Abstract

Abstract:

To investigate the effects of detasseling time and the number of top leaves removed on ear traits of the fresh edible sweet-waxy maize cultivar Wenkenuo 1, four detasseling treatments were set up: T1, detasseling on May 23rd, 3.30 top leaves removed; T2, detasseling on May 26th, 2.10 top leaves removed; T3, detasseling on the day of tasseling (May 29), 0.80 top leaves removed; T4, detasseling on June 2nd, 0 top leaves removed. A non-detasseled treatment served as the control. Ear traits were investigated and analyzed at harvest. The results showed that ear length, bald tip length, kernel number per row, fresh ear weight, and net ear weight in all detasseling treatments were greater than those in the control, while ear diameter was smaller. This may be related to the indeterminate growth characteristics of the ear axis in Wenkenuo 1. Among the treatments, T3 exhibited the highest fresh ear weight and net ear weight, indicating that detasseling at the tasseling stage with 0.80 top leaves removed achieved the best yield-enhancement effect for Wenkenuo 1.

Key words: maize, fresh edible sweet-waxy maize, Wenkenuo 1, detasseling, top leaf, ear trait
