Net photosynthesis, growth, and ultraviolet (UV) radiation absorbance were determined for the first leaf of Cucurbita pepo L. exposed to two levels of UV-B irradiation and a UV-B radiation-free control treatment. Absorbance by extracted flavonoid pigments and other UV-B radiation-absorbing compounds from the first leaves increased with time and level of UV-B radiation impinging on leaf surfaces...
The ribosomal DNA (rDNA) of Cucurbita pepo L. has been found to consist of tandemly arrayed repeat units, most of which are 10 kilobases in length. Thirty-six repeat units, cloned into the HindIII site of pACYC 177, fall into seven classes which differ from each other in length and/or nucleotide sequence. Most of the heterogeneity occurs in noncoding portions of the repeat unit although there i...
Salinity is a major environmental stress that causes severe damage to crop and horticultural products and also reduce plant biodiversity. Today with using grafting method overcome problem of soil salinity and ultimately, higher-quality products are yield of. In this study, water melon (cv. Sugar baby) was grafted on to the hybrid rootstocks of shintozwa (Cucurbita maxima×Cucurbita moschata), pe...
Seeded pumpkins are important economic crops; the seeds contain various unsaturated fatty acids, such as oleic acid and linoleic acid, which are crucial for human and animal nutrition. The fatty acid desaturase-2 (FAD2) gene encodes delta-12 desaturase, which converts oleic acid to linoleic acid. However, little is known about sequence variations in FAD2 in seeded pumpkins. Twenty-seven FAD2 cl...
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...
