Morphological, Thermal and Physicochemical Properties of Starches from Squash (Cucurbita maxima) and Pumpkin (Cucurbita moschata)
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...
متن کاملAntioxidant Enzymatic Activities and Gene Expression Associated with Heat Tolerance in the Stems and Roots of Two Cucurbit Species (“Cucurbita maxima” and “Cucurbita moschata”) and Their Interspecific Inbred Line “Maxchata”
The elucidation of heat tolerance mechanisms is required to combat the challenges of global warming. This study aimed to determine the antioxidant enzyme responses to heat stress, at the enzymatic activity and gene expression levels, and to investigate the antioxidative alterations associated with heat tolerance in the stems and roots of squashes using three genotypes differing in heat toleranc...
متن کاملInheritance Studies of the Interspecific Cross of the Cucurbita Lundelliana Complex X Cucurbita Moschata
Two populations of Cucurbita were studied for the inheritance of corolla pigments. Flowers from them were collected--classified as orange, yellow, or cream--and analyzed for total carotenoid pigments. In most cases, chemical analysis for total pigments agreed with observed color designations. The ? 2 and backcross results fitted the expected 1:2:1 and 1:1 segregations, respectively, found in th...
متن کاملDevelopment of Advanced Interspecific-bridge Lines among Cucurbita pepo, C. maxima, and C. moschata
Interspecific hybridization among the three most economically important cultivated species of Cucurbita spp., Cucurbita pepo, C. moschata, and C. maxima can be made but not readily. By means of various pollination measures, different mating systems, and varying selection methods, nine advanced interspecific-bridge lines were developed, in which the crossing barrier among the species and the mal...
متن کاملthe possibility of interspecific hybridization between summer squash (cucurbita pepo) and pumpkin (c. moschata)
interspecific hybridization occurs among cucurbia species it is commonly used for grafting, yield increasing and production of pest resistant rootstocks. in the present research probability of interspecies hybrid generation among seven lines of cucurbita pepo (p1, p4, p5, p6, p10, p22, p25) and six lines of cucurbita moschata (mo3, mo5, mo6, mo9, mo11, mo12) were investigated. after crossing of...
