this study was conducted to investigate the effects of planting date, foliar application of benomyl fungicide and potassium silicate in improving the quality of soybean (cv. williams) seed in gorgan during 2011 and 2012. in the first year (2011), the experimental treatments were including planting dates (april 20, may 13, june 3, june 29 and july 22) and foliar application of benomyl fungicide ...

Canola yield production is driven by the balance between source (leaves) and sink (pods seeds) activity during reproductive period of a crop. However, previous literature has not reported impact source-sink limitations under different nitrogen (N) supplies, its effect on seed filling. Therefore, objectives this study were to 1) explore manipulations filling main parameters: duration rate; 2) un...

It has been proposed that abscisic acid (ABA) may stimulate sucrose transport into filling seeds of legumes, potentially regulating seed growth rate. The objective of this study was to determine whether the rate of dry matter accumulation in seeds of soybeans (Glycine max L.) is correlated with the endogenous levels of ABA and sucrose in those sinks. The levels of ABA and sucrose in seed tissue...

In annual forage legumes such as the common vetch (Vicia sativa L.), in which the pods represent a substantial proportion of the total biomass, the optimum harvesting stage may not adjust to the classical model of decreasing nutritive value after flowering. The effect of harvest time on the yield of the main chemical components of common vetch was evaluated under field conditions typical of the...

in order to study the effect of temperature and photoperiod (pp) on development rate of different vegetative and reproductive stages of canola, an experiment was conducted at agricultural research station of gonbad during 2005-2007. the experiment was a randomized complete block design arranged in a split-plot in two conditions, for example supplemental irrigation and rainfed. there were differ...

Two field and laboratory experiments were conducted to investigate the effects of superabsorbent polymer (SAP) and irrigation management on seed and essential oil yields of Cumin, as well as the impact of water quality on water holding capacity of SAP. Salinity had a negative effect on the amount of water absorbed by SAP (335 and 59 g H2O per g SAP, for distilled water and solution of 0.5% NaCl...

in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...

The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...
