The Adaptive Research Of Introduction Cultivation In Preliminary Stage Of Six Large Berry Seabuckthorn In Shanxi

In order to comprehend the ecological suitability of large berry cultivars of seabuckthorn in Shanxi province, Jiuyuenhuang, Zhuangyuanhuang, Brazil hongyun, hybridize1, hybridize2, hybridize3and hybridize4which are imported from Fuxin, Liaoning are research object, and observe the growing performance,the berry number by taking Chinese sea-buckthorn as comparison. This research the difference of growth, adaptability and nutrients between large berry and Chinese sea-buckthorn.At the same time, Seabuckthorn twig cutting with different treatments make a preliminary study.The results are as followsPhenological phase:Forming stage and trend of leafing stage of imported large sea-buckthorn are all later than Chinese sea-buckthorn; while the leaf falling stages is earlier and growing cycle is shorter than Chinese sea-buckthorn, hybridize3has the longest growing cycle which is229days, but Brazil hongyun has the shortest growing cycle which is211days among different large sea-buckthorn cultivarsGrowing performance:6large sea-buckthorn cultivars imported could growth and flower Normally in experimental zone of Shanxi, but there are Significant differences on Growth, fruiting, and adaptability. The best species are hybridize3and hybridize4which are Vigorous growth, strong adaptability, while Brazil hongyun imported is poorerFruit quality:the large seabuckthorn imported maintains the excellent properties such as fruit large, harvest easily. As the tree is young and the amount of bearingfruit is less, yield of hybridize3and hybridize4is high Compared with Chinese sea-buckthorn. From the perspective of the bioactive substances of fruits, bioactive substances of fruit contains in different species of seabuckthorn exist difference, and vitamin C and flavonoids content of seabuckthorn imported are lower than Chinese seabuckthornTwig cuttings:Cutting period, seabuckthorn varieties, substratum, exogenous hormones cuttings have important effect on survival rate of Twig cutting, root growth and new shoots which is interpreted that success or failure of Seabuckthorn twig cuttings is not only influenced by its own genetic factor, but also related to a variety of external environmental factor.
