water and soil salinity are two of the most important limiting factors in crop production. phosphatase enzymes are widely found in plants. phosphatase enzymes are responsible for de-phosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted using two bread wheat cultivars, namely, iniya66 and ghods along with application of different nacl p...

Rice is the staple food for half of world's population. Phosphorus an essential element rice plant growth, development and production; however, availability soluble phosphate uptake often limited due to binding with cation in different pH environments. Therefore, varieties, which can grow well under a environment, urgent need agricultural biotechnology. This study reported two contrasting varie...

in order to determine the effect of different irrigation intervals on some morphophysiological traits of basil (ocimum basilicum l.), an experiment was conducted as factorial based on randomized complete block design with three replications under greenhouse conditions during 2010. treatments included five irrigation intervals with 4, 8, 12, 16 and 20 days intervals and two ecotypes of basil (gr...

Our purpose is to show by means of a quantitative method for determination of hydrindantin derivatives that previous concepts of the mechanism of the reaction of ninhydrin with amino acids are inadequate or erroneous, and to show facts supporting a new concept. The main facts are as follows: (a) Hydrindantin forms when amino acids react with ninhydrin (Ruhemann (1) ; Abderhalden (2)) ; (b) it r...
