‘国色天香’李适宜授粉品种的筛选

Selection of Suitable Pollinizer Varieties for‘Guose Tianxiang’Plum

新品种‘国色天香’李果肉硬脆、香味浓郁、外观艳丽、丰产性好且较耐晚霜,适合暖温带和部分亚热带地区栽培。但其自花结实率低,栽植时需配置授粉树。为了给商业化栽植中授粉树的选择提供理论依据,作者选取‘国馨’‘国峰17号’‘国美’‘国丽’‘龙园蜜李’‘大红袍’‘美丽李’7个李品种作为授粉品种,调查其花期、花粉活力,以及对‘国色天香’李授粉的坐果率。结果表明,‘国馨’‘国峰17号’‘国丽’3个品种花期与‘国色天香’李一致,且花粉萌芽率高,对主栽品种授粉坐果率高,适合作为授粉品种。

The new variety of‘Guose Tianxiang’plum exhibits hard and crispy flesh,high yield,bright appearance,good fertility,and is more resistant to late frost.It is suitable for cultivation in warm temperate zone and some subtropics regions,but its self flowering and fruiting rate is low.Pollination trees need to be equipped when planting.In order to provide theoretical basis for the selection of pollinating trees in commercial planting,selecting to seven plum varieties as pollination varieties,including‘Guoxin’‘Guofeng 17’‘Guomei’‘Guoli’‘Longyuan Honey Plum’‘Dahongpao’and‘Meili Plum’,investigate the flowering period,pollen vitality,and pollination and fruiting rate of‘Guose Tianxiang’plum separately.The results showed that the three varieties of‘Guoxin’‘Guofeng 17’and‘Guoli’have overlapping flowering periods with‘Guose Tianxiang’plum,high pollen germination rate,and high fruit setting rate when pollinating with the main variety,making them suitable as pollinating varieties.
