Abstract: Growth characters and their relationship with fruit yield of 13 Large Berry Cultivars of Sea buckthorn(Hippophae rham noides) were studied at two sites, Shuiling of Heilongjiang(47°13′N, 127°7′E) and Dengkou of InnerMongolia (40°20′N, 106°59′E). The results showed: ( 1) The length of Large Berry Cultivars has not obviousdifference between two trial p lots, the width of Large Berry Cultivars in Dengkou county was smaller than that inSuiling county, the difference of leafwidth and length varied with different cultivars; the leaf length of Chinese SeaBuckthorn was obviously smaller than that ofLarge Berry Cultivars, and the width was similar; the rate of leaf lengthto width in Dengkou was obviously higher than that in Suiling, the rate of leaf length and width can be viewed as anindex to compare the resistance and adap tation of different cultivars. (2) The number of branch thornswas differentamong different cultivars, and the amount was not equal for the same cultivar in different trial p lots, in Dengkou county, the amount of branch thorns had obvious increasing trend, which maybe an adap tation to drought, and thisadap tation was the reason why that Chinese Sea Buckthorn grew the most branch thorns. (3) The height, ground diameter and crown diameter of most Large Berry Cultivars in Dengkou were all lower than that in Suiling, thesegrowth indexes of Chinese Sea Buckthorn were obviously higher than that ofLarge Berry Cultivars. (4)Different cultivars could get to 10 000 kg?hm-2. (5) The correlation between grow and yield of differentLarge Berry Cultivarswas different, and yield could be effectively p redicted through growth indexes, but a perfect p rediction system stillneedsmore p ractical data to build.
