摘  要:
以蓝果忍冬5个种("阿尔泰忍冬"、"勘察加忍冬"、"巴利斯忍冬"、"蓝靛果忍冬"、"博奇卡勒尼卡娃忍冬")和1个品种("EYL-1")的2a生扦插苗为试材,研究不同空气湿度处理对蓝果忍冬株高、相对生长量和外部形态的影响,以期为蓝果忍冬的驯化栽培提供理论依据。结果表明:空气湿度不仅影响蓝果忍冬的生长发育,而且对外部形态也有显著影响。在RH 75%处理下,蓝果忍冬生长良好,随着空气湿度的下降,植株株高及相对生长量呈下降趋势,"勘察加忍冬"在各相对湿度处理下的相对生长量均是最小。在RH45%处理20d后,"勘察加忍冬"、"博奇卡勒尼卡娃忍冬"、"蓝靛果忍冬"叶片部分出现萎蔫、下垂、失去光泽、甚至脱落,而"阿尔泰忍冬"在低空气湿度下表现良好,可作为优良育种材料。

摘  要:
In order to provide theoretical basis for domestication cultivation of blue honeysuckle,2 years old cuttings of five species(L.altaicai,L.kamtschatica,L.pallasii,L.edulis,L.boczkarni-kowii) and one variety(‘EYL-1’) were taken as materials to research effect of different relative humidity on height,relative growth,and morphology of blue honeysuckle.The results showed that Air humidity not only affected the growth and development of blue honeysuckle,but also on the morphology.Blue honeysuckle grew well at RH75% treatment,the height of blue honeysuckle and relative growth decreased with the decline of air humidity.The relative growth of L.kamtschatica was smallest at any treatment.Some leaves of L.kamtschatica,L.boczkarnikowii and L.edulis were wilting,drooping and tarnish,even fell off on 20th day after at RH45% treatment,while L.altaicai,growth well at low air humidity,indicated that L.altaicai,was a good breeding material.
