Abstract:
SUMMARYTwo-year-old tea bushes were given NPK fertilizer on 12 November 1986 and 14CO2 on 22–23 December 1986 and 9–10 January 1987. Late-autumn fertilizer dressing stimulated photosynthate accumulation in the whole bush, especially in overwintering leaves and roots. Large amounts of photosynthates in overwintering leaves provide the nutrition required for early spring budding. Lateautumn dressing also accelerated the transport of photosynthates from leaves to roots in winter, where photosynthates, with absorbed nitrogen, synthesized more animo acids, especially theanine and phenylalanine. The re-use of photosynthates stored in the roots of the dressed bushes during shoot growth the following spring was also facilitated by late-autumn dressing. The contents of amino acids and caffeine in the shoots of dressed bushes were much higher than those in the control, whereas the content of polyphenol was lower than in the control. The results indicate that late-autumn dressing improves the quality of spring green tea.

Abstract:
Rootstocks (Piceaabies (L.) Karst.) and scions (Piceapungens Engelm.) were labelled separately during graft union development with 14CO2 and translocation of the labelled photosynthate determined qualitatively and quantitatively. Rootstock photosynthates did not cross the graft union after scion budbreak had started. Total recovery of labelled scion photosynthates in scions declined from nearly 60% to less than 10% during the 1st week after grafting, and did not increase until xylem connections were established 1-2 weeks before budbreak. Less than 2% of the recovery from the scion was found in the graft union before scion budbreak. Most of the label recovered before scion budbreak was in the needle sugar fraction. After budbreak, most of the label was recovered in elongating buds.

Abstract:
Flowering-size Nerine bowdenii bulbs were sampled from a commercial planting at 2-week intervals from 13 Aug. 1991 to 14 June 1992. They were dissected, and the following variables were recorded: 1) number and dry weight of fully sheathing leaf bases or leaves of each growth unit, 2) length and dry weight of foliage leaves, 3) fresh weight of outermost inflorescence, and 4) dry weight of daughter bulbs. Bulb organs that served as sinks and sources changed as the bulb progressed in its growth and developmental cycle. Before the new foliage provided photosynthates, growth depended on reserves deposited and stored in leaf bases during the preceding seasons. Reserves were used for the development of new leaves (foliage and bases), roots, and daughter bulb enlargement. Once the foliage became the photosynthate source, reserves were stored in old and new leaf bases. The inflorescence became the major sink when elongation of the scape initiated. Thereafter, daughter bulbs became the dominant sinks, receiving photosynthates from the senescence foliage and the reserves stored in leaf bases. The decrease in dry weight of the leaf bases was prominent in bulbs that remained in situ.

Full text
Abstract:
Carbohydrate reserves are major substrates for cold hardiness and respiration during winter and for early growth during the following season for most woody plants. In apple, carbohydrate reserve accumulation occurs mainly in late summer and autumn as temperature and photoperiod decrease. However, information on the response of reserve carbohydrate accumulation and photosynthate partitioning into sorbitol, sucrose, and starch in apple to decreasing temperature and photoperiod is limited. One-year-old `Gala' apple plants were grown in controlled environments at 26 °C and 16-h photoperiod for 50 d and then either remained in 26 °C/16 h or were subjected to a lower temperature and shorter photoperiod for 28 d that resulted in four treatments of 26 °C/16h (HT/LD), 26 °C/8h (HT/SD), 13 °C/16h (LT/LD), 13 °C/8h (LT/SD). Newly fixed 14C-photosynthates and reserve carbohydrates were analyzed in leaves, stems, and roots. Leaf photosynthesis and plant growth parameters were also examined. The LT treatments inhibited plant shoot growth and leaf initiation rates while SD treatments had little additive effect. Plants with LD treatments had greater specific leaf weight, but decreased photosynthetic rates compared to SD regimes. A decrease in temperature altered partitioning of newly fixed 14C-photosynthates into sorbitol, sucrose, and starch and carbohydrate accumulation in various plant organs. Low temperature effects were modified by photoperiod.

