Comparative study on cold resistance and drought tolerance of different grape rootstocks
摘要
Abstract
[Objective]With the new situation of climate change,further selection of grape rootstock varieties suitable for cold re-sistance and drought tolerance in the Northwest China is necessary to provide theoretical basis and technical support for the un-buried cultivation of grapes.[Methods]Thirteen-year-old grape rootstock varieties including 41Bmgt,Riparia,420Bmgt,101-14,196-17,44-53ma,110R,Rupestris du Lot,SO4,161-490,1103P,5BB,3309,and Leon Millt,were selected as test materials.The cumulative water loss rate of isolated one-year-old shoots was measured,and combined with field investigation of grape rootstock survival rate and drying rate of isolated one-year-old shoots,the drought resistance of different grape root-stock varieties was evaluated.A high and low temperature alternation test chamber was used to simulate low temperatures,with temperature gradients set at 4℃(control),-15℃,-20℃,-25℃,and-30℃.Physiological and biochemical indica-tors including relative conductivity,malondialdehyde,free proline,soluble sugars,and soluble proteins of different grape root-stock one-year-old shoots were measured,and the cold resistance of different grape rootstocks was comprehensively evaluated using the subordinate function method.[Results]The drought resistance of different grape rootstocks from strongest to weakest was as follows:3309>161-490>196-17>Leon Millt>420Bmgt>44-53ma>Riparia>110R>1103P>SO4>101-14>41Bmgt>5BB>Rupestris du Lot;As the treatment temperature decreased,the cold resistance indexes of different grape root-stock shoots generally increased,but there were differences among different varieties.According to the comprehensive analysis of the affiliation function,the cold resistance of grape rootstocks from strongest to weakest was as follows:SO4>196-17>Le-on Millt>5BB>Riparia>44-53ma>420Bmgt>1103P>3309>110R>Rupestris du Lot>101-14>41Bmgt>161-490.[Conclusion]Riparia,196-17,44-53ma,and Leon Millt have strong drought resistance and cold resistance and can be used as unburied grape rootstocks in the north-west region of the country.关键词
