| 摘 要： | 采用TTC法、孢粉染色法及联苯胺—过氧化氢法,从花粉活力、花粉可育性及柱头可授性方面研究了蒙古韭Alliummongolicum、碱韭A.polyrhizum和细叶韭A.tenuissi mum3种野生葱属植物的传粉生物学特征。结果表明:3种野生葱属植物的花粉活力和可育率均较高,分别为蒙古韭73.40%±2.94%,79.44%±2.83%;碱韭71.23%±4.39%,84.32%±1.63%;细叶韭80.62%±4.11%,70.93%±4.86%。三者花粉活力下降快,花粉寿命约为8 h,最佳传粉期为开花后3~4 h。三者的柱头均具较高的可授性,可授性持续5 d左右,最佳授粉期为2 d左右。

| Abstract: | TTC (2,3,5-triphenyl tetrazolium chloride) method, pollen staining method and Benzidine-H2O2 method were used to study the pollination characteristics of 3 wild species (Allium mongolicum, A. polyrhizum and A. tenuissimum) in terms of pollen viability, pollen fertility and stigma receptivity. The results showed that all the 3 plants had high pollen viability and pollen fertility. Pollen viabilities were 73.40%±2.94%, 71.23%±4.39% and 80.62%±4.11% for A.mongolicum, A. polyrhizum and A. tenuissimum, respectively, and the pollen fertilities were 79.44%±2.83%,84.32%±1.63 and 70.93%±4.86% respectively. The pollen viabilities decreased quickly and pollen longevities were about 8 hours for 3 plants. Optimal pollination time was 3 to 4 hours after flowering. The stigma receptivity of 3 plants was around 5 days. Optimal rpollination period lasted around 2 days. |
