A Rapid and Nondestructive Method for Estimating Leaf Area of Onions

A Simple and Rapid Leaf Genomic DNA Extraction Method for Polymerase Chain Reaction Analysis

In plants, secondary metabolites and polysaccharides interfere with genomic isolation procedures and downstream reactions such as restriction enzyme analysis and gene amplification. The removal of such contaminants needs complicated and time-consuming protocols. In this study, a simple, rapid and efficient method for leaf DNA extraction was optimized. This method use small amount of plant mater...

Leaf area estimation by a simple and non-destructive method

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Rapid estimation of sunflower leaf area from linear measurements

A REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA

Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
