Title
Assess Effect Of Seed Priming On Growth Of Chickpea (Cicer arietinum L.) Under Rainfed and Irrigated Conditions
Authors
Abstract
In order to enhance plant growth of chickpea and complete the escape mechanism from season terminal drought, a study with the aim of evaluating effect of gibberellin and abscisic acid on root growth and plant growth rate and some physiological characteristics of chickpea seedling under rainfed and irrigated condition was conducted in agricultural collage research farm of Lorestan University. Hormones were used as priming and moisture treatments as irrigated and rainfed condition. Seeds were primed separately with 0, 50, 100 and 150 ppm of gibberllin and abscisic acid. Chickpea cultivar was Filip 93-93 and experimental design was split plot in base of completely randomized block design. Results showed that number of primary lateral branches are the same in both irrigated and rainfed conditions. Leaf area index (LAI) was greater in irrigated condition than rainfed. Abscisic acid 150 ppm increased root length in rainfed condition. Hydropriming increased root length, dry and wet weights of root, leaf area, seedling growth rate and the number of lateral roots.
