- 摘要:
- 以20份苹果砧木种质资源和相同的接穗品种为试材，采用统一嫁接后测定叶部营养与表型性状、光合性能及根际土壤养分的方法，研究了不同砧木在盐碱田间的生理生态适应性及其与土壤因子的关联，以期为培育耐盐碱的优良砧木提供参考依据。结果表明：在pH 7.68~8.65、全盐0.36%~0.81%的盐碱田间，果树性能方面各指标差异系数在8.98%~26.27%，砧木间果树性能与根际土壤指标的平均差异系数分别为16.01%和15.40%，其中叶面积、净光合速率、土壤全盐及碱解氮等指标变异显著（差异系数>15%）；相关性分析表明，叶部表型与土壤碱解氮、全钾呈正相关（P＜0.05），光合性能与土壤pH（P＜0.05）及碱解氮（P＜0.01）显著相关。综合评估筛选出耐盐碱性最优的3份砧木为GM256、D8和D11。
- Abstract:
- Taking 20 apple rootstock germplasm resources and the same scion variety as test materials,by employing a uniform grafting method followed by measurements of leaf nutrition and phenotypic traits，photosynthetic performance，and rhizosphere soil nutrients，the physiological and ecological adaptability of different rootstocks in saline-alkaline field conditions and their associations with soil factors were investigated，in order to provide a reference for the cultivation of excellent rootstocks for saline-alkali land.The results showed that in the saline-alkaline field (pH 7.68-8.65;total salt,0.36%-0.81%)，the coefficients of variation for various fruit tree performance indicators ranged between 8.98% and 26.27%，with average coefficients of variation for fruit tree performance and rhizosphere soil indicators being 16.01% and 15.40%，respectively.Indicators such as leaf area，net photosynthetic rate，soil total salt，and alkali-hydrolyzable nitrogen exhibited significant variation (coefficient of variation>15.00%).Correlation analysis revealed that leaf phenotypic traits were positively correlated with soil alkali-hydrolyzable nitrogen and total potassium (P<0.05)，while photosynthetic performance was significantly correlated with soil pH (P<0.05) and alkali-hydrolyzable nitrogen (P<0.01).Comprehensive evaluation identified three rootstocks with optimal salt-alkaline tolerance were GM256，D8，and D11.
