اثرات آللوپاتیک عصاره آبی پوست سبز میوه گردو بر برخی صفات فیزیولوژیک لوبیا قرمز

In order to investigate the allelopathic effect of walnut fruit green husk aqueous extract on physiological
characteristics of red bean, a factorial experiment was conducted in a randomized complete block design
with three replications at the research greenhouse of faculty of agriculture, Shahrekord university.
Treatments were concentrations of 12.5, 25, 50, 100 % of the walnut fruit green husk aqueous extract and
distilled water as control and also use three methods extract the soil at planting time, soil and foliar
applications were made during the 4-leaf beans. The results showed that the Walnut fruit green husk aqueous
extract has allelopathic effect. The data analysis showed that with increasing concentration, a decrease
chlorophyll a. As a control treatment and 12.5 % of the treated extract maximum and minimum
concentration was 100 % at planting time. The concentrations of foliar and soil application of 50 and 100 %
of the time 4 leaf extract method had the lowest chlorophyll b. The lowest carotenoid concentration was 100
% in the four-leaf stage. Leaf protein extract were affected of concentration and mode of administration and
were significantly lower than the control treatment and treatment of 100 % extract and how to use of the 4-
leaf the least amount of protein and control treatment had the highest amount of protein. Proline contents of
leaves affected and the concentration of the extract was used. With increasing concentration, as well as how
to use the 4-leaf extract and proline contents increased planting time. Appears to be an adaptation mechanism
might increase stress resistance.
