The change of physiological activities in peanut (Arachis hypogaea L.) in response to different irrigation regimes and Ethanol foiliar application
In order to evaluate of physiological activities in peanut (Arachis hypogaea L.) in response to different irrigation regimes and Ethanol foliar application, an experiment carried out as split plat based on randomized complete block design with three replications in experimental field of Agicutural and Natural Resources Research and Education Center of Guilan Province, Astara (Kanroud research station), Iran during 2018 and 2019 cropping seasons. Four level of irrigation regimes at 25, 50 and 75 and 100 mm evaporation from class A pan and three levels of Ethanol 10, 20 and 30 % (v:v), comprised experimental factors, as main plot and sub plot, respectively. The interaction effect beween irrigation regime and Ethanol alcohol was significant for all measuered characteristics in peanut at 1% probability level. Drought stress caused to decrease grain yield per unit area, leaf chlorophy index and leaf relative water content in peanut. But, drought stress increased the value of proline, soluble sugar, soluble protein, anthocyanins and the activitiy of catalase, superoxide dismutase and peroxidase enzymes. The greatest grain yield (3275 kh/ha) was obtained in response to irrigation regime after 25 mm evaporation fron “A pan” along with foliar application of Ethanol at the rate of 20% (v/v). In general, result showed that the foliar application of Ehanol could be recommendable in direction to enhance grain yield and resistance of peant plans againest to drought stress under similar climatic condition.
