不同品种黑莓果实发育过程中硬度变化规律的调查与分析
Changes in Fruit Firmness of Different Blackberry Cultivars during Development and Ripening
摘要
Abstract
From the 3rd day after flowering (DAF) to the maturation, the fruit ripening condition and changes in fruit firmness of five blackberry cultivars (Kiowa, Arapaho, Boysen, Chester and Hull) were investigated. The results showed these five cultivars had distinct reproductive stages during fruit development and maturation. However, they all began to form small aggregate fruit on 9 DAF, and Kiowa had the highest (7.34 lb/mm2) firmness value and the other four showed little difference. During fruit development and ripening, fruit firmness of Kiowa and Boysen both showed the trend of rapid decline at their initial maturation stage (36 ~39 DAF and 21 ~24 DAF, respectively). At full maturation stage, fruit firmness value of these two cultivars was both 0 lb/mm2. Differently, the dynamic changes in the fruit firmness of Chester and Arapaho were similar in the fruit development and maturation process. Their firmness value both reached maximum and then declined and kept stable after that with final rapid decrease. At full maturation stage, Chester had the highest firmness value (2.69 lb/mm ) among five blackberry cultivars. Fruit firmness of Hull showed a whole dynamic trend of increase - decrease - increase - decrease. These results provided basis for further revealing fruit ripening and softening mechanism and regulation of blackberry cultivars with different firmness trait.关键词
