Agrawal, A. A., Janssen, A., Bruin, J., Posthumus, M.A., Sabelis, W. M. 2002. An ecological cost of plant defense: attractiveness of bitter cucumber plants to natural enemies of herbivores. Ecology Letters 5: 377-385. The authors examine this tritrophic system from the bottom-up perspective by comparing the direct plant defense of producing the bitter compound, cucurbitacin, which repels the he...

with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...

Strain XN-1 isolated from the cucumber phyllosphere was tested for potential application as an antagonistic actinomycete against Corynespora cassiicola (Berk.& Curt.)Wei. The fungistatic activity of this strain was determined by inoculation of C. cassiicola on PDA plates, spore germination inhibition in culture filtrate and control tests on cucumber leaves. The spore germination and hyphal grow...

in order to study the role of phytophthora species associated with greenhouse cucumber root and crown rot, diseased sampled were collected in southern kohgiluyeh and boyerahmad province. pieces of infected root and crown of cucumber were washed with tap water blotted dry and plated on cma supplemented with delvocid (10 ppm pimarcin), ampicillin (250 ppm), rifampicin (10 ppm) and pcnb (150 ppm)....

The cucumber moth, Diaphania indica (Saunders) (Lepidoptera: Pyralidae), is a tropical and sub-tropical cucurbits pest and a key greenhouse pest in the Jiroft region of Iran. In this study, the effect of different temperatures on the development of this pest was investigated on cucumber, Cucumis sativus L. (Cucurbitales: Cucurbitaceae), leaves in a growth chamber at various constant temperature...

damping-off disease of cucumber caused by soil-born fungi pythium aphanidermatum is one of the most destructive diseases of cucumber. in this research, the effect of three bio-fertilizers including; nitroxin, mycorrhiza and vermicompost in single and combined form on induced resistance and yield components in greenhouse cucumber (es-2862) infected with damping-off disease was investigated. thes...
