Fig. 32. Fruiting feature of Campbell-Early clusters treated with gibberellin (1960).

A : Sprayed on May 12 (13 days before full bloom), and sprayed once again

on the 20 th day after full bloom.

B : Unsprayed control.

berries (1960).

T : Sprayed on May 12 (13 days before full bloom), and sprayed once again

on the 10th day (la), or the 20 th day (lb) after full bloom, 2 : sprayed

twice, and 4: the four times as postbloom treatment.

N. T.: Sprayed on May 12, without any postbloom treatment.

Fig. 36 and 37. Fruiting feature of Campbell-Early clusters treated with gibberellin

(1963).

Fig. 36. All the plots were treated on May 13 (11 days before full bloom), and

then treated none (A), once (B), twice (C), or four times (D), respec-

tively postbloom treatment.

E : Control, treated with Airrol-op at 100 ppm.

Fig. 37. F : Treated on May 13, and treated once again as postbloom treatment.

G : Treated twice on both May 13 and May 18, and treated once again

as postbloom treatment.

H : Control, treated with Airrol-op at 100 ppm.

I : Untreated control.
