This experiment was conducted at Azad University experiment station to evaluate the effects of planting date and time of nitrogen application on yield and sugar content of sweet sorghum in 2003. Four planting dates (May 4, March 19, June 3 and June 18) and three stages of nitrogen application (3-5/8 leaf stage, boot stage and soft dough stage) were assigned to the main and subplots, respectivel...

Ginseng has been used as a general tonic agent to invigorate the human body as an adaptogenic agent. In a previous report, we have shown that ginseng contains a novel glycolipoprotein called gintonin. The main function of gintonin is to transiently enhance intracellular free Ca(2+) [Ca(2+)]i levels in animal cells. The previous method for gintonin isolation included multiple steps using organic...

in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

Correlation coefficient analysis conducted on 22 triticale x bread wheat derivatives along with six checks to select true- breeding derivative(s) for future hybridization programme with tolerance to drought and cold stress conditions as well as better quality traits revealed significant correlation of grain yield with spikelets per spike, biological yield, harvest index, leaf area index. Intere...

Sex expression in cucumber is influenced by hormonal and environmental factors such as day length and temperature. Increasing female flowers that will develop to fruit is a trick for increasing yield, hence it’s importance. Likewise, it would help breeders through hybridizing process. Ethylene as a plant hormone is known to increase female flowers of most members of Cucurbitaceae family but as ...
