Cucurbita pepo subsp. pepo var. Styriaca is a phylogenetically young member of the Cucurbita spp. since the mutation leading to dark green seeds with stunted outer hulls arose only in the 19th century. This mutation defined the so-called Styrian oil pumpkin and facilitated the production of Styrian pumpkin seed oil. It is a regional specialty oil in the south-eastern part of Europe. In this art...
chemical composition and physicochemical properties of pumpkin seeds and fatty acids of their oil were determined. it was found that the seeds contained 41.59% oil and 25.4% protein. moisture, crude fiber, total ash, and carbohydrate contents were 5.2%, 5.34%, 2.49%, and 25.19%, respectively. the specific gravity, dynamic viscosity, and refractive index of the extracted pumpkin seed oil were 0....
We have investigated the phylogenetic relationships among six wild and six domesticated taxa of Cucurbita using as a marker an intron region from the mitochondrial nad1 gene. Our study represents one of the first successful uses of a mtDNA gene in resolving inter- and intraspecific taxonomic relationships in Angiosperms and yields several important insights into the origins of domesticated Cucu...
Powdery mildew is a major fungal disease on squash and pumpkin (Cucurbita spp.) in the US and throughout the world. Genetic resistance to the disease is not known to occur naturally within Cucurbita pepo and only infrequently in Cucurbita moschata, but has been achieved in both species through the introgression of a major resistance gene from the wild species Cucurbita okeechobeensis subsp. mar...
به منظور بررسی تأثیر تراکم گیاهی و هرس ساقه اصلی بر عملکرد و اجزای عملکرد کدوی تخم کاغذی (cucurbita pepo con var. pepo var. styriaca) آزمایشی به صورت فاکتوریل در قالب طرح بلوک های کامل تصادفی در سه تکرار در دانشکده کشاورزی دانشگاه زنجان، در سال 1389 انجام شد. تأثیر تراکم گیاهی در سه سطح شامل8000، 12000 و16000 بوته در هکتار و هرس ساقه اصلی نیز در 3 سطح شامل (عدم هرس ساقه، هرس ساقه اصلی پس از تشک...
BACKGROUND The genus Cucurbita (pumpkin, squash, gourd) is native to the Americas and diffused to other continents subsequent to the European contact in 1492. For many years, the earliest images of this genus in Europe that were known to cucurbit specialists were the two illustrations of C. pepo pumpkins that were published in Fuchs' De Historia Stirpium, 1542. Images of fruits of two Cucurbita...
Impact assessments of virus resistance transgene introgression into wild, free-living populations are important for determining whether these transgenes present a risk to agriculture or the environment. Transgenic virus-resistant Cucurbita pepo ssp. ovifera var. ovifera L. (squash) cultivars have been commercialized, and may be cultivated in close proximity to cross-compatible wild, free-living...
قابلیت حیات بذرها به طور تدریجی طی انبارداری کاهش مییابد. صدمات وارده در سطح بیوشیمیایی باعث تغییر وضعیت فیزیولوژیکی بذر میشود و میزان خسارت به شرایط ذخیره بذر بستگی دارد. پراکسیداسیون لیپیدها توسط رادیکالهای آزاد اکسیژن نقش مهمی در کاهش قابلیت حیات بذر طی زوال دارد. در پژوهش حاضر، روابط بین فعالیت آنزیمهای پالاینده رادیکال آزاد (کاتالاز و پراکسیداز)، پراکسیداسیون لیپید و زوال بذر در کدوی ت...
