Alternative Effect Between Cucurbita pepo and Cucumis sativus On germination and some growth characteristic

Abstract

The present study was designed to determine the alternative effect between Cucurbita and Cucumis, the research involved two experiments in laboratory also in green house and the results showed that:-1-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5)%w:v in germination and seedling growth of Cucurbita. The results showed a variation that there is response in germination and growth when compared with the control, the highest percent of increasing was (33.3,23,7.3) % in the Cucurbita extract at (3%).On the other hand, the highest percent of reduction was ( 13.3,9,6) by effect of Cucumis extracts . 2-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5)%w:v in germination and seedling growth of Cucumis they caused reduction, the highest percent of reduction was (51.8,61.1,53.5)%, respectively at (3%) of Cucurbita extracts. 3-The effect of addition of Cucurbita & Cucumis residues in germination and growth of Cucurbita, the results revealed a different response, the highest percent which was ( 10,21.7,13.9,129.4,91)% were shown by Cucurbita residues that incubated for one week, while the highest percent of reduction was (20,40.2,28.4,24.5)% at the soil contain Cucumis residues without incubation.4-The effect of aqueous extract of Cucurbita and Cucumis at concentrations (0,3,5) % w:v in germination and seedling growth of Cucumis the highest increasing(10.6%) in germination and (11.6,4,8.8,1.3) % in growth for Cucumis residues that incubated, where is the highest reduction was (28.2,22.6,7.3, 27.2, 21.5) % respectively in the soil contain Cucurbita residues incubated.Also the results showed that Cucurbita and Cucumis residues (not incubated) and Cucumis residues incubated caused increasing content of carbohydrate in Cucurbita and Cucumis ,the highest value (31.82%) in Cucurbita affected by (Cucurbita residues not incubated),but the Cucurbita residues incubated caused reduction in content of carbohydrate in Cucurbita and Cucumis, the highest reduction (30.45%) in Cucurbita.
