High-density genetic map is a valuable tool for fine mapping locus controlling a specific trait especially for perennial woody plants. In this study, we firstly constructed a high-density genetic map of mei (Prunus mume) using SLAF markers, developed by specific locus amplified fragment sequencing (SLAF-seq). The linkage map contains 8,007 markers, with a mean marker distance of 0.195 cM, makin...
به منظور بررسی تکثیر قلمه ای درختچه زینتی فردوسی، آزمایشی در دو بخش عملیاتی گلخانه ای و آزمایشگاهی (ریزازدیادی) در سال 1389 در پردیس دانشگاه علوم کشاورزی و منابع طبیعی گرگان انجام گردید. در بخش گلخانه ای، اثرات بسترهای کشت، غلظت های مختلف اسید ایندول بوتیریک و زمان گرفتن قلمه در ریشه زایی قلمه ها در شرایط مه افشان در قالب طرح اسپلیت پلات بر پایه کاملاً تصادفی مورد ارزیابی قرار گرفت. محدوده علظت ...
A survey of exotic beetles that attack trees or shrubs in New Zealand found 51 species of mainly Australian (58%) and European (25%) origin. In addition, three biological control agents have been released against woody adventive plant pests. The host range of most species is restricted to exotic crop and ornamental plants in New Zealand. Nine polyphagous borers sometimes attack dead wood of ind...
