in this research energy efficiency for greenhouse cucumber production in shahreza township located in esfahan province using data envelopment analysis (dea) technique was studied. in this study, data were obtained from 25 randomize active vegetable greenhouses from 60 greenhouses in shahreza township and villages environs. the results showed that the highest and lowest consumed energy were rela...

the effect of grafting on yield and some other quantitative and qualitative characteristics of two green¬house cucumber cultivars, namely roberto and danito grafted on five rootstocks of shintoza, kiroshintoza (cucurbita maxima × c. moschata), cucurbita maxima (c. maxima cv. goriki), fig leaf gourd (c. ficifolia cv. korodome), and bottle gourd (lagenaria siceraria) was investigated in this stud...

Leaf area index (LAI) values in plants affect photosynthesis and carbohydrate production directly since it is a measure of photosynthetically active the where transpiration occurs. an important parameter required to determine plant water consumption by using climatic data especially used calculation aerodynamic resistance. vary depending on varieties cultural practices can be determined indirec...

the chemical inputs threat the health of water, soil and organisms. thus, it is essential to encourage farmers to produce products with minimum use of chemical inputs. using the ordered logit model and a cross sectional data of 186 producers in 2012, this study attempted at investigating influential factors on willingness to accept (wta) of khorasan razavi province farmers to produce greenhouse...

It has been reported that ethylene production by cucumber plants is strongly related to the sex expression of their flowers. It has also been shown that both CS-ACS2 gene expression and ethylene evolution are much greater in gynoecious cucumber plants than monoecious ones. To investigate the action mechanism of ethylene in the induction of femaleness of cucumber flowers, we isolated three ethyl...

Plant disease has been a major constraining factor in the production of cucumber,the traditional diagnostic methods usually take a long time, and the control period is often missed. We take computer image processing as a method, preprocessing the images of more than 100 sheets of collected samples of cucumber leaves, using the region growing method to extract scab area of leaves to get three fe...

It is well established that the plant hormone ethylene plays a key role in cucumber sex determination. Since the unisexual control gene M was cloned and shown to encode an ethylene synthase, instead of an ethylene receptor, the 'one-hormone hypothesis', which was used to explain the cucumber sex phenotype, has been challenged. Here, the physiological function of CsACS2 (the gene encoded by the ...
