摘要:

为筛选出抗旱能力较强的鲜食葡萄品种,研究了叶片解剖结构与鲜食葡萄品种抗旱能力之间的关系。以10个鲜食葡萄品种1年扦插苗为试验材料进行盆栽干旱胁迫,测定其生长势、叶片相对含水量和叶片解剖结构,并运用主成分分析法对各鲜食葡萄品种的抗旱能力进行综合评价。结果表明,干旱胁迫导致10个鲜食葡萄品种的旱害症状呈现不同程度增加,叶片相对含水量呈现大幅度的下降,将各抗旱相关指标对干旱胁迫的敏感程度依据抗旱系数进行排序,依次为栅海比>细胞紧实度>栅栏组织厚度>下表皮厚度>叶片厚度>茎节粗度=新梢长度>上表皮厚度=茎节长度>细胞疏松度>海绵组织厚度>叶片宽度>叶片长度。进一步通过主成分分析法得出,10个鲜食葡萄品种的抗旱能力大小依次为‘黑脆无核’>‘阳光玫瑰’>‘深红玫瑰’>‘火焰无核’>‘户太8号’>‘夏黑’>‘浪漫红颜’>‘紫甜无核’>‘丝路红玫瑰’>‘甜蜜蓝宝石’。研究结果可为我国干旱和半干旱地区鲜食葡萄的品种引进和进一步推广提供科学参考。

Abstract:

In order to screen out table grape varieties with strong drought resistance, the relationship between leaf anatomical structure and drought resistance of table grape varieties was studied. 10 cuttings of one-year-old table grape varieties were used as test materials for potted drought stress. Its growth vigor, leaf relative water content and leaf anatomical structure were measured, and drought resistance of table grape varieties was comprehensively evaluated by principal component analysis. The results showed that with the deepening of drought stress, the drought symptoms increased but relative water content decreased significantly in leaves of 10 grape varieties. According to the drought coefficient, the sensitivity of each drought resistance related index to drought stress was sorted, and the order was palisade tissue and spongy tissue ratio > cell tightness ratio > thickness of palisade tissue > thickness of lower epidermis > leaf thickness > stem diameter = shoot length > thickness of upper epidermis = stem length = spongy ratio > thickness of spongy tissue > leaf width > leaf length. Further through principal component analysis, the drought resistance ability of 10 table grape varieties were‘Blackcrunchy Seedless’>‘Sunshine Muscat’ >‘Crimson Rose’ >‘Flame Seedless’ >‘Hutai 8’ > ‘Summer Black’ > ‘Wagamichi’> ‘Zitian Seedless’> ‘Silk Road Red Rose’ > ‘Sweet Sapphire’. The results would provided scientific reference for the introduction and further promotion of table grape varieties in arid and semi-arid regions of China.
