this research was conducted in order to evaluate genetic diversity, and screening the tolerant genotypes of sugar beet subjected to continuous and severe water stress in the experimental farm of sugar beet seed institute (sbsi) in karaj in 2008. the experimental design was a randomized complete block with 6 replications. fifteen o-types which were tolerant to drought plus 5 (check) genotypes we...

An ontogenetic study of canavanine formation in the fruit of jack bean, Canavalia ensiformis (L.) DC. was conducted. Evidence was presented to show that the ovary wall is the reservoir for seed canavanine. The testa possesses sufficient canavanine to account for the continued elevation in seed canavanine after the pod senesces. The seed canavanine concentration is not constant inasmuch as the c...

the study was conducted to evaluate the effect of seed priming on root growth of two barley cultivars (hordeum vulgare l.) under salinity stress was performed in phytogel. the treatments included two cultivars of barely (yusuf and maquie), levels of seed priming (control, hydro-priming and priming with 4.35 g l-1 of urea) and four levels of nacl salinity stress (0, 0.2, 0.3 m). the experiment w...

The interactive effects of asexual Epichloë (formerly known as Neotyphodium) endophytes isolated from Hordeum brevisubulatum, Elymus tangutorum and Achnatherum inebrians, and seed-borne fungi on Elymus sibiricus seeds, were determined by an in vitro study using supernatants from liquid cultures of the endophyte strains. In an 8 week greenhouse study, the effects on the seedlings growth was meas...

When reciprocal crosses are made between different pea genotypes, there is a strong maternal influence on mature seed size of the reciprocal hybrids, i.e. their dry weights are similar to that of seeds obtained from their maternal parents. Reciprocal crosses between pea varieties having very different mature seed sizes were used to investigate how the maternal genotype controls seed development...

Effects of silver nanoparticles on plant growth parameters such as Root length, fresh weight, Dry weight, Speed of germination and % Germination contents of economic important pulses, Fenugreek (Trigonella foenum-graecum); was probed in the present research. The study was carried out in a randomized block design with three replications. Five levels of silver nanoparticles (0, 10, 20, 30 and 40 ...

This is the first record of Acanthoscelides schrankiae Horn. feeding in seeds of Mimosa bimucronata (DC.) Kuntze. We investigated the pattern of oviposition and seed exploitation by A. schrankiae, and the distribution of mature fruits and seed predation in the inflorescences. We also compared the percentage of predated seeds, the total dry weight of fruits and non-predated seeds, the percentage...

background: fenugreek (trigonella foenum - graecum l.) is an annual medicinal plant belongs to the legume family and has anti-diabetic, anti-fertility, anticancer, anti-microbial, anti-parasitic and hypocholesterolaemic effects. objective: evaluation of growth and trigonelline /mucilage content in fenugreek under application of plant growth regulators (pgr). methods: the experiment was conducte...
