STUDY 1: Evaluating Hard Pinch Timing of Dendranthema X Morifolium On Lateral Shoot Branching And Flowering Response

Institution

Murray State University

Abstract

Standard cultural practices on hardy chrysanthemums, Dendranthema x, becomes a labor issue when planting and pinching operations are done at ground level on 2,800 plants on separate dates. The study compared hard pinching at planting and then at the recommended 7-10 day interval. The research had four different cultivars of chrysanthemums. They were Foxy Marjorie, Marjorie, Bethany and Okra. Each row of 120 plants had three control/treatment groups which consisted of 40 plants each. These plants were grown on a regular production schedule. Just before being sold, the plants were measured for area index (width x width x height). Morifolium is to make a hard pinch 7-10 days after planting the rooted cutting. These Photographs were taken straight down on the plant's canopy where flower buds were counted. After data collection is finished, a summary will direct future hard pinching practices for the horticulture program's yearly chrysanthemum production.
