Responses of heading-back and thinning-out pruning on white pitaya (Hylocereus undatus) were studied in the commercial orchard.
Shoots thinned-out in November or December resulted in earlier vegetative- bud sprouting and higher percentage of their transformation into flowering shoots from either current or non-current year shoots, although their initial flowering dates did not differ from the unthinned ones.
Current shoots were headed-back in June to 30, 60, 90, or 120 cm of length.
Those retained 120 cm of length had the earliest initial flowering and the highest percentage of transforming into flowering shoots.
Shoots were headed-back 10%, 25%, 50%, and 75% of their original length in February.
During the initial flowering period, the percentage of current or non-current shoots retained as vegetative increased whereas their transformation into flowering shoots decreased with increasing severity of pruning.
Current shoots with 10% of heading-back length had the earliest and the highest percentage of flower-bud formation.
Current shoots were headed-back 10% of their original length during January, February, March, and April and those pruned in January, February, and March showed earlier initial flowering and higher percentage of transforming into flowering shoots.
The results indicated that different types of pruning can be used for manipulating vegetative and reproductive growth of white pitaya.
韓國首爾舉辦第27屆國際園藝學年會
也是皮塔屋第一次參加國際型的會議
第一次踏上國際舞台 第一次感受到學術研究的魅力
研究過程中的孤獨與等待
就是在這一刻得以嶄露頭角
這條學術研究的漫漫長路 或許也蠻有意思的
