'캠벨얼리' 포도의 화수(花穗) 생장과 과실품질에 미치는 GA3의 영향 Effects of GA3 Dipping Treatment on the Spike Growth and Fruit Quality at Harvest of 'Campbell Early' Grapevine원문보기
수확 시 과방의 생장(과방중, 과방장, 과방폭, 과병의 직경크기, 과병장)은 무처리에 비하여 GA3 10 mg·L-1 처리가 증가되었다. GA3 농도별 과립의 생장 (과립수, 과립중, 과립경, 과립장)은 차이가 없었으나 지경중은 무처리에 비하여 GA3 5, 10, 20, mg·L-1 처리 농도에서 증가되었다. 그러나 GA3 40 mg·L-1 처리는 차이가 없었다. 과립의 밀착정도, 과분 발생 정도, 가용성고형물 및 과피의 착색 정도는 큰 차이가 없었으나 무핵 정도는 GA3 10 mg·L-1 처리에서 다른 처리에 비하여 증가하였다. 과립의 열과 발생률은 무처리에 비하여 GA3 농도 5, 10, 20, 40 mg·L-1에서 현저하게 감소하였다. 과립의 탄저병 발생률은 큰 차이가 없었다. 과방당 총 지경장은 무처리, 20 및 40 mg·L-1 처리에 비하여 5 및 10 mg·L-1처리에서 현저하게 증가하였다. 지경 순서에 의한 1번 지경부터 15번 지경까지 지경장은 GA3 10 mg·L-1 처리는 증가하였다.

This study has been conducted to investigate the effect of GA3 solution dipping treatment after 1 days full bloom on spike growth and fruit quality at harvest of 'Campbell Early' grapevine. The fruit cluster growth(weight, length, width) and fruit stalk(diameter, length) at harvest were increased significantly by GA3 10 mg·L-1 solution dipping treatment compared to control and another concentration. The berry growth (berry No, weight, length, diameter) at harvest showed no difference by treatment GA3 concentration different. Spike weight was increased by GA3 5, 10, 20, mg·L-1 treatment compared to control, but no difference GA3 40 mg·L-1 treatment. The degree of compact berry, bloom, skin color and SSC at harvest by GA3 solution dipping treatment were not significantly different from those of control. but increased seedlessness induction by GA3 10 mg·L-1 treatment. The occurrence percent of berry cracking by GA3 5, 10, 20, 40 mg·L-1 treatment significantly decreased. The bitter rot of berry harvest showed no difference by treatment GA3 concentration different. Total spike length was increased by GA3 5, 10 mg·L-1 treatment compared to control and GA3 20, 40 mg·L-1 treatment. The spike length of 1st from 15th to position increased by GA3 10 mg·L-1 treatment.