Full text
Abstract:
The current annual growth of foliage, branches, and stems per unit of foliar weight was approximately the same in unthinned stands of young balsam fir (Abiesbalsamea (L.) Mill.) and stands thinned 4–6 years earlier. Foliage, branches, and stems accounted for approximately 30, 30, and 40%, respectively, of aboveground growth in the thinned and unthinned stands. The allocation of photosynthates to stems was estimated by adding the carbon used for respiration to that used for growth. The proportion of photosynthetic production allocated to stems was greater in an unthinned stand than in a thinned stand. The additional proportion of net photosynthetic production allocated to stems in the unthinned stand was used for maintenance respiration. Since the photosynthetic production per unit of foliar weight of thinned stands should equal or exceed that of unthinned stands, differences in the proportion of photosynthates allocated to stems between these stands imply differences in the proportion of photosynthates allocated to other tree components. Therefore, it appears that a larger proportion of photosynthates was allocated to branch respiration and (or) roots in thinned stands than in unthinned stands.

Abstract:
Potted `Chardonnay' grapevines (Vitis vinifera L.) with either two or three shoots were grown in a greenhouse for one month and then transferred to a phytotron room, where either one or two shoots were shaded. Twenty-four days after transfer, leaves at the fifth node of either the light-adapted or shade-adapted shoot were exposed to a 2-hour pulse of 14CO2. Both light environment and number of shade shoots on the vine had a significant effect on photosynthate partitioning within the plant following a 22-hour chase. Leaves fed with 14CO2 on a light-adapted shoot translocated 26.1% and 12.7% more radioactivity to the roots and trunk, respectively, than leaves from shade-adapted shoots. Photosynthates were exported from light-adapted leaves to shade-adapted shoots (1.3% of total 14C in plant). The number of shaded shoots and the light environment of the fed leaf had a large effect on partitioning of photosynthates among ethanol-insoluble, water-soluble, and chloroform-soluble fractions within the leaf. Recovered 14C in the water-soluble fraction of the fed leaf appeared to be affected more by number of shoots than by light environment of the fed leaf. The data suggest that there is a sink effect on initial carbon partitioning patterns in grapevine leaves. Sink strength may have a greater role than light environment. A large proportion of interior leaves versus exterior leaves may be costly with respect to the carbohydrate budget of a vine.

Abstract:
The influence of fruits on export and distribution of photosynthates was studied in Vitis vinifera L. cv. Tempranillo using 14C labelling. Also, the influence of water stress was analysed in fruiting and fruitless plants of Tempranillo and fruiting plants of cv. Alfonso Lavallée. In fruitless plants of Tempranillo, reserve organs (trunk, roots and lower shoot) represented 80% of total plant dry matter (DM), and imported up to 90% of the total 14C exported from the fed leaf. Therefore, the distribution pattern of photosynthates in these plants reflected mainly the sink size. However, the presence of fruits in Tempranillo strongly stimulated 14C export and changed the distribution pattern of assimilates. Fruits imported up to 70–80% of the total 14C exported, while representing only 25% of the total plant DM. Therefore, the strength of fruits as carbon sinks was independent of sink size, and it is discussed on the basis of a water potential gradient theory. Water stress caused a significant reduction of leaf water potential, photosynthesis and stomatal conductance, but caused only a slight, non-significant, decrease of carbohydrate export from the fed leaves, and did not affect the distribution pattern of 14C except in some minor fractions in Tempranillo. The 14C distribution into different fruit components was also unaffected. In contrast, in Alfonso Lavallée water stress resulted in a highly significant reduction of export, and an altered photosynthate distribution pattern. These differences could be due to the lower water potential attained in stressed Alfonso Lavallée plants.

