[0063]

[0064] Table 2

[0065] The results in Table 2 show that: 50 grams of 10% propyl dihydrojasmonate (PDJ) soluble powder per acre can increase sugar content, but it has little effect on fruit color change, being roughly equivalent to the control. 100 grams per acre increases both sugar content and promotes earlier color change. 200 grams per acre significantly increases sugar content and promotes earlier color change, with the number of grape bunches turning color more than double that of the control, and sugar content increasing by more than 2 percentage points. 400 grams per acre is comparable to 200 grams per acre, but weaker vines showed yellowing leaves, so its use is not recommended. In conclusion, 200 grams of 10% PDJ per acre is the most effective for drip irrigation, with no risk of yellowing leaves in weaker vines.

Using 200 grams per acre was even more effective in promoting earlier ripening and increasing fruit size compared to 100 grams per acre. The effects of using 300 grams per acre were comparable to those of using 200 grams per acre. In conclusion, drip irrigation using 200 grams of 10% PDJ per acre showed the most significant effect.
