Effect of Foliar Spraying by Methanol on Growth of Common Bean and Snap Bean in Rasht, North of Iran

摘要

An experiment was conducted to evaluate the effects methanol spraying on growth of common bean and snap bean in Rasht, North of Iran. This experiment was done as a randomized complete block design for split-plot in three replications. The main-plot factor was variety in tow levels (common bean and snap bean) and the sub-plot factor, i.e., methanol use was considered at five levels (0, 10, 20, 30 and 40% methanol concentration). Results showed that maximum plant height, pod length, number of seeds per pod, number of pods formed per plant, number of ripe pods per plant and number of seeds per plant were in snap bean variety (p<0.01). Also, effect spraying methanol on number of seeds per pod, number of ripe pods per plant and number of seeds per plant were significant (p<0.01) that maximum average of number of seeds per pod (M = 8.5), number of ripe pods per plant (M = 7.8) and number of seeds per plant (M = 101.83) were in treatment of 40% methanol concentration and maximum plant height (M = 42.28 cm) was in 10% methanol concentration.
