伊春地区不同种源五味子生长状况的比较

为了选出适合伊春栽培的最佳种源,研究了10个种源五味子建园后的生长性状、果实性状及产量。结果表明:栽培后第1年,五营和伊春种源在株高、地径上表现最好,栽培第2年和第3年,各种源间在株高、地径上无显著差异。五营种源单株和单位面积鲜果产量在各种源中最大。综合比较10个种源五味子在伊春地区的生长性状、果实性状及产量等的综合指标,初步选出五营种源为最佳种源,绥棱种源和伊春种源在果实产量上也是比较理想的种源。

Contrast of growth status ofSchisabdra chinensisfrom different provenances of Yichun region

In order to identify the optimal provenance ofSchisabdra chinensis suitable for cultivation in Yichun, growth characteristics, fruit characteristics and yield ofS. chinensis from 10 provenances were investigated after construction. The results showed that in the ifrst year after cultivation, heights and ground diameters of the plants from Wuying and Yichun provenances had the best performance. In the second and third years, plant heights and ground diameters of the plants had no signiifcant differences among provenances. Fresh fruit yields per plant and per unit area of S. chinensis from Wuying provenance were the biggest in all provenances. Through comprehensive comparison of the indexes of S. chinensis from 10 provenance of Yichun region, including growth characterisitic, fruit characteristic and yield, and so on, Wuying provenance was preliminary selected out as the best provenance, and Suiling and Yichun provenances were also the more ideal provenances from the aspect of fruit yield.
