- 摘要:
- 以砂梨品种“湘南”为试材，连续2年(2013—2014年)对不同留果量影响果实生长发育动态和品质的变化规律进行了研究。结果表明：在贵州地区条件下，结果枝上不同留果量直接影响果实纵横径生长量在年生长过程中的生长高峰期次数和出现时间，生长高峰期有5～12次，纵径有6～8次，单个结果枝结果1、2、3、4、5、6个生长高峰期分别为6、6、6、8、7、7次；横径有5～12次，单个结果枝结果1、2、3、4、5、6个生长高峰期分别为6、5、9、10、12、6次。不同留果量直接影响果实纵横径日生长量在年生长过程中的生长高峰期次数和出现时间，生长高峰期有6～7次，纵径有6～8次，单个结果枝结果1、2、3、4、5、6个生长高峰期分别为8、7、7、6、7、7次；横径有6～8次，单个结果枝结果1、2、3、4、5、6个生长高峰期分别为8、7、7、7、6、7次。不同留果量直接影响砂梨果实的果形指数和果实品质等，综合效果以单条结果枝留2个果为最好，其次是单条结果枝留1个果，再次是单条结果枝留3个果，都优于其它处理。可见，“湘南”梨结果枝上不同留果量直接影响果实纵、横径的生长高峰次数、高峰出现的时间和生长曲线的起伏程度，也影响果实的单果重和质量。建议在“湘南”梨生产上把结果枝上留果量作为疏花疏果和果实品质变化的重要依据，为制定科学的砂梨栽培技术和管理措施提供参考。
- Abstract:
- Taking Chinese pear variety ‘Xiangnan’ as test materials， different retaining fruits on the influences of fruit growth dynamic and changing law were studied during continuous 2 years(2013—2014).The results showed that,the pear under the condition of Guizhou region，different retaining fruits directly affected the growth of the fruit vertical and horizontal diameter growth in years growth peak frequency and time，growth peak appeared 5-12 times，longitudinal diameter appeared 6-8 times，single fruit retaining 1，2，3，4，5，6 appeared growth peak 6，6，6，8，7，7 times respectively;Transverse diameter appeared 5-12 times，fruit retaining 1，2，3，4，5，6 appeared growth peak 6，5，9，10，12，6 times respectively.Different retaining fruit quantity directly affected the day growth of the fruit vertical and horizontal diameter increment in years growth peak frequency and time，in the process of growth peak had 6-7 times，longitudinal diameter had 6-8 times，retaining fruit 1，2，3，4，5，6 appeared 8，7，7，6，7，7 times respectively；Horizontal diameter had 6-8 times，retaining fruits 1，2，3，4，5，6 appeared growth pesk 8，7，7，7，6，7 times respectively.Different retaining fruit quantity directly affected Chinese pear fruit shape index and the fruit quality and so on，single branch retaining 2 fruits was comprehensively the best treatment，followed by was a single branch for 1 fruit，the third was single branch for 3 fruits，three treatments were all superior to other processing.It showed that different retaining fruits treatment directly affected the amount of longitudinal and transverse diameter of fruit growth peak，peak time and growth curve，also affected the weight and quality of the fruit.It suggested that fruit retaining should be taken as important reference for flower and fruit thinning and fruit quality change，to provide the reference for developing scientific pear cultivation techniques and management measures.
