The appropriate planting pattern of safflower in summer planting might be different from the planting pattern suitable for spring planting, and this has not been determined under Isfahan environmental conditions. A field experiment was conducted in the summer of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plo...

Under irrigation and in double-cropping system, a large amount of plant residue remains after harvest that along with the limited time for residue decomposition and complete seedbed preparation, necessitates reduced tillage and special residue management. In the present study, the effects of various seedbed preparation methods on vegetative growth, yield components and seed and oil yields of su...

The life of a plant unfolds as a series of developmental stages, with each stage defined by changes in meristem identity. In maize, there are several distinct stages: the transition from vegetative growth to flowering, the elaboration of the inflorescence, and the formation of flowers. Progress in understanding meristem identity and function has been made by analyzing maize mutants with defects...

Plant cell walls provide stability and protection to plant cells. During growth and development the composition of cell walls changes, but provides enough strength to withstand the turgor of the cells. Hence, cell walls are highly flexible and diverse in nature. These characteristics are important during root growth, as plant roots consist of radial patterns of cells that have diverse functions...

Density, distribution, and nutritional quality of plants are the causal basis of host plant selection in aphids. Nutritional qualities of a plant vary according to its growth stage and also in response to seasonal variation. How host plant growth stages shape aphid performance was studied in Aphis spiraecola Patch (Homoptera: Aphididae) on the perennial Siam weed, Chromolaena odorata (L.) King ...

گیاه درمنه خزری (artemisia annua l.) یکی از گیاهان دارویی و معطر از خانواده asteraceae می باشد. اهمیت عمده این گیاه ناشی از حصور یک لاکتون سزکوئی ترپن اندوپراکسید به نام آرتمیزینین است که علاوه بر خاصیت ضد مالاریایی قادر به از بین بردن انتخابی سلولهای سرطانی نیز می باشد. با توجه به مقدار اندک آرتمیزینین در این گیاه و غیر اقتصادی بودن ساخت شیمیایی آن کشت بافت آن به منظور تولید آرتمیزینین ضروری ب...
