Simulation of dry matter accumulation and the distribution of crop growth is an important means of predicting yield. In this study, a variety of cultivars of the processing tomato (Lycopersicon esculentum Mill.), sowing dates and densities were tested. By analyzing the quantitative relationships between growth and physiological development time (PDT) based on a knowledge model, dry matter parti...

Partitioning of dry matter (DM) in sugarcane is of interest for two fundamental reasons. Firstly sugar production depends directly on partitioning of biomass to the stalk and then to sucrose stored in the stalk. Secondly, various DM components of the stalk and particularly sucrose concentration are used to calculate the value of cane consignments delivered to the mill (Berding, 1997). The value...

Two pot experiments and one field experiment were conducted on sugarcane to assess the effects of treatments expected to change total carbon assimilation on the partitioning of assimilate. In the first experiment pots of cultivars CP and N14 were arranged to simulate normal field spacing. At 5 months, plants were partially defoliated or left intact. In the subsequent four months, defoliation re...

The effect of photoperiod and growing degree days (GDD) on dry matter and dry matter partitioning in Jerusalem artichoke was investigated during 2008-09 and 2009-10. Three Jerusalem artichoke genotypes (CN-52867, JA-89 and HEL-65) were planted in 15 day-intervals between with thirteen different dates (September 20 to March 20) atKhon Kaen University,Thailand. Jerusalem artichoke genotypes ...

The experiment was conducted to investigate potential causes of grain sterility in widely cultivated rice variety in Malaysia, MR219 and its two mutant lines (RM311 and RM109) by examining the source-sink relations. RM311 produced increased dry matter yield both at heading and maturity and also showed higher grain yield with greater proportion of grain sterility than the other two genotypes (RM...

Soybeans (Glycine max L. Merr. cv Tracy and Ransom) were grown under N(2)-dependent or NO(3) (-)-supplied conditions, and the partitioning of photosynthate and dry matter was characterized. Although no treatment effects on photosynthetic rates were observed, NO(3) (-)-supplied plants in both cultivars had lower starch accumulation rates than N(2)-dependent plants. Leaf extracts of NO(3) (-)-sup...

The objectives of this work were to determine the effect of nodulation on dry matter, reduced-N, and phosphorus accumulation and partitioning in above-ground vegetative parts and pods of field-grown soybean (Glycine max [L.] Merr. cv Harosoy).From comparison of nodulated and nonnodulated isolines, it was estimated that nodulated plants attained 81 and 71% of total-plant (above ground) N from up...
