FIGURE 6.

Effect of DMTU on fruit abscission in detached longan clusters. (A) Image of H₂O₂ distribution in the pedicel sampled from water-fed clusters (control) 1 day after detachment. (B) Image of H₂O₂ distribution in the pedicel sampled from dimethylthiourea (DMTU) solution-fed clusters 1 day after detachment. (C) Cumulative fruit abscission with days after detachment. Vertical bars indicate standard errors. Asterisks indicate that the paired means were significantly different at P = 0.05, t-test (n = 5).
