Greater early vigour has potential for increasing biomass and grain yields of wheat crops in Mediterranean-type environments. Embryo size is an important determinant of early vigour in barley and likely to contribute to greater vigour in wheat. Little is known of the underlying genetic control for embryo size, or its genetic association with early vigour in wheat. Over 150 doubled-haploid lines...

optimization of regeneration methods in cotton is necessary to improve and successful production of transgenic cotton cultivars by tissue culture technique. this study was conducted to determine the genotypic effect on callus induction in cotton using 3 genotypes (coker349, 4-s-4 and c1211) and coker 312 selected and a study was carried out in cotton research institute of gorgan using a factori...

In the research it was examined the changes in total phenolic contents and seven major phenolic compounds (gallic acids, +(−) catechin, catechol, Chlorogenic acid, o-coumaric acid, rutin and quercetin) of two litchi cultivars (Purbi and Bedana) shoot tips and fruits (for zygotic embryos) collected in different months, in order to determine their effects on the explants browning during establish...

This study was conducted to evaluate the response of almond genotypes to osmotic stress in vitro in order to screen drought tolerance. Explants subjected to polyethyleneglycol osmotic stress (0, 3.5, and 7.0% WV) on the MS medium. Concentrations of photosynthesis pigments, anthocyanins, and carothenoids were significantly reduced under osmotic stress. Under osmotic stress, leaf water content, c...

The embryo is shown at the stage when axons are starting to grow from the trigeminal ganglion (TG) to the maxillary (Mx) and mandibuSelected Reading lar (Md) processes. The collagen gel coculture paradigm is shown in which directed axonal growth is observed from the trigeminal Buchman, V.L., and Davies, A.M. (1993). Development 118, 989– ganglion to explants of its targets but not to explants o...

persian shallot, also called leek (allium ampeloprasum), is a monocotyledon plant of the lily family (liliaceae). it belongs to the genus allium, has a characteristic taste and morphological features, and is considered as one of the oniony vegetables. this research was conducted with the purpose of obtaining optimal conditions for tissue culture of persian shallot and of comparing calli and lea...
