Study of Foliar Application of Methanol on Drought Stress Resistance in Barley (Hordeum Vulgare L.)
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 2
Abstract
In order to study of foliar application of methanol on drought stress resistance in barley, an experiment was conducted in 2012-2013 in the farm of karafshan village in mobarakeh city located in southern Isfahan province (latitude 32o /34' N and Longitude 51o /44' E). A split factorial layout within randomized complete block design with 4 replications was used. Main plot were different level of drought stress (full irrigation, stop of irrigation at stem elongation stage up to physiological maturity, stop of irrigation at pollination stage up to physiological maturity), and sub plots were various concentrations of foliar methanol including (0, 15% and 30%), and foliar times (tillering, stem elongation and flowering). Condition represented the effect of irrigation disruption was significant on number of seeds spike-1, 1000 seed weight, seed yield and biological yield. Control treatment resulted the maximum of all mentioned factors except number of seeds spike-1. Effect of methanol concentrations was significant on number of seeds spike-1 and biological yield. Foliar time effect only was significant on 1000 seed weight and the maximum of it related to foliar on tillering stage. HI was affected by interaction effects of all treatments. On the basis of the results obtained, use of methanol with a concentration of 30% at tillering stage due to an increase in seed yield and harvest index, might be suitable for barley productive under the condition similar to the present study.
