GA3及Fulmet對黑后葡萄花穗發育之影響

Effect of GA3 and Fulmet on Inflorescence Development in Black Queen Grapevines

摘要


以不同濃度GA3或添加Fulmet於新梢4葉期處理黑后葡萄花穗,發現GA3處理可促進花穗伸長達15~41%,在相同濃度處理以第一收之效果較好,其適當濃度為10~25 ppm,而添加Fulmet可促進花蕾及子房增大達20~50%,其濃度為5~10 ppm之間。

The inflorescence development of Black Queen (Vitis vinifera L.×Vitis labruscana Bailey) grapevine was investigated after inflorescence treated with various concentration GA3 and Fulmet at the 4th leafing stage. The results showed that the inflorescence elongation could be enhanced by GA3 treatment. Fulmet promoted the size of the floret and ovary. Under the same concentration treatment of GA3, the inflorescence length, fresh weight of floret and ovary of the second harvest were lower than that of the first harvest. Based on the result, the suggested optimum concentration for GA3 treatment was 10~25 ppm, combined with Fulmet at 5~10 ppm.
