تحقیق حاضر برای به دست آوردن اطلاعاتی از تأثیر فاصله‌ی بین ردیفی گیاه Brassica napus L. روی جمعیت شته‌ها آغاز شد. سه فاصله‌ی خطی (20، 30 و 40 سانتی‌متری)، با فاصله‌ی ثابت نه سانتی‌متر بین هر گیاه‌، روی آلودگی شته و تأثیرش روی محصول دانه ارزیابی شد. اطلاعات جمع‌آوری و تصحیح شده روی پارامترهای ثابت نشان داد که افزایش فاصله‌ی خط‌ها با جمعیت شته رابطه‌ی معکوس دارد. با کاهش فاصله‌ی داخلی ردیف‌ها، اف...

Cultivation of a second crop in paddy fields of Guilan province is a strategy for optimum use of land, supporting family economy and increasing oil-seed production. However, this is impeded under high rainfall and waterlogging conditions. To enhance second-crop cultivation in paddy fields, surface drainage is inevitable. The surface drainage practices should be performed with minimum costs, l...

Conocarpus erectus L. is a fast growing tree, drought resistant and it is widely planted throughout Saudi Arabia around parking lots and along the streets. It constitutes a renewable resource that could be used as a source of raw materials required for several uses. However, no data were available about its wood quality. This study was established to investigate the effect of plant spacing on s...

C sequencing of higher eukaryotic genomes yielded the surprise that despite hundreds of millions of years of evolutionary separation and strikingly different sizes and body plans, diverse organisms contain nearly the same number of genes! Gene prediction is '30,000 for human (1), slightly lower for other animals (2), including 13,600 for the fruit fly Drosophila melanogaster, 18,400 for the nem...
