the reaction of nineteen different cultivars of cucurbita spp. including cucurbita pepo, cucurbita maxima and lagenaria siceraria to phytophthora capsici, phytophthora melonis and phytophthora drechsleri was studied under greenhouse conditions. plants were grown in steam sterilized soil. one-month-old plants were inoculated with vermiculate hempseed extract inocula of phytophthora and were floo...

The genus Cucurbita L. includes five cultivated species. C. pepo L., C. maxima Duchesne, and C. moschata Duchesne are the three most economically important. A high level of morphological and agronomical variability exists within these species. Large collections of Cucurbita landraces with a high potential value for breeding are maintained elsewhere. The COMAV’s Genebank at the Polytechnic Unive...

a r t i c l e i n f o The bees of the Peponapis genus (Eucerini, Apidae) have a Neotropical distribution with the center of species diversity located in Mexico and are specialized in Cucurbita plants, which have many species of economic importance, such as squashes and pumpkins. Peponapis fervens is the only species of the genus known from southern South America. The Cucurbita species occurring...

Eight major chemicals are identified after analyzing the essential oil of the seeds of three medicinal plants Punica granatum, Vitis vinifera and Cucurbita maxima, using Gas Chromatography/Mass Spectrometry (GC-MS). Only three of the identified chemicals (Farnesene, Docosane and Tetracosane) were found in all three samples, but in varying proportions. Trans-Squalene was found in Cucurbita maxim...

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...

Reports of snails’ resistance to niclosamide appeared recently and finding new molluscicides becomes necessary. We investigated the molluscicidal effects Cucurbita maxima seed extracts on Biomph...
