Imbibition during the first few hours is crucial for the success of seed germination process. The effect of water deficit after 2 and 8 hours (h) of imbibition of seeds of durum wheat was studied in terms of reserve mobilization, total sugars and proteins at 24, 48 and 72 h post treatment. Imbibition for 2 and 8 h was not enough to support normal mobilization of seed reserves and solubilization...

in order to examination of dual purpose herbicides on some wheat physiological indexes in different stages of phenology of this corp, an experiment was conducted in 1386-1387, in kordkoy, golestan province with dry farming condition. this study was performed as factorial in randomized complete block design with 2 factors and 4 replications. the first factor included the type of herbicides: shov...

A field experiment was conducted on deep vertisols of Bhopal, India to evaluate the manural potential of three organic manures: farmyard manure (FYM), poultry manure (PM), phosphocompost (PC) vis-a-vis 0%, 75% and 100% recommended dose of fertilizer-NPK and to find out the most productive cropping system at various combinations of organic manures and chemical fertilizers. The seed yield of inte...

A series of experiments were conducted in laboratory at The University of Agriculture, Peshawar to determine the optimal duration and maximal concentration of zinc (Zn) and phosphorus (P) for priming wheat seed. The seeds were soaked through a range of durations (0, 12, 18, 24, 36 and 48 h) and tested for germination as surface dry and dried to original moisture (12%). Seed soaked for 18 h resu...

Sucrose transport is the central system for the allocation of carbon resources in vascular plants. Sucrose synthase (SUS), which reversibly catalyzes sucrose synthesis and cleavage, represents a key enzyme in the control of the flow of carbon into starch biosynthesis. In the present study the genomic identification and characterization of the Sus2-2A and Sus2-2B genes coding for SUS in durum wh...

to determine ancient seed species, 3250-3450 year-old charred seeds obtained from different iranian archaeological sites were studied using scanning electron microscopy (sem) and molecular analysis. sem analysis of ancient seeds revealed that the surface of the seeds was damaged. therefore, we could not accurately identify their species. molecular analysis on ancient specimens was done on diffe...

limitations of water and nitrogen in soil usually restrict plant growth. the objective of this study was to evaluate the effects of different amounts of supplemental irrigation at different growth stages and application of different rates of nitrogen fertilizer on grain yield and water productivity of wheat cultivars. a field experiment was conducted in the agricultural research station of shah...

FRYDA, S. J., and J. D. OTTA. 1978. Epiphytic movement and survival of Pseudomonas syringae on spring wheat. Phytopathology 68:1064-1067. Field, greenhouse, and growth chamber experiments seedlings at 10 C than at 16 or 22 C. In the field, with a demonstrated that Pseudomonas syringae, the incitant of serotype VI isolate as a marker, seedborne P. syringae was bacterial leaf necrosis of wheat, m...

in order to evaluate the effect of nitrogen (n) and seeding rate and presence of rapeseed residues on yield and yield components of wheat, a field experiment was conducted in cropping year 2011- 12 at college of agriculture, shiraz university (badjgah), shiraz, iran as split-split plot arranged in randomized complete blocks design with three replications. treatment included presence and absence...

The microbial component of healthy seeds - the seed microbiome - appears to be inherited between plant generations and can dynamically influence germination, plant performance, and survival. As such, methods to optimize the seed microbiomes of major crops could have far-reaching implications for plant breeding and crop improvement to enhance agricultural food, feed, and fiber production. Here, ...
