大果沙棘新梢生长、座果与产量研究

对同一试验园中的俄罗斯沙棘、蒙古沙棘大果品种和中国沙棘(对照)的新梢生长动态、新梢生长量、生长势、座果、产量和果实主要性状进行了系统地比较研究。结果表明：中国沙棘新梢生长量、生长势和座果率强于俄罗斯沙棘和蒙古沙棘生长。从产量上看，俄罗斯沙棘“金阳”单株产量最高，中国沙棘最低。从果实主要性状看，俄罗斯沙棘“巨人”和“金阳”最好，其次为蒙古沙棘“秋阳”，中国沙棘较差。

Studies on Shoot Growth, Fruit Setting and Yield of Sea Buckthorn

Growth dynamics, shoot growth vigor, fruit setting, and yield of sea buckthom cultivars from Russia, Mongolia and China(ck), which are growing in the same orchard, were studied. The results showed that shoot growth length, growth vigor and fruit setting rate of H. rhamnoides are higher than those of cultivars from Russia and Mongolia. The yield of "Golden sun" is the highest and that of Chinese sea buckthorn(H. rhamnoides L. subsp, sinensis Rousi)is the lowest. The main fruit characters of "Giant()" and "Golden sun" are better than those of "Autumn sun" and Chinese sea buckthorn( H. rhamnoides L. subsp, sinensis Rousi)
