ABSTRACT Grape is intolerant of aluminum. This intolerance leads to severe aluminum poisoning when the plants are cultivated in acidic soil, resulting in a decline in their yield and quality. To reduce and prevent the dangers of aluminum toxicity to grape, a method of identifying tolerance to aluminum was discussed, and genotypes tolerant to aluminum were screened. Twenty-six grape germplasm resources from different sources were used as materials. The morphological and physiological indices in different germplasm sources grown in soilless cultivation and subjected to aluminum stress were measured and compared to a control. The coefficient for the tolerance to aluminum of each character was used as the index of aluminum tolerance. The principal component analysis method was used to combine 13 individual indices into five independent comprehensive indices, which could represent 85.341% of the original data on the tolerance of the plants to aluminum. Through cluster analysis, the 26 grape germplasm sources were divided into three types. Vitis vinifera ‘Red Globe’, V. vinifera ‘Blackcurrant’, (V. amurensis × V. vinifera)×V. amurensis ‘Zuoyouhong’ and V. sinocinerea were tolerant to aluminum. Twelve genotypes were moderately tolerant to aluminum and ten genotypes were intolerant to aluminum. Four indices with significant effects on the tolerance to aluminum were screened out, including the fresh weight of the aboveground vegetation and the malondialdehyde (MDA), H2O2 and proline contents, which could be used as the identified index of the tolerance to aluminum in grape. The comprehensive evaluation of the tolerance of grape to aluminum using these methods can avoid the one-sidedness and instability of a single index, and the result is more reliable.

葡萄耐铝基因型筛选及筛选指标评价

摘要 葡萄不耐铝。当植物在酸性土壤中栽培时，这种不耐受性会导致严重的铝中毒，从而导致其产量和质量下降。为减少和预防铝中毒对葡萄的危害，探讨了鉴别铝耐受性的方法，并筛选了耐受铝的基因型。以不同来源的26种葡萄种质资源为材料。测量了在无土栽培中生长并受到铝胁迫的不同种质来源的形态和生理指标，并与对照进行比较。以各性状的耐铝系数作为耐铝指标。采用主成分分析法将13个单项指标组合成5个独立的综合指标，可代表植物对铝耐受性原始数据的85.341%。通过聚类分析，将26份葡萄种质资源分为三类。Vitis vinifera 'Red Globe', V. vinifera 'Blackcurrant', (V. amurensis × V. vinifera)×V. amurensis '左油红'和 V. sinocinerea 对铝具有耐受性。12 种基因型对铝具有中等耐受性，10 种基因型对铝不耐受。筛选出4个对铝耐受性有显着影响的指标，包括地上植被鲜重和丙二醛(MDA)、H2O2和脯氨酸含量，可作为葡萄耐铝性的鉴别指标。