Abstract:
SUMMARYCommon bean (Phaseolus vulgaris L.) is the most important food legume for human consumption. Drought stress is the major abiotic stress limitation of bean yields in smallholder farming systems worldwide. The current work aimed to determine the role of enhanced photosynthate mobilization to improve adaptation to intermittent and terminal drought stress and to identify a few key adaptive traits that can be used for developing drought-resistant genotypes. Field studies were conducted over three seasons at Centro Internacional de Agricultura Tropical, Palmira, Colombia to determine genotypic differences in adaptation to intermittent (two seasons) and terminal (one season) drought stress compared with irrigated conditions. A set of 36 genotypes, including 33 common bean, two wild bean and one cowpea were evaluated using a 6 × 6 lattice design under irrigated and rainfed field conditions. Three common bean elite lines (NCB 226, SEN 56, SER 125) were identified with superior levels of adaptation to both intermittent and terminal drought stress conditions. The greater performance of these lines under drought stress was associated with their ability to remobilize photosynthate to increase grain yield based on higher values of harvest index, pod harvest index, leaf area index and canopy biomass. Two wild bean germplasm accessions (G 19902, G 24390) showed very poor adaptation to both types of drought stress. One small-seeded black line (NCB 226) was superior in combining greater values of canopy biomass with greater ability to mobilize photosynthates to grain under both types of drought stress. Two small-seeded red lines (SER 78, SER 125) seem to combine the desirable traits of enhanced mobilization of photosynthates to seed with effective use of water through canopy cooling under terminal drought stress. Pod harvest index showed significant positive association with grain yield under both types of drought stress and this trait can be used by breeders as an additional selection method to grain yield in evaluation of breeding populations for both types of drought stress.

Abstract:
Rooted single leaves of sweet potato (Ipomoea batatas L.) produce and translocate photosynthates, thus representing an ideal model for characterising the source–sink relationships and responses to various environments. A hydroponics culture study was conducted with rooted single leaves of sweet potato to determine intraspecific variation in growth, biomass partitioning, and associated physiological changes in response to variable potassium (K) supply among genotypes Ji22 (low K-use efficiency), Nan88 (high K-uptake efficiency) and Xu28 (high K-use efficiency). Potassium deficiency suppressed biomass accumulation in blades, petioles and roots in all three genotypes. Root length of diameters <0.25 mm and 0.25–0.5 mm was significantly less for K-deficient than K-sufficient roots of all genotypes, but the difference was proportionally greater in the K-inefficient genotype Ji22 than the other two genotypes. Potassium deficiency also severely inhibited net photosynthesis of blades in Nan88 and Ji22, as well reducing photosynthate translocation, increasing starch, hexose and sucrose concentrations, and decreasing K concentration in blades. The genotypes varied in photosynthesis-related responses to the K deficiency. Xu28 had greater blade K concentration and net photosynthesis as well as stable maximum quantum yield of photosystem II (FV/FM, with FV = FM – F0) under K deficiency, possibly because of a better source–sink balance and more efficient translocation of photosynthates to roots and K to blade compared with genotypes Ji22 and Nan88. Impaired phloem loading during K deficiency was associated with a decline in photosynthetic rate and decreased carbohydrate supply from blades, resulting in restricted root growth.

Abstract:
Water and photosynthate transport through plants has been studied extensively for the past three centuries. Few techniques are available that are capable of providing both physiological and anatomical information, and most are destructive in nature. We report the use of high resolution magnetic resonance microscopy (MRM) for the study of intact plant vasculature. Both two- (2-D) and three-dimensional (3-D) image acquisition protocols are employed wherein the plant vasculature can be readily distinguished from surrounding parenchymal tissue. In the 3-D image sets, the vasculature has been digitally segmented, allowing isolation of only the intact vascular architecture. The paths of water and photosynthate transport into several plant specimens have been visualized in this manner. Images of sugar beets, plants that store high concentrations of sucrose within the parenchyma, show contrast patterns between vasculature and parenchyma that are opposite to those seen in images acquired of an apple, fig, okra pod, kiwi fruit, and potato, plants that do not store high concentrations of sucrose. This suggests that transport and accumulation of photosynthates may be partially responsible for contrasts seen within images acquired of these plant specimens. Key words: transport, transpiration, sugar, MRI, magnetic resonance imaging, plants.

