Abstract
一种抗虫速生杨的新品种是由基因枪把抗虫基因植入杨树，内含芸金芽孢杆菌(Bacillus thuringiensis)，一种能在细胞内形成菱形，伴孢晶体内芽孢杆菌，伴孢菌晶体是一种毒性很强的蛋白质结晶，能毒害昆虫的肠道而使之瘫痪致死，对人、畜无害，芽孢也能在虫体内萌发繁殖，从而加速昆虫死亡，树杆表皮有腊质，将20～30厘米长，直径在1～2厘米的枝条，沾蜂蜜扦插或组织培养等方法无性繁殖。
Description
一种抗虫速生杨树新品种涉及到生物工程技术领域，属于速生树种Populus L.杨属(杨柳科)Poplar，Aspen，Cottonweed植物，落叶乔木，叶常宽阔。花单性，雌雄异株，柔荑花序，苞片边缘常有剪碎状裂片，无花被，有杯状花盘，雄蕊常多数，种子有毛，生长在沙荒、轻碱土均可生长，喜光，根系发达，能固沙，护土，木材轻软，供造纸、板料、家具等用材，又为观赏树，树叶可做饲料，我国约有50种，常见如披针叶杨、响叶杨、阿拉善杨、黑龙江杨、狭叶杨、脂杨、欧洲大叶杨、青杨、缘毛杨、山杨(火杨)、三角杨(美洲黑杨)、胡杨(胡桐)、二白杨(青白杨，甘肃杨)、东北杨(吉林杨)、灰背杨、大齿杨、德钦杨、河北杨(椴杨)、兴安杨、伊犁杨、康定杨、香杨(朝鲜杨)大叶杨、苦杨、米林杨、热河杨、辽杨(马氏杨)、玉泉杨、黑杨(欧洲黑杨)、钻天杨(笔杨，美国白杨)、箭杆杨、汉白杨(宁陕杨)、帕米尔杨、柔毛杨、灰胡杨、青甘杨、梧桐杨、小青杨、长序杨、冬瓜杨(太白杨，水冬瓜)、昌都杨、青毛杨、小叶杨(南京白杨)、塔形小叶杨(扫帚小叶杨)、垂枝小叶杨、甜杨、四川杨、密叶杨、毛白杨(大叶杨，响叶子杨)、抱头毛白杨、欧洲山杨、三脉杨、大青杨、堇柄杨、椅杨(魏氏杨)、长叶杨、北京杨、中东杨、加杨(欧美杨)、尤金杨、格尔里杨、意大利214杨、菜比锡杨、波兰15号杨、新生杨、健杨、沙兰杨、晚花杨、额河杨、响毛杨、小黑杨、小钻杨、亚东杨、五瓣杨、滇杨(云南白杨)、美荷速生杨等。
由于近几年外来生物舞毒蛾的侵入对常规杨树种遭到非常严重的危害，个别严重的地区杨树叶被舞毒蛾幼虫基本吃光，现有的杨树抗虫转基因植株培育技术对舞毒哦的杀虫死亡率仅在50％以上，经过多代繁殖过程中，无性系的芽变异出优良新品种，抗虫效果增加了20％以上等特别好的效果。
一种抗虫速生杨的新品种是用基因枪把抗虫基因植入杨树，内含苏芸金芽孢杆菌(Bacillus thuringiensis)一种能在细胞内形成菱形，伴孢晶体的芽孢杆菌，伴孢菌晶体是一种毒性很强的蛋白质结晶，能毒害昆虫的肠道而使之瘫痪致死，对人、畜无害，芽孢也能在虫体内萌发繁殖，从而加速昆虫死亡，对舞毒蛾的杀虫死亡率高达70％以上，二年生胸经达15-18厘米以上，基本上不会发生舞毒蛾等虫害，生长速度特别快，超过杨柳科任何植物及全世界生长最快的奇迹树——Roxb.，Samena cadamba(Roxb.O.Ktze)大叶黄梁木(团花，黄梁木)Chines Anthocephalus，叶片大15平方厘米以上，直杆，树杆表皮有腊质。
一种抗虫速生杨的新品种的繁殖实施方法是：将20～30厘米长，直径在1～2厘料的枝条，沾蜂蜜扦插或组织培养等方法无性繁殖。
