不同PBO处理对‘望山红’生长、生理特性和果实品质的影响

本文以8年生‘望山红’（‘长富2’芽变）苹果树为试材,在6月初及6月中旬喷施不同浓度的PBO药剂,喷清水为对照,通过测量枝类组成、光合特性、叶绿素和果实品质等指标,研究不同PBO处理对‘望山红’生长、生理特性和果实品质的影响。结果表明,‘望山红’连续2年喷施PBO后,各处理极显著的增加了中短果枝的比例,降低长枝比例;且各处理的净光合速率、气孔导度和蒸腾速率均高于CK,胞间CO2浓度随着净光合速率的增大而减小;各处理的叶绿素a、叶绿素b和叶绿素a＋b都极显著高于CK;各处理的单果重、可溶性固形物、可溶性总糖和糖酸比显著高于CK,但硬度、果形指数和可滴定酸含量与CK间差异不显著。在6月初和6月中旬...

Summary:本文以8年生‘望山红’（‘长富2’芽变）苹果树为试材,在6月初及6月中旬喷施不同浓度的PBO药剂,喷清水为对照,通过测量枝类组成、光合特性、叶绿素和果实品质等指标,研究不同PBO处理对‘望山红’生长、生理特性和果实品质的影响。结果表明,‘望山红’连续2年喷施PBO后,各处理极显著的增加了中短果枝的比例,降低长枝比例;且各处理的净光合速率、气孔导度和蒸腾速率均高于CK,胞间CO2浓度随着净光合速率的增大而减小;各处理的叶绿素a、叶绿素b和叶绿素a＋b都极显著高于CK;各处理的单果重、可溶性固形物、可溶性总糖和糖酸比显著高于CK,但硬度、果形指数和可滴定酸含量与CK间差异不显著。在6月初和6月中旬分别喷施PBO 100倍处理,可以提高‘望山红’的光合速率,改善其光合性能、树势和果实的品质。

In this paper,8 years‘Wangshanhong＇（bud sport of‘Nagafu 2＇） apple trees were used as tested materials,which were sprayed by PBO with different concentrations in early and mid June,and clean water was sprayed as control. Effects of different PBO treatments on growth,physiological characteristics and fruit quality of‘Wangshanhong＇by measuring the composition of branches,photosynthetic characteristics,chlorophyll and fruit quality and so on were studied. The result showed that every treatment of PBO significantly increased the proportion of middle and short branches of‘Wangshanhong＇and reduced the proportion of its long branches in two consecutive years. The net photosynthetic rate,stomatal conductance and transpiration rate of different PBO treatments were higher than those of control,and intercellular CO2 concentration decreased with the increase of net photosynthetic rate of each treatment; Chlorophyll a,chlorophyll b a
