Influence of Nitrogen, Deblossoming, and Growth Regulator Treatments on Growth, Flowering, and Runner Production of the ‘Gem’ Everbearing Strawberry1

Year: 1978

Type: article

Abstract: Uniform everbearing strawberry plants ( Fragaria × ananassa Duch. cv. ‘Gem’) were treated with 60 and 100ppm N, 50 and 100ppm gibberellic acid (GA 3 ), and 50 and 100ppm (2-chloroethyl) phosphonic acid (ethephon) in the greenhouse. One half of the plants were deblossomed as flowers emerged. Both GA 3 and N increased runner production and vegetative growth, independently and without interaction. Ethephon and deblossoming were generally ineffective on the measured characters except that 100ppm ethephon reduced leaf fresh weight and deblossoming increased inflorescence number. Highly significant interactions were observed among ethephon and higher levels of GA 3 and N. ‘Gem’ flowering and runner production appear independent of each other with deblossoming of no practical value in promoting runner production.
