摘要
四倍体刺槐Robinia pseudoacucia自1 997年引入我国以来,国内学者对其主要进行了如下几个方面的研究:1)不同地城不同立地条件下的适应性、生物量厦叶片营养含量,肯定了饲料型四倍体刺槐的引种价值。2)常规和微繁育苗技术:常规育苗技术中的插根和嫁接繁殖技术已经成熟,达到了规模化生产的要求,微繁技术已找到了愈伤组织诱导厦其分化为苗的培养基组合和培养条件以厦组培苗的适宜移栽方式。3)抗盐基因遗传转化;已成功地将甜菜碱醛脱氢酶基因(BADH)转入四倍体刺槐,得到了15个抗盐植株.抗盐植株时NaCI的相时抗性提高了2‰~3‰。从引种、造林、微体快繁技术和遗传转化4个方面综述了这些研究成果,并探讨了存在的问题厦可能的解决方法。
The research mainly focused on the following aspects since tetraploid black locusts had beenintroduced to China in 1997: 1) The adaptability in different regions, biomass and leaf nutrient content, the introduction value was further testified; 2) Traditional and biotechnological reproductiontechniques successfully applied; 3) Salt-tolerance of BADH transgenic plants increased 2‰-3‰. Theresearch progress in introduction, afforestation, micro-propagation and transformation was summarized and some solutions to exiting problems were discussed.
