Principal component analysis was used to ordinate 216 weather stations in area of oil-tea camellia, and to group them into geographical climatic regions. Regional variation of temperature and summer precipitation show their significance in the first and second components which have been used to stratify the climatic regions. A scheme of 5 geographical climatic regions has been proposed, namely, northern region (N), central region (C), central southern region (CS), southern region (S) and western region (W).

本文以主成分分析法,将我国油茶产区216个测候站,按所选用的12项气候因子,作成分布序列,并利用测站在样品空间之分群,划定油茶栽培地理气候区。年均温、一月均温和夏季降水量之区域性变异,构成第一及第二主成分,为油茶地理气候区划分的基础。如此计分为北、中、中南、南、西五个大的栽培地理气候区。中区又以花期降水(构成第三主成分)这一因素,将湘西、黔东、鄂西南单独标出。北区属过渡的亚热带气候,中区属典型亚热带气候,中南区为中亚热带向南亚热带过渡型气候,南区为高温高湿型南亚热带气候,西区为夏雨型气候。

Heritability, genetic correlation, and principal components of 10 qualitative characters of rice were analysed. Results showed that the characters with high heritability are amylose content, seed shape, seed longness,chalkiness rate, brown rice rate and milled rice rate.Amylose content has a close positive correlation with chalkiness and chalkiness rate, and a close negative correlation with alkali spreading value and milled qualitative characters. The unbroken rice rate has a close negative correlation with...

Heritability, genetic correlation, and principal components of 10 qualitative characters of rice were analysed. Results showed that the characters with high heritability are amylose content, seed shape, seed longness,chalkiness rate, brown rice rate and milled rice rate.Amylose content has a close positive correlation with chalkiness and chalkiness rate, and a close negative correlation with alkali spreading value and milled qualitative characters. The unbroken rice rate has a close negative correlation with protein content, chalkiness, seed shape and seed longness.The analytical results of principal components showedj first, the principal component was the unbroken rice and amylose content; secondly, chalkiness) and thirdly, alkali spreading value. Therefore, the milled rice rate, amylose content, magnitude of chalkiness , chalkiness rate and alkali spreading value are considered as the principal characters in identifying rice quality.

对水稻10个主要品质性状进行了遗传力分析、遗传相关分析和主成分分析。结果表明:广义遗传力较高的性状有直链淀粉含量、粒形、粒长、垩白米率、糙米率和精米率。直链淀粉含量与垩白大小及垩白米率有较密切的正相关,与碱解值和碾米品质性状有较密切的负相关;整精米率与蛋白质含量、垩白大小、粒形和粒长有密切的负相关。主成分分析结果表明:第一主成分为整精米、直链淀粉因子,第二主成分为垩白因子,第三主成分为碱解值因子。认为整精米率、直链淀粉含量、垩白大小、垩白米率和碱解值为鉴定稻米品质的主要性状。