Abstract:
Mature field-grown apple trees were used to gain a better understanding of the influences of light and fruit on leaf physiology. Light effects on net photosynthesis (Pn), specific leaf weight (SLW), leaf N content (Weight/area) (Nw), and leaf N concentration (% dry weight) (Np) of spur leaves from two canopy locations were evaluated on four dates in 1987. Interior leaves had lower Pn, SLW, Nw, and Np than exterior leaves. In 1988 the influence of %available photosynthetic photon flux (PPF) on the same parameters was examined throughout the season. On most measurement dates both Pn and SLW increased quadratically while Nw increased linearly with increasing PPF. In both years positive linear relationships existed between Pn and Nw, SLW and Nw, and Pn and SLW.

Abstract:
Net photosynthesis (Pn) and photosynthate partitioning were compared between fruiting and deblossomed strawberry plants. Throughout a six-week fruiting cycle, Pn (leaf area basis), specific leaf weight (SLW), and chlorophyll content were determined at 7-day intervals for an early-formed leaf (old leaf) and for the most recently expanded leaf (young leaf) of fruiting and deblossomed day-neutral plants (cv. Tribute). During the fifth week of the fruiting cycle, Pn of the young leaf was higher for fruiting plants than for deblossomed plants. Pn of the old leaf was not different between treatments during any week. During weeks 4 and 5, the young leaf of the deblossomed plants had a higher SLW than that of fruiting plants; SLW of the old leaf was higher for deblossomed plants during weeks 4-6. The young leaf of the deblossomed plants had a higher chlorophyll content than that of fruiting plants during weeks 1 and 4. Chlorophyll content of the old leaf was higher for deblossomed plants during weeks 1, 2, and 4. There were no differences between treatments for stomatal conductance for CO₂ or dark respiration during any week of the fruiting cycle. In another experiment, deblossoming day-neutral strawberry plants (cv. Tribute) increased the amount of ¹⁴C translocated to the newly-emerging leaves 48 hrs after treatment with ¹⁴CO₂. During weeks 3-6 of the fruiting cycle, leaves of deblossomed plants had a greater total area, dry weight, and total non-structural carbohydrate (TNSC) content than leaves of fruiting plants. Pn on a whole-plant basis was higher for deblossomed plants than fruiting plants. This was largely due to the greater leaf area of the deblossomed plants, since total leaf area was highly correlated with Pn (whole plant basis). Pn (whole plant basis) was highly correlated with total dry weight and TNSC of plants in both treatments. Thus, deblossoming changed Pn and dry matter partitioning of strawberry plants. The additional leaf area and greater Pn rates (whole plant basis) obtained by deblossoming strawberry plants may result in increased yields during subsequent fruiting cycles.

Abstract:
Seasonal priorities for the use of current photosynthate were studied in the leaves of Betula glandulosa Michx. and Ledum groenlandicum Oeder from northern Quebec. A sequential extraction scheme was developed to separate ('14)C-labelled leaf tissues into several classes of organic compounds. Data were analysed in terms of carbon use priority (CUP) defined as the ('14)C activity in a compound category as percentage of the total activity in the leaf.
Developing leaves represented the strongest sink for current photosynthate among evergreen leaf age classes. In both species the priorities for structural components, leaf protection and metabolic components decreased while the importance of cellular lipids and storage carbohydrates increased with leaf age. The deciduous leaves had higher overall carbon use priorities for metabolic components, cellular lipids and storage carbohydrates. The priorities for structural components and leaf protection were higher in the evergreen leaves. Leaf protection was an important consideration in both species. Both B. glandulosa and L. groenlandicum leaves (1) allocated photosynthate to antiherbivore compounds when leaf succeptibility was highest, (2) used both quantitative and qualitative type defenses, and (3) reduced carbon use for quantitative type defenses during active growth.

Abstract:
During nutrient-replete growth of microalgae, new photosynthate is allocated toward three different biochemical pools: light harvesting compounds, the biosynthetic apparatus and energy storage. The mechanisms governing allocation of photosynthate between the energy storage compounds carbohydrate and lipid are not well understood. For biofuel production, it is desirable to identify conditions and algal strains that allocate maximum amounts of photosynthate to lipid. This thesis assessed the allocation of photosynthate toward the energy storage pool, and to lipid vs. carbohydrate, at two light levels and during ongoing nitrogen-starvation, for two diatoms and two chlorophytes. Nitrogen-starvation resulted in an increase in the photosynthate allocated toward energy storage, however the magnitude of change was determined by a combination of species and light level. Of the four species studied, the diatom Chaetoceros muelleri, grown in high light, accumulated lipid during N-starvation at a relatively high rate, making it a good candidate for biofuel production.

