Abstract

SummaryIn Kenya, at Kabete (1941 m), GA3 applications at 100 and 250 mg 1−1 promoted flowering in cabbage cvs Sugar Loaf and Giant Drumhead but cv Golden Acre did not flower. The same levels of GA3 promoted flowering in kale cv Collards, but failed in cv Thousand Headed. There was a small percentage of natural flowering in all cabbage and kale cvs that flowered. At Molo (2554 m), Sugar Loaf flowered with and without GA3 application, but plants treated with GA3 flowered earlier. Cvs Giant Drumhead and Golden Acre did not flower with or without GA3, but some plants of both cvs bolted without flowering. Kale cvs Thousand Headed and Curled Scotch flowered poorly with and without GA3.
