Embryo sac chromosome doubling in Populus alba × P. glandulosa induced by high temperature exposure to produce triploids
To determine the effects of the hours after pollination and the treatment durations on triploid production and reveal the effective stages of embryo sac chromosome doubling by high temperature exposure. At least three catkins were sampled, and 80 ovules were used for the determination of the embryo sac developmental process. Catkins (2-74 h after pollination) were treated to induce embryo sac c...
متن کاملInduction of 2n female gametes in Populus adenopoda Maxim by high temperature exposure during female gametophyte development
In order to produce triploid plants, 2n female gametes were induced by treating female buds and developing embryo sacs of Populus adenopoda Maxim with high temperature exposure. During megasporogenesis, tests were conducted on the relationship between female gametophyte development and morphological changes of female catkins. In the resulting progeny, 12 triploids were produced, and the highest...
متن کاملبررسی ریشه‌زائی دورگ های بین گونه‌ای صنوبر (Populus alba x P. euphratica) از طریق کشت مریستم
سابقه و هدف: گونه‌های مختلف صنوبر اهمیت زیادی در زراعت چوب پیدا کرده‌اند و دورگ‌های بین گونه‌های مختلف امید به افزایش تولید چوب را در کشور را افزایش دادهاند. بههمین دلیل تلاش‌های زیادی در دورگ‌گیری بین گونه‌های مختلف این جنس صورت گرفته است تا ضمن گسترش اساس ژنتیکی آنها، از همه قابلیت‌های موجود در آنها استفاده شود و دامنه اکولوژیک آنها را نیز افزایش دهد. دورگ‌های بین گونه‌ای ضمن ایجاد تنوع ژنت...

متن کاملBiological Dose Assessment by Chemical Induction of Premature Chromosome Condensation
Dose assessment of radiation victims is a key element in medical management of radiation accidents. At high radiation doses (> 6 Gy), dicentric assay lose its efficiency and premature chromosome condensation (PCC) assay was proposed to overcome the restrictions of dicentric assay. It was shown that PCC ring is more suitable and simpler than dicentric for biodosimetry in high radiation doses. In...
