为给筛选抗旱性强的油茶优良单株以选育油茶抗旱砧木提供参考依据，以香花油茶、小果油茶、普通油茶、陆川油茶、博白大果油茶和广宁红花油茶这6个油茶物种的1年生实生苗为试材，采用人工控制浇水使土壤自然干旱的方法对其抗旱性进行了试验研究，并对其苗期抗旱性的强弱进行了评价。结果表明：广宁红花油茶的暂时萎蔫系数和永久萎蔫系数分别达到5.09%和3.11%，均显著高于其它油茶物种；而香花油茶的暂时萎蔫系数和永久萎蔫系数均最小，仅分别为2.42%和1.10%；6个油茶物种的抗旱能力由强到弱依次为香花油茶＞小果油茶＞普通油茶＞陆川油茶＞博白大果油茶＞广宁红花油茶；6个物种内不同单株间的抗...

In order to select out some superior individuals with strong drought-resistance and to provide a reference for drought-resistance root stock breeding, taking one-year-old seedlings of six Camellia species as materials, including C. osmantha, C. meiocarpa, C. oleifera, C. vietnamensis, C. gigantocarpa and C. semiserrata, their drought resistance were reached and evaluated through the way of artiifcial control of irrigating to make soil naturally dry. The results show that:temporary wilting coefifcient and wilting coefifcient in C. semiserrata reach up to 5.09%and 3.11%respectively, which are si...
