Genetic Factors and in Vitro Manipulations Influence Seed Dormancy in Cucumber
Seed lots with the genetic background of ‘Baroda’ and ‘Marketer’ cucumber (Cucumis sativus L.) containing all possible combinations (DF Df, Dfdf, dfdf) of df (which increases dormancy) and Df (wild type) were used. Dormancy was not solely due to the genotype dfdf and clear effects of genetic background were apparent. The df allele in the homozygous state induced a strong dormancy in ‘Baroda’, b...

according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
15 صفحه اولA STUDY ON SEED GERMINATION OF AVENA LUDOVICIANA AND THE EFFECTIVE FACTORS IN SEED DORMANCY BREAKING
Wild oat has two seeds in a spikelet that they have different physiological behavior in regard of seed germiantion. The upper seed of spikelet is smaller and has deeper dormancy than the lower seed. The range of temperature for germination is 5˚C to 25 ˚C and optimal temperature is 15˚C. Both kinds of seeds showed the more germination rate in low temperatures so that 5 and 10˚C are better...

تجارت الکترونیکی شیوه اجرای مسئولیتها، تقابل با مشتریان و امور معمول عملیاتی در شرکتها را تغییر داده است. تجارت الکترونیکی در عمل تنها خرید و فروش کالاها را از طریق ابزار الکترونیک نمی باشد، بلکه تمام فعالیتهای لازم جهت انجام فرایند فروش را نیز در بر میگیرد. در اواخر دهه 1990 بسیاری از شرکتها فعالیتهای خود را به منظور دستیابی به مشتریان جدید و یا ارائه فرصتهای جدید به مشتریان موجود گسترش دادند...
A study on genetic aspects of seed dormancy
Changes in seed dormancy were selected during the domestication of crop plants from wild-plant species, because some features of dormancy that provide ecological advantages presented agronomic disadvantages within a farmed system. Seed dormancy varies widely among seed batches, even for seeds of the same genotype, indicating large environmental influences. For genetic studies, it is essential t...
