摘要:

以大蒜(Allium sativum)‘伊宁红皮’和抽薹型分蘖洋葱(Allium cepa var. aggregatum)‘M-4’为试验材料,通过间作,分析分蘖洋葱对大蒜开花的影响。结果表明,分蘖洋葱与大蒜间作,可以显著提高大蒜植株生长势,平均株高和假茎粗分别为96.3 cm和10.6 mm,比对照分别增高6.1 cm,增粗2.4 mm。间作的分蘖洋葱可促进大蒜的生殖发育,抽薹期比对照提前4 d,功能性大蒜小花数增多,减少气生鳞茎的数和大小,而且上调花分生组织属性基因gaLFY和AsFUL的转录水平。抽薹型分蘖洋葱与大蒜间作具有促进大蒜功能花发育的化感效应,有利于实现大蒜育性恢复。

Abstract:

As a study of the allelopathy of multiplier onion(Allium cepa var. aggregatum)on the reproductive development in garlic(Allium sativum),‘Yining Hongpi’garlic and‘M-4’bolting multiplier onion were used to examine the effect on garlic flowering through mixed intercropping. The results showed that bolting multiplier onion significantly enhanced the growth potential of garlic. The mean plant height and pseudostem diameter were 96.3 cm and 10.6 mm respectively and increased significantly by 6.1 cm,2.4 mm compared with control group. Bolting multiplier onion promoted the reproductive development in garlic. The bolting time was advanced by 4 days under allelopathic treatment in comparison with the control group. The number of functional florets per inflorescence increased,meanwhile the number and size of topsets decreased. The transcriptional levels of the floral meristem identity genes gaLFY and AsFUL were up-regulated. Bolting multiplier onion had allelopathic effects on garlic by promoting the functional flower development to potentially restore fertility.
