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, ...

The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

This work evaluated the effect of seed size and morphology on the development and biomass of durum wheat seedlings. Three different seed-grading sizes selected by sieving were used in glasshouse experiments, and a set of three developmental and 23 biomass-related indices were measured on eight genotypes, at two moisture levels. The influence of seed size on seedling development was studied at h...

Andrographis paniculata Nees is traditionally known as Kalmegh, Allelopathic effect of Kalmegh was examined on seed germination and seedling growth of four (Sonalika, VL-914, Euguanda-6 and Mond’s Aids) wheat genotype, the aqueous leaf extracts reduced seed germination and seedling growth of wheat. On the basis of value of per cent reduction in seed germination, germination relative index and v...
