Artificial pollination timing of Actinidia eriantha 'Bidan' for commercial production
Actinidia eriantha is not popularly known as green or gold kiwifruit in Korea. Previous studies have shown that Bidan fruit becomes excellent health functional food. Bidan fruit is also easy to eat because its fruit skin is easily peeled out when ripen. This study was conducted to promote the industrialization of Bidan by finding an efficient way of pollination to produce the high quality fruits of. In 2018 to 2019, three practices of artificial pollination were compared in a commercial farm in Haenam Korea. One was 2 times pollination at 30 and 80% full bloom (2TP). Another was single pollination at 50% full bloom (1TP50) and the other was 80% full bloom (1TP80), respectively. 2TP took 1.7 times longer pollination time than 1TP50. The commercial grade fruit production rate (over 15 g fruit‑1) at 2TP, 1TP80 and 1TP50 were 93, 61 and 61% respectively. The labor cost and time for thinning was 15% lower at 1TP80 than 2TP and 1TP50. Either 1TP50 or 1TP80 do not seem enough to secure proper yield although thinning time and cost increase. Considering the yield of quality fruit and labor cost of fruit thinning, 2TP would be recommendable for the commercial production of Bidan fruit.
