Abstract

Soil drought and salinization limit grape production, and the cultivation of salt and drought resistant table grape varieties can effectively solve this problem. In this study, the salt and drought tolerance of 20 table grape varieties was comprehensively evaluated by different methods. Under salt and drought stress the growth of grapes was inhibited; the stomatal resistance, relative conductivity, MDA, FRAP antioxidant activity, ABA, ABS/RC, TRo/RC, and DIo/RC in leaves increased; and the relative water content, content of photosynthetic pigments, Fv/Fm, PI abs, and ETo/RC in leaves decreased. The degree of damage was greatest under combined salt-drought stress, followed by sole salt stress and sole drought stress. Under various stress conditions, 'Munage' exhibited strong tolerance. Compared with the sensitive variety 'Sweet sapphire', the new shoot growth quantity and Fv/Fm of 'Munage' were respectively 146.67 % and 10.88 % higher under salt stress, 93.10 % and 3.63 % higher under drought stress, and 200.00 % and 13.31 % higher under combined stress. Correlations between indicators were observed, the shoot growth, stomatal resistance, Chla and chlorophyll fluorescence parameters of leaves could be used as reliable indicators for rapidly evaluating the salt and drought tolerance of grapes. Membership function analysis and principal component analysis were used to calculate the D-value (the comprehensive evaluation indicator). 'Munage', 'Manaizi', 'Thompson Seedless', and 'Hotan Red' were highly salt and drought-tolerant varieties. 'Kyoho', 'Red muscatel', 'Summer Black', 'Shine Muscat', and 'Sweet sapphire' were highly sensitive to salt and drought. Three stepwise regression models were also developed for the rapid screening and identification of salt and drought-tolerant grape varieties. In conclusion, key salt and drought tolerance indicators and comprehensive evaluation methods were proposed to identify salt and drought-tolerant grape varieties.

20个鲜食葡萄品种对单一和复合盐干旱胁迫的综合评价及生理响应。

土壤干旱和盐碱化限制了葡萄的生产，种植耐盐抗旱的鲜食葡萄品种可以有效地解决这一问题。本研究采用不同方法对20个鲜食葡萄品种的耐盐性和耐旱性进行了综合评价。盐胁迫和干旱胁迫抑制了葡萄的生长；叶片气孔阻力、相对电导率、MDA、FRAP抗氧化活性、ABA、ABS/RC、TRo/RC和DIo/RC均增加；叶片相对含水量、光合色素含量、Fv/Fm、PI / abs和ETo/RC均降低。盐-干旱复合胁迫下的损害程度最大，其次是单一盐胁迫和单一干旱胁迫。在各种压力条件下，“Munage”表现出很强的耐受性。与敏感品种‘甜蓝宝石’相比，盐胁迫下‘芒纳奇’的新梢生长量和Fv/Fm分别提高了146.67%和10.88%，干旱胁迫下分别提高了93.10%和3.63%，复合胁迫下分别提高了200.00%和13.31%。结果表明，茎部生长、气孔抗性、叶片Chla和叶绿素荧光参数可作为快速评价葡萄抗旱性和耐盐性的可靠指标。采用隶属函数分析和主成分分析计算d值（综合评价指标）。‘Munage’、‘Manaizi’、‘Thompson无籽’和‘和田红’是高度耐盐耐旱的品种。‘Kyoho’、‘Red muscatel’、‘Summer Black’、‘Shine muscatel’和‘Sweet sapphire’对盐和干旱高度敏感。建立了3个逐步回归模型，用于耐盐耐旱葡萄品种的快速筛选和鉴定。综上所述，提出了耐盐耐旱葡萄品种鉴定的关键指标和综合评价方法。

期刊介绍： Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment. Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
