摘要: 摘 要本试验以同源四倍体玫瑰香葡萄和其二倍体玫瑰香母株以及贝达、巨峰和Dog Ridge的硬枝插条为试材,采用自动控温插床扦插。定期调查了硬枝插条的不定根发生率、发生数量和长度,一级侧根数量和长度等,结果表明:玫瑰香葡萄同源加倍以后,其硬枝扦插的不定根发生时期推迟了3d,且不定根发生率、不定根发生数量和不定根生长量显著降低。扦插第21d,同源四倍体玫瑰香的不定根发生率、不定根发生数量和不定根平均生长量分别只有22.6%、0.52条/插条和1.6cm,显著低于同期二倍体玫瑰香母株的不定根发生率、不定根发生数量和不定根平均生长量(分别达为58.8%,3.27条/插条和14.6cm)。

Abstract: Abstract: Morphology of adventitious root formation in hardwood cuttings of Autotetraploid Grape Muscat Hamburg was studied. The cuttages of Autotetraploid Grape Muscat Hamburg, diploid Grape Muscat Hamburg, Bate, Kyoho Grape and Dog Ridge were used as materials in this paper. The cutting was carried in automatic temperature control cutting bed. The rooting rate, the root number and root length per cottage, and the number and length of lateral roots per primary root were investigated termly. The results indicated that the date of adventitious root emerge of Autotetraploid Grape Muscat Hamburg was postponed 3d in hardwood cutting. The rooting rate, the root number and the root growth per cuttage decreased remarkably. After cutting 21d, The rooting rate, the root number and the root length per cuttage were 22.6%, 0.52, and 1.6cm respectively. They were significantly lower than diploid Grape Muscat Hamburg, whose rooting rate, root number and root length per cuttage were 58.8%, 3.27 and 14.6cm respectively.
