软儿梨优株选择研究

Research on of Soft Pear Superior Choice

研究了青海地产软儿梨在多种生长性状指标上的特征。通过对可溶性固形物含量的测定将参加试验的单株进行了初步划分，深入研究了多种性状指标，并进行主成分二维排序，又通过对多个性状指标的分析对参加试验单株进行综合评价并排序，最终确定优株。

Qinghai real estate soft pear in many kinds of growth character target characteristic has stud- ied. soluble solid shape content＇ s determination has carried on the preliminary division, the deep research many kinds of character targets, and carried on principal components two - dimensional sorting. Also through to participates to many character target＇ s analysis experiments single to carry on the quality synthetic evalua- tion and to sort, determines superior finally.