Mineral concentrations of fruits and leaves were investigated during the period of growth and development of guava “Jen-Ju Bar”. Results showed that N, P, Ca, Mg, Fe, Mn, Cu and Zn concentrations decreased with the growth of fruits. Leaf N and K concentrations also decreased, but P, Ca, Mg, Fe, Mn, Zn on the other hand increased with the increasing size of the fruits. From bloom to maturity, winter crops took about 142 days while summer crops needed relatively short period of about 98 days. Growth curve displayed a double sigmiodal pattern. “Jen-Ju Bar” tends to turn soft after harvest. This seems to be related to the Ca content in the fruits and three cultural techniques were employed to improve quality and to prevent Ca and other minerals deficiencies from happening. Regulation of leaf to fruit ratios was adopted to evaluate the Ca content and the results indicated that fruit Ca was higher in plants with 8 to 16 leaves per fruit at the time of maturation. Better fruit quality was obtained with 12 to 16 leaves per single fruit. Bagging with polyethylene in addition with white expandable polystyrene or net lining had no effect on fruit size at maturity. Neither did they affect N, P, K, Fe, Cu and Zn concentrations in fruit. By contrast, net lined bagging enhanced Ca, Mg, and Mn as well as starch content, but it contributed little to the total soluble sugar concentration. When “Jen-Ju Bar” guava scions were grafted onto 4 different stocks, mineral absorption by stock “Da-Ti” was most rapid and thus led to the accumulation of higher macro-element concentrations in leaves. Fruit soluble sugar concentration would reach the highest level whenever scion was grafted on “Jen-Ju Bar”. The starch content, however, was elevated to the highest level only when scions were grafted on “Shui-Jing” stock. No significant differences were found in leaf soluble sugar and starch in the graftage experiment. The firmness of fruit and the total soluble solids were negatively correlated with Mg whereas the ascorbic acid was positively correlated with Mg concentration. Fruit Ca and total soluble sugar had a similar trend. In leaf P and Ca concentrations were negatively correlated with total soluble solids, while Ca and ascorbic acid were found positively correlated. In the high quality”Jen-Ju Bar” fruits, N was found to be between 0.5 and 0.86%; P:0.061- 0.105%; K:1.04- 1.5 %; Ca:0.024-0.068%; Mg:0.023-0.039%. Leaf N concentration was 1.45-1.71%; P:0.111-0.149%; K:0.69-1.21%; Ca:1.49-2.81% and concentration of Mg ranged from 0.15 to 0.33 %. These figures could be used as a reference in the fertilization and management programs in producing good quality “Jen-Ju Bar” guava in the field.

Abstract:
AbstractWe targeted not only the elements we can supply to the nutrient solution but also carbon dioxide gas to visualize the fixation process and the movement of assimilated carbon in a plant. This is another highlight of our study using real-time RI imaging systems (RRIS). The interesting result was that the route of assimilated carbon was different depending on where the fixation took place. In Arabidopsis, most of the metabolites after photosynthesis were transferred to the tip of the main internode and roots when 14CO2 gas was fixed and photosynthates were produced at rosette leaves, whereas most of the metabolites moved to the tip of the branch internode and hardly moved down to the roots when 14CO2 gas was supplied to the aboveground parts of the plant other than rosette leaves. Interestingly, it was possible to visualize and trace which tissue performed the fixation of 14CO2 gas, i.e., carbon could be traced from the fixation site in tissue to tissue formation. However, especially in the case of 14C imaging, image analysis should be carefully performed because of the self-absorption of the β-rays in tissue. To image 14CO2 gas fixation in larger samples, approximately 50 cm in height, a plastic scintillator was introduced, and the assimilation process of the gas was visualized for rice and maize.
