In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

In order to study the survival mechanisms to drought stress for fruit body of Auricularia auricula, soluble carbohydrates and respiratory enzymes were investigated. Fruit bodies were exposed to sunlight and were naturally dehydrated. Samples were taken at different levels of water loss (0%, 10%, 30%, 50% and 70%) to measure the content of soluble sugars and polysaccharides. The activities of ph...

Background: The sterility mosaic disease in pigeon pea caused by virus is a serious threat to cultivation India. A little information available on the biochemical changes plant against SMD disease. Hence present study was taken know alterations different genotypes due Methods: Studies were conducted composition of chlorophyll pigment, total soluble protein (%), sugars, phenol, tannins, peroxida...

in order to evaluate effects of iron, zinc and manganese, and the methods of applying them on yield and yield components of sweet corn (zea mays saccharata), an experiment was performed as factorial based on randomized complete block design with four replications at the research farm of urmia university. experimental factors were micronutrient fertilizers with four levels (control, iron, zinc a...
