黑核桃优良品系表型测定技术研究

Phenotype Test Research on Good Family of Black Walnut

新疆引进黑核桃(Juglans nigra)七个优良品系嫁接苗在南、北疆分别定植,经过5年的系统观测表明:不同品系间生长物候无明显差异,适应性和生长量间表现出较大差异。初步选择出适宜新疆不同生态区生长快、抗性强、推广应用价值较大的3个优良品系。

The grafting seedling of seven quality varieties of black walnut（Juglam nigra ） was introduced into Xinjiang, respectively to be planted in South and North Xinjiang.The result after 5 years systematic observation indicated that there was no obvious difference in periodic biological phenomena between different quality varieties. But there was great difference in adaptability and amount of growth. The 3 quality varieties, which were suitable for different ecological area, grew fast, had strong resistance, had greater value of populization and application, were preliminarily selected.
