抄録

The efficacy of ammonium nitrate (AMN), NH4NO3, as an additive to gibberellic acid (GA3) solutions on berry growth and quality of seedless 'Delaware' grape was tested in 1995 (Expt. 1) and 1996 (Expt. 2). Clusters were dipped twice in GA3 ± AMN solutions before and after full bloom in both years. Treatments with GA3 alone are considered the control. The addition of AMN to 50 and 100 ppm GA3 induced significantly larger growth rates than those of GA3 alone during the early growth stage. At 12 days after full bloom (DAFB) cell sizes of berries that received the combined treatments were significantly larger than those that were treated with 50 ppm GA3. At harvest, there were no significant differences in seedlessness and titratable acidity between treatments with or without AMN. However, in Expt. 1, the total soluble solids content (TSS) in berries from the combined treatments tended to be slightly lower than that in berries treated with GA3 alone; in Expt. 2, no difference was observed, except with the treatment of 100 ppm GA3 + 25 mM AMN. AMN, when combined with 50 ppm GA3, produced more larger berries than did the 100 ppm GA3 treatment. These results indicate that treatment with 50 ppm GA3 + 25 mM AMN has the potential to produce larger berries with slightly lower TSS than do treatments without AMN or with 100 ppm GA3 alone.
