Studies on Flowering and Fruit Setting of Introduced Vaccinium spp. Cultivars in Yunnan Province

The survey and observation were conducted in Kunming area on the growth feature, the flowering and fruiting characteristics of some introduced Ericaceae vaccinium cultivars by means of comparative trial and random sampling methodology. The results showed that all the 6 cultivars observed were of good ornamental value, which would be appropriate for greening purpose, whereas ‘Dingfeng’ cultivar would be good for fruit production. Trees of ‘Yuamlan’ and ‘Diana’ cultivars grew well, but their fruit setting rate was comparatively low, whose flowering duration was 60d and 40d respectively. ‘Dingfeng’ cultivar was recommended as fruit production because the trees grew well with large fruits and high fruit setting rate, and the dynamic growth and development of the fruit length was approximately similar to that of the breadth diameter.
