chana_prorAbstract

In order to study the effect of priming and salinity on seed germination, physiological characteristics and grain yield of chickpea, an experiment was carried out under hydroponic condition. Results showed that germination percentage and rate significantly reduced under salt stress. KNO3 was proper trait than that of hydro-priming to improving germination rate. Leaf area index (LAI) and membrane stability index (MSI) reduced under salt stress specially sever salt level (S3). Seed priming had no effect on LAI and MSI. In contract, primed plants significantly increased leaf water content (LWC). KNO3 under sever salinity condition improved LWC of chickpea. Loss of grain yield under sever salt stress in comparison to control was 76%. Priming seed by water and KNO3 enhanced grain yield approximately 13% and 27%, respectively in comparison to control. As a result of this research chickpea was sensitive plant to salinity and priming especially by KNO3 can be improved physiological characteristic and grain yield of this plant.

Key words: Polyester, weight reduction, cotton, sodium hydroxide, QAC.

CottonAbstract

An environmentally friendly pad-steam process for treatment of polyester/cotton fabric with sodium hydroxide was developed. To enhance the process efficiency, a quaternary ammonium compound (QAC) besides a reducing agent was used. Using QAC, the rate and amount of weight reduction were increased. Continue reading
