نیتروژن به عنوان ضروری ترین عنصر معدنی برای رشد گیاهان می باشد. بیشتر گیاهان عالی نیتروژن مورد نیاز خود را به فرمهای نیترات و آمونیوم به دست می آورند. آزمایشات اولیه با اندازه گیری کینتیک جذب نیترات نشان می دهد که در گیاهان عالی حداقل دو سیستم انتقال نیترات وجود دارد .سیستم lats (low affinity transport system) با تمایل کم که در غلظت بالاتر از ?/0 میلی مولار نیترات فعال می شود و سیستم تمایل بالا...
An investigation of the population parameters of Indian mackerel, Rastrelliger kanagurta (Cuvier, 1816) in the Marudu Bay, Sabah, Malaysia was carried out from January to September 2013. The relationship between total length and body weight was estimated as W=0.006TL3.215 or Log W=3.215LogTL – 2.22 (R2=0.946). Monthly length frequency data of R. kanagurta were analyzed by FiSAT software to eva...

This study was carried out to determine population structure, growth and reproduction properties of barbel. A total of 198 individuals were sampled. Ages of samples were found between I and VI years, fork lengths between 4.3 and 16.6 cm and total weights between 1.2 and 65.8 g. Length-weight relationship was calculated as W=0.0146×L2.934. Munro’s phi prime index was estimated as 1.95, L∞ ...
