  • 印度南瓜和中國南瓜種間雜交種的特性與應用 相關:印度南瓜 中國南瓜 種間雜交種
  • 印度南瓜和中國南瓜的種間雜交種,有著不同于親本的特征特性,在種子生產和商品瓜栽培管理上有特殊要求。中國南瓜(Cucurbita moschata Duch.,俗稱南瓜)和印度南瓜(Cucurbita maxima Duch.,俗稱筍瓜)是南瓜屬作物中的主要栽培種。印度南瓜和中國南瓜的種間雜交,創新了南瓜屬種質資源,也培育出了印度南瓜和中國南瓜的種間雜交種。
  • 《中國南瓜史》序 相關:中國南瓜 萬國鼎 坎坎坷坷
  • 昕升博士將其書稿《中國南瓜史》電子版發來,囑為其作序。我在倍感榮幸之余,又深感惶恐。鄉賢歐陽修有言:“不怕先生罵,卻怕后生笑。”昕升博士,以而立之年,便完成了一項農史研究的拓荒之作,真是后生可畏。中國的農史研究事業,自先賢草創,已近百年,其間風風雨雨,坎坎坷坷,至今薪火相傳,后繼有人。其中南京農業大學的中國農業遺產研究室一直走在全國的前列。
  • Fatty Acid Accumulation in Seeds of Three Seed Pumpkin Cultivars 相關:SEED PUMPKIN CUCURBITA
  • In the literature there are many reports on the composition and properties of pumpkin seed oil; however, few is known about the effect of different stages of seed development on various fatty acid profiles in developing seeds. The objective of this study was to provide the changes of various fatty acid accumulations in seed oil obtained from the seeds of three pumpkin varieties belonging to the species Cucurbita maxima and Cucurbita pepo. Unsaturated acids (oleic and linoleic) were dominant in various fatty acids, which constituted 38.9%-49.1% and 29.4%-42.7% of the total fatty acids at seed maturity for three pumpkin varieties, respectively, while other fatty acid concentrations except for palmitic acid all did not reach 10%. Different varieties exhibited greater effect on various fatty acid contents and the total fatty acid contents in the seeds of pumpkin rather than the species. On the whole, palmitic acid profiles of the seed oil in three varieties all followed the fluctuant decrease during all the stages of seed development, but palmitoleic acid and the total fatty acid profiles of the seed oil in three varieties were just the opposite. Stearic, oleic and linoleic acid profiles of the seed oil in three varieties all experienced the third pattern that fluctuated during all the stages of seed development, but no significant differences in these three fatty acid concentrations were found from the beginning to the end. Linolenic acid concentrations of three varieties were on the decline and ultimately close to zero. Myristic and arachidic acid profiles of the seed oil followed different trends in three varieties. Among them, myristic and arachidic acid profiles of the seed oil of Yinhui-1 fluctuated downward all the time until seed maturity, but those of 0238-1 and Jinhui-2 completely changed oppositely.
