somatic embryogenesis protocol until the

During 1994, damping-off of wild rice (Zizania palustris L.) in a single field in eastern Shasta County, CA resulted in near total stand failure. Since then, the disease was observed in at least 11 other fields with varying levels of stand loss. In all cases, the affected wild rice was grown as a volunteer crop following one or more years of wild rice production. Symptoms included a dark red discoloration and necrosis of the primary root followed by seedling death. When the red discoloration was limited to secondary roots, the plants often survived.

Syzygium malaccense belonging to the large family of Myrtaceae produces medicinal plant parts and edible fruits which contain high nutritional values and antioxidants. However, the limited occurrence of this fruit species within Malaysia has hindered its commercialization potential. Large-scale planting is necessary to promote this indigenous fruit. A timely supply of sufficient planting materials is needed for this purpose. To date, this tree species is mainly propagated by seeds while stem cutting and grafting techniques are less successful.

Spent mushroom substrate (SMS) is used by the turf industry in the northeastern United States for soil improvement. When tilled into soil at high rates, some turfgrass managers claim that SMS inhibits turf seed germination. The authors’ objectives were 1) to determine whether fresh SMS inhibits turf seed germination and, if so, which species are most adversely affected; 2) to evaluate whether any inhibition incited by SMS is the result of osmotic effects or toxicity of compounds in SMS extracts; 3) to determine whether any negative effect of SMS on germination can be eliminated by leaching the
