Effects of Several Growth Regulators on Runner Plant Production, Yield and Fruit Maturity of the Strawberry

Growth and Flowering of Day-neutral and Everbearing Strawberry as Affected by Ethephon1

“…Blatt and Sponagle (2) increased runner plant yields on 'Redcoat' in the greenhouse with ethe phon when applied during the flower bud initiation period. The lack of runner response may strictly be an effect of the 4 cultivars examined, because strawberry cultivars vary in their response to ethephon (3). In our study, some runners of ethephon-treated plants emerged stunted, but this effect was not quantified.…”

“…Plants dug on Dec. 3,1980, were stored at 4°C for 6 weeks. The plants were planted in 15-cm plastic pots in a medium of 1 sand: Treatments of 0, 500, and 1000 ppm ethe phon (Amchem Products, Inc., Ambler Pa.) were sprayed to runoff on plants with open primary flowers; control plants were sprayed with water.…”

The Physiology of Flowering in Strawberry

“…Ethylene application during floral induction increased fruit number and yield in SD strawberry (Blatt and Sponagle 1974). Similarly, Cain et al (1983) reported that ethylene increased fruit number and yield in field grown DN cultivars.…”
