摘要
本文对内蒙古地区南瓜属3个主要栽培种的6个品种的种子粗脂肪含量，脂肪在开花授粉后的增长规律，脂肪酸的组成进行了系统研究。结果表明；印度南瓜的种子粗脂肪含量高于其它2个种，达到54．93％。3个栽培种的脂肪增长规律基本一致，授粉后28～35d是增长最快期，14～28d和35～49d是增长缓慢期。美洲南瓜与印度南瓜种子不饱和脂肪酸含量高于中国南瓜，分别达到58．89％和52．42％，而且它们的商品性状好，可以认为印度南瓜与美洲南瓜是我区优质的籽用南瓜品种资源，这为内蒙古籽用南瓜的种质资源开发利用提供了理论依据。
The study was carried out to analyze the increment of raw fat and fattyacid and component of the fatty acid in seeds after pollination in six commonly cultivatedvarieties of three species of seed-pumprin in Inner Mongolia. The Results showed thataverage content of raw fat in seeds of C. maxima was 54. 93%,higher than that of theother species. The Incrementu pattern of raw fat in the three species was the same. It increased rapidly from 28 to 35 day,after pollination. Seeds of C. pepo and C. maximaContained 58. 95% and 52. 42% unsaturated fatty aeid,respectively higher than that ofC. moschata. Moreover, their seeds were superior to C. moschata seeds in commerlialcharacter. C. maxina and C. pepo were regarded as excellent cuitivated varieties of seed-pumpkin
