  1. In this study, the stem segments of new shoot with axillary buds of well - growth tetraploid black locust trees were used as explants. the effects of different basic mediums, different hormone kinds and their concentrations ratios, different sucrose concentrations on calli induction, buds differentiation and rooting in the process of establishment of high frequency regeneration system of tetraploid black locust were studied. on the base of high frequency regeneration system, the effects of various factors on transformation efficiency of badh mediated by agrobacterium tumefaciens were discussed in the light of gus histochemical assays

    本實驗首先以生長良好的四倍體刺槐優株上當年生新梢的帶腋芽莖段為外植體,研究了在四倍體刺槐高頻再生體系的建立過程中不同基本培養基、不同激素濃度及其配比、不同蔗糖濃度對愈傷組織的誘導、芽的分化及生根的影響;然後在得到高頻再生體系的基礎上,通過農桿菌介導法轉化甜菜堿醛脫氫酶( badh )基因,以gus染色組織分析為依據探討了影響轉化效率的各種因素,建立了高效、可重復的基因轉化體系,為四倍體刺槐目的基因的導入打下了基礎。
  2. Fine - root dynamics in mixed plantation of poplar and black locust

    沙地楊樹刺槐混交林細根動態
  3. Tetraploid black locust is a variety has been bred in south korea, the leaves of which are 3 times larger than those of diploid varieties and contain 1. 4 times more protein. and it has no prickles on its surface. it can be used not only as pioneer species in environmental beautifying and ecological restoration, also as fodder, bee forage, timber production, and so on

    四倍體刺槐是韓國培育出的刺槐新品種,屬無刺類型,其葉片大小為普通二倍體刺槐的4倍,蛋白質含量為1 . 4倍多,不但可以作為先鋒樹種廣泛應用於環境美化和生態建設中,還可作為飼料、蜜源和木材等不僅具有較好的生態效益,同時還具有很高的經濟價值。
  4. According to reference, this research is the first time to transfer practically productive aim - gene to tetraploid black locust, and it is also the first time to transfer badh gene to forest - tree. this research provide a useful way in improving resistance to soline - alkali and drought of forest tree

    據資料檢索,該研究屬首次將具有生產意義的目的基因導入四倍體刺槐,也是首次將甜菜堿醛脫氫酶基因導入林木樹種,在培育耐鹽抗旱型林木品種方面進行了有益的探索。
  5. In this research project, the agrobacterium tumefaciens mediated transformation of badh gene of tetraploid black locust has been studied, for the purpose of improving resistance to soline - alkali and drought of tetraploid black locust ; of playing more important role in developing of waste lands, ameliorating of soline - alkali soil, and greening and beautifying of surface - mined lands, mine waste dumps, slopes of roads and railroads where restoration of vegetative cover has proven difficult ; of fully making benefits of its ability to fix atmospheric nitrogen in the soil

    為了進一步提高四倍體刺槐的耐鹽性和抗旱性,進一步擴大其適宜種植的生態范圍,充分發揮其固氮、改良土壤的特性,在我國的城鎮綠化、荒山造林、鹽堿地改良以及采礦跡地、公路、鐵路邊坡等植物生長困難土地的植被恢復中發揮其優勢,本實驗對四倍體刺槐進行了農桿菌介導的甜菜堿醛脫氫酶基因轉化的研究。
