To investigate the ontogeny of Perccottus glenii, embryonic, larval and juvenile development of P. glenii were examined under captive condition. The fertilized eggs with numerous oil droplets were orange-pink in color, prolate spherical in shape and had average length of 3.32±0.14 mm and width of 1.24±0.04 mm. From fertilization to hatching, the ontogenesis of the fish spent more than 200...
the study was conducted to evaluate the effect of seed priming on root growth of two barley cultivars (hordeum vulgare l.) under salinity stress was performed in phytogel. the treatments included two cultivars of barely (yusuf and maquie), levels of seed priming (control, hydro-priming and priming with 4.35 g l-1 of urea) and four levels of nacl salinity stress (0, 0.2, 0.3 m). the experiment w...

در این پژوهش که بمنظور ارزیابی تاثیر الگوی مسلح سازی توسط ژئوگرید بر کمانش جانبی ستون سنگی و تغییرات کمی و کیفی کمانش ستون انجام شده است، با در نظر گرفتن سه حالت مسلح سازی و تحلیل توسط نرم افزار اجزاء محدود plaxis انجام شد. حالات مسلح سازی شامل تمام مسلح(full length)، مسلح شده موضعی(local) و مسلح شده ترکیبی (combined)، برای ارزیابی تغییرات حداکثرکمانش جانبی(lbm)، کاهش حداکثر کمانش (lbrm)، عمق...
The structure and histogenesis of the stigma of Datura stramonium was investigated by light and scanning electron microscopy to determine the developmental origin of the transmitting tissue and “wet stigma”. Four developmental stages were defined on the basis of bud length. Stage one, the histogenesis stage, was comprised of buds 2-15 mm in length. Stage two, signified by the growth and develop...
