evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

background & aim: black seed or black cumin (nigella sativa l.) belongs the family ranunculaceae. black seed is one of these species, which is naturally distributed in different parts of the country. it is extensively cultivated in various regions of iran.  experimental: the experiment was achieved using randomized complete block design with three replications in the research field of islam...

During oil deposition in developing seeds of Arabidopsis, photosynthate is imported in the form of carbohydrates into the embryo and converted to triacylglycerols. To identify genes essential for this process and to investigate the molecular basis for the developmental regulation of oil accumulation, mutants producing wrinkled, incompletely filled seeds were isolated. A novel mutant locus, wrin...

Approaching switchgrass (Panicum virgatum L.) as a multifunctional energy plant, it is important to comprehensively study the composition and partitioning of organic substances in the biomass. The character of carbohydrates and lignin concentration variation was assessed in switchgrass biomass cut at two maturity stages (heading and seed filling) in the first and second harvest years. Quality c...

Two field experiments were carried out to investigate the effects of terminal drought on chickpea grown under water-limited conditions in the Mediterranean-climatic region of Western Australia. In the first experiment, five desi (small angular seeds) chickpeas and one kabuli ( large round seeds) chickpea were grown in the field with and without irrigation after flowering. In the second experime...

In order to solve problems of lower seed-filling stability and wheat seed damage mechanical shooting seed-metering device, the filling structure device was optimized. The effects movement were obtained through analysing kinematics dynamics distributor. influence factors inner diameter distributor, rotational speed distributor inclination angle window. discrete element software (DEM) used simula...

Seed growth and accumulation of storage products relies on the delivery of sucrose from the maternal to the filial tissues. The transport route is hidden inside the seed and has never been visualized in vivo. Our approach, based on high-field nuclear magnetic resonance and a custom made (13)C/(1) H double resonant coil, allows the non-invasive imaging and monitoring of sucrose allocation within...
