in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...

landraces are a valuable source of genetic diversity for varietal improvement. despite, iran is the fifth squash and pumpkin producer, but no available information exists about the diversity of summer squash landraces. in order to evaluation of floral and fruit production characteristics among four iranian summer squash and a check cultivar of f1 hybrid ‘asma’, an experiment was conducted in a ...

The properties of starches isolated from two squash cultivars (Cucurbita maxima) were studied and compared with those of two pumpkin cultivars (Cucurbita moschata) and one normal potato cultivar. The amylose content of pumpkin and squash starches ranged from 16.18% to 21.29%. The pumpkin and squash starches appeared as a mixture of spherical, polyhedral and dome shaped granules. The pumpkin and...

Recent declines in managed honey bee, Apis mellifera L., colonies have increased interest in the current and potential contribution of wild bee populations to the pollination of agricultural crops. Because wild bees often live in agricultural fields, their population density and contribution to crop pollination may be influenced by farming practices, especially those used to reduce the populati...

The black-rot fungus, Myeosphaerella melonis (Pass.) Chiu and J. C. Walker, was first reported in France in 1891 on leaves of a Chinese variety of cucumber {CueUQyiis sativus L.) (¡^i) .^ It was recorded the next year from Delaware on vines of watermelon {Gitrullus vulgaris Sehr ad.), squash {Cucúrbita spp.), pumpkin {Cucúrbita pepo L.), muskmelon {Cucumis meló L.), and cucumber {3). Grossenbac...

The word “pumpkin” is derived from the Latin word pepo, which is a botanical term for fruit with a hard rind and fleshy interior. The commonly used scientific name for pumpkins is Cucurbita pepo. But some other cucurbits, such as Cucurbita moschata (e.g., ‘Dickenson’ and ‘Libby Select’, known as processing pumpkin) (Figure 1, B) and Cucurbita maxima, which are winter squash, are also known as p...

Field survey of the cucurbit crops revealed a high incidence of Cucumber green mottle mosaic virus (CGMMV) in Khyber Pakhtunkhwa Province (KPK), Pakistan. Among the seven districts surveyed, average percent incidence of CGMMV was recorded up to 58.1% in district Nowshera, followed by 51.1% in district Charsada, 40.5% in district Swabi and 37.3% in district Mardan. In Swat and Dir districts aver...

Several species from the Cucurbitaceae family including muskmelon, watermelon, cucumber, pumpkin, and squash were used to evaluate their tolerance in a laboratory test to two herbicides (Stomp and Acetochlor) widely used in crop cultivation. The effects of concentration and site of herbicide action on the length of primary roots and hypocotyls as well as seedling fresh weight were studied. The ...
