اثر محلولپاشی متانول و آسکوربیک اسید بر عملکرد و اجزای عملکرد لوبیا در رشت

In order to evaluated the effect of methanol and ascorbic acid foliar on growth and yield of bean, a
factorial experiment with the base design of random is complete block design 3 replication was
conducted in Rasht 2013. Methanol in 4 levels (0, 10, 20 and 30 V/V) and ascorbic acid in 4 levels
(0, 1, 2 and 3 g/lit) were factors of the study. The following charaetristics were studied: no. seeds
per plant, no. of pods per plant, plant height, 100 seed weight, fresh pod yield. The analysis of
variance indicated that foliar of methanol had significant effects on fresh pod yield,no. seed, pod
no, 100 seed weight and plant height. Ascorbic acid had no significant effects on yield and yield
components. The comparison of means indicated that by increasing the amounts of methanol to 30(
V/V) of more evaluated characteristic were affected. It has been showed that the volume of 30(V/V)
methanol was suitable for beans plant, as well as The interaction of methanol and ascorbic acid
amounts on the plant height and seed no. were significant. The highest seed no. was obtained while
it has been sprayed by 30 (V/V) of methanol within 2 (g/lit) of Ascorbic acid.
