مطالعه سیتولوژیک Hordeum bulbosum L. در ایران
گونه Hordeum bulbosum همواره به عنوان یکی از منابع آللی مفید که میتواند در اصلاح غلات زراعی استفاده شود مد نظر است. در این تحقیق، کاریوتیپ 32 نمونه جمعیتی این گونه جمعآوری شده از نقاط مختلف ایران مورد بررسی قرار گرفت. تقارن کایوتیپی جمعیتها و ارتباط آن با مناطق جغرافیایی ارزیابی شد. تمامی جمعیتهای مطالعه شده تتراپلوئید با کاریوتیپ، متقارن بودند و شاخصهای بررسی شده نشان از اتوتتراپلوئید بو...

One of the ways of haploid production is a cross between wheat and maize. Recently success has been achieved in this method, leading to the production of zygotes; these zygotes generally undergo elimination of maize chromosomes and thus lead to production of wheat haploid plant. The purpose of this study was to develop an efficient method of haploid production via maize pollination in short dur...

The significance of haploid plants as genetic and plant breeding tools has been recognized for a long time. Haploid production techniques including anther culture, isolated microspore culture and intergeneric hybridization between wheat × Hordeum bulbosum and wheat × maize have been used to produce homozygous lines which accelerate breeding programs. In this study, wheat × maize hybridization a...
متن کاملDifferent Salts Effects on the Germination of Hordeum vulgare and Hordeum bulbosum
The germination responses of Hordeum ulgare seeds to saline stress caused by different salt types was studied. For this, 25 seeds of mentioned species were placed on filter paper in Petri dishes containing distilled water (control), 60, 120, 180, 240, 300, 360 and 420 mM. saline solution of NaCl, CaCl2 an KCl. The results indicated that saline levels effects were significant (P < 0.05) for seed...
