摘要: 山葡萄种质2413为75—2-200(通化3号×双庆)植株的一个枝蔓变异的自然授粉后代。对
2413及75-2-200进行了形态学、组织学、孢粉学、细胞学鉴定。结果表明,2413叶片大而厚,叶柄和枝条粗壮,节间长,气孔大,花粉粒大,花粉发芽率低,体细胞染色体2n:76,证明其为四倍体。

关键词: 葡萄, 山葡萄, 四倍体, 鉴定

Abstract: The 2413 was an open pollination hybrid progeny germplasm that derived from branch variance in
diploid euhivars 75—2—200,which were found from the hybridization between diploid euhivars‘1'ong}nla 3’and
‘Shuangqing’. Morphologie and histology characteristics of the 24 13 gennplasm an d cytology identification of the
root apex were studied in comparison with that of diploid gennplasm 75—2—200.Results showed that 24 13 germplasm
had larger and thicker leaf, stronger petiole and branch, larger stomata size, smaller stoma ta density, L~,'ger
pollen size,lower percentage of polen and chrolnosome number Was tetrapolid (2n:4x=76).It is,therefore,
tetraploid.
