在不同水分条件下,对花生茎节茸毛的密度和长度及其与抗旱性关系进行初步研究。结果表明,在不同水分条件下,17个品种中,茸毛密度只有6个品种变化不规律;基部节位茸毛密度易发生变化,中上部节位茸毛密度级别较平稳,且与抗旱性有关,在密度各级别中都有抗旱性强的品种,但在抗旱性差的品种中未发现有密度大的。茸毛长度的变化,在水分胁迫条件下比在田间条件下茸毛变短,且呈显著的正相关,但茸毛长度与抗旱性、密度均无明显关系。
Under different water conditions, the relationship between the density and length of the antler hairs of peanut and their relationship with drought resistance was studied. The results showed that under different water conditions, there were only irregular variations of hairs density in 17 cultivars. The densities of hairs were more likely to change in the proximal node, while the vellus density in the upper and middle nodes was more stable and related to drought resistance. Drought resistant varieties were found at all levels of density, but no significant density was found in the varieties with poor drought resistance. The change of the length of velvet hair was shorter and shorter than that under the condition of water stress, but there was a significant positive correlation between the length of the hair and the drought resistance and density.
