摘要
以‘维多利亚’、‘早黑宝’、‘红地球’、‘丽红宝’、‘紫提988’、‘京亚’的一年生硬枝为材料,选用配比为1∶1∶1的草炭、蛭石、珍珠岩作扦插基质,进行硬枝扦插。通过观察在日光温室大棚下六个品种的生根情况,对扦插后枝条的萌芽时间、单株叶片数量、生根初始期、生根数量、根长、根粗、成活率等指标进行观测和分析。结果表明,不同品种间的遗传差异对葡萄硬枝扦插不定根的发生有显著影响。其中‘紫提988’的成活率最高为76.7%,显著高于除‘维多利亚’外的其它品种;‘维多利亚’的平均根长最长,达15.6 cm,显著高于‘京亚’;‘早黑宝’的平均根粗最粗,达2.3 mm,显著高于‘丽红宝’和‘京亚’;综合评价六个品种的扦插效果由高到低依次为:‘维多利亚’>‘紫提988’>‘早黑宝’>‘红地球’>‘丽红宝’>‘京亚’。本试验为优良鲜食葡萄品种的苗木扦插繁育提供了参考。
In this research,one-year-old branches of‘Victoria’,‘Zaoheibao’,‘Red Globe’,‘Lihongbao’,‘Ziti988’and‘Jingya’were used as hardwood cuttings to observe and analyse the sprouting time,leaf qualities,initial rooting period,rooting qualities,root length,root rough and survival rates in sunlight greenhouse.Culture medium contained peat,vermiculite and perlite,with a volume ratio of 1∶1∶1.The results showed that the genetic difference among cultivars affected adventitious root formation significantly.The survival rates of‘Ziti988’were the highest(76.7%),significantly higher than any other species except‘Victoria’;the root length of‘Victoria’were the highest(15.6 cm),significantly higher than‘Jingya’;the root thickness of‘Zaoheibao’were the highest(2.3 mm),significantly higher than‘Lihongbao’and‘Jingya’;In sequence,the cuttage effects of six grape varieties were‘Victoria’>‘Ziti988’>‘Lihongbao’>‘Zaoheibao’>‘Red Globe’>‘Jingya’.
