摘要
摘要:以富士苹果为研究对象,研究了夏剪枝时间对苹果果实品质、收获时和冷藏3.5个月后果实色泽和功能性状的影响。评价的处理包括12月、1月和2月的对照(不进行夏修剪)和夏修剪。夏季修剪晚于夏季修剪,果皮红色超过50%的果实比例比夏季修剪早于夏季修剪高出20.5%。总的来说,1月和2月的夏季修剪在2017/18季节提供了较高的花青素含量(分别为19和25.1 mg氰化3-糖苷·100 g -1 FW),总酚类化合物含量(分别为370.1和438.7 mg EAG·100 g -1 FW)和2,2-二苯基-1-苦味酰肼(DPPH)法测定的总抗氧化活性(分别为8,097.5和8,089.2µMol Trolox·100 g -1 FW)。夏修剪对冷藏后果实品质无影响。1月或2月进行夏修剪,可提高功能性化合物含量,改善红色;2月进行夏修剪,可提高果肉紧致度。
Late summer pruning improves the quality and increases the content of functional compounds in Fuji apples
: The objective of this paper was to evaluate the effect of the time of summer pruning on the quality of Fuji apples, on the red color and functional properties, at harvest and after 3.5 months of cold storage. The treatments evaluated consisted of the control (without summer pruning) and summer pruning in December, January, and February. The percentage of fruit with more than 50% red color on the skin was 20.5% higher when summer pruning was performed later than when performed early. In general, summer pruning in January and February provided fruit with a relatively high content of anthocyanins (19 and 25.1 mg cyaniding 3-glycoside · 100 g -1 FW, respectively), relatively high values of total phenolic compounds (370.1 and 438.7 mg EAG · 100 g -1 FW, respectively) and total antioxidant activity by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method (8,097.5 and 8,089.2 µMol Trolox · 100 g -1 FW, respectively) in the 2017/18 season. Summer pruning did not affect fruit quality after cold storage. Summer pruning performed in January or February increased functional compounds content and improved red color, while in February it increased flesh firmness.
