GROWTH REGULATORS, DATES OF TREATMENTS, YIELD AND QUALITY OF BROAD BEAN (VICIA FABA L.) AND FLORENCE FENNEL (FOENICULUM VULGARE MILL. VAR. AZORICUM THELL.) "SEED".
It can be concluded that treatments had no beneficial effects on 'seed' germination of fennel.
Faba bean plants, at 6-leaf stage, at flowering of the first node and 11 days later were treated 1,2 or 3 time with PCB, CCC, GA3 and 2,4-dichlorophenoxy acetic acid (2,4-D) at 2 rate of application.
GA3 treatments increased the number of aborted seed; the yield per plant decrease by increasing the rate and the number of treatments.
Double and triple CCC treatments lowered 1000 seed weight but they improved germination value 6 months after harvest. Later treatments with PCB increased the germination value; 2,4-D elevated seed size and 1000 seed weight. In general, growth regulators had a little influence on germination percentage.
