不同生长调节剂处理对'龙丰'苹果生长、品质及产量的影响
Effects of Different Growth Regulators on the Growth,Quality and Yield of 'Longfeng'Apple
摘要
Abstract
In order to improve the quality and yield of'Longfeng'apples,with'Longfeng'apple as the experimental material,five representative growth regulators treatments were set up,which were Youdeli(T1),Ruisijia(T2),Benzamine Gibberellic Acid(T3),24-epibrassinolide lactone(T4),and amino acid containing water-soluble fertilizer(T5),and sprayed with clear water as the contrast(CK),spray once at the bud stage,young fruit stage and fruit expansion stage respectively to study the effects of different chemical treatments on the growth of apple trees and fruit quality and yield,so as to provide basis for improving the quality and yield of'Longfeng'apples.The results showed that,T2,T3,T4 and T5 all promoted the increase of leaf dry weight,fresh weight and new shoot thickness,T2 and T4 promoted the extension of new shoot length,and T1 had a certain effect on the increase of new shoot length and diameter.The fruit size of'Longfeng'apple could be increased by five treatments,but none of them reached significant level;All treatments increased the VC content of'Longfeng'apple fruit,T1,T4 and T5 increased the pH and solid acid ratio,decreased the titratable acid content,T1,T2,T3 and T5 increased the content of soluble solids,and T2 treatment also significantly increased the pH,only T1 increased the sugar acid ratio,T3 increased the content of soluble sugar,T5 increased the hardness.The yield per plant of'Longfeng'apple treated with five treatments were higher than that of the control,among which T2,T4 and T5 treatments were significantly higher than the control.Although the yield per plant of T1 and T3 were higher than that of the control,but there was no significant difference.The results of principal component analysis and comprehensive evaluation analysis showed that T1 was the best,followed by T4.To sum up,each treatment had promoted the growth of'Longfeng'apple tree in varying degrees,increased the fruit size of apple,improved the quality of fruit,and increased the yield of'Longfeng'apple per plant.关键词
