Effects of Ethylene on Hermaphroditic Cucumbers
Cucurbit Genetics Cooperative Report 4:8-10 (article 4) 1981 Amy Iezzoni and C. E. Peterson University of Wisconsin, Madison, WI 53706 Ethrel, an ethylene releasing compound, has been demonstrated to alter the growth and flowering habit of monoecious cucumbers. Several of the most striking alterations include a decrease in internode length and a reduction of staminate […]
