Effect Of Different Environments And GA3 On Growth And Runners Production Of Strawberry (Frageria Ananasa)
Strawberry (Frageria ananasa) is the fruit of temperate climate but some cultivars are adaptable to sub-tropical climate as well. In Pakistan, strawberry runners are only produced in Swat Mingora, Khyber Pakhtunkhwa. This research was aimed to produce runners in Punjab environments. Therefore this research was carried out at Pir Mehar Ali Shah Arid Agriculture University.Rawalpindi, during the years 2017-18. Strawberry cultivar “Chandler” were treated with different concentrations (control, 150 ppm, 300 ppm and 450 ppm) of gibberellic acid in four different environments (open field, plastic tunnel, glass house and lath house) to investigate their effect on vegetative growth and runners production. Data was recorded for plant height, crown diameter, petiole length, count of leaves, count of trusses, count of runners, leaf area, weight of fresh leaves, weight of dry leaves and canopy size. Results unveiled that strawberries cultivated in a lath with 450 ppm GA3 application gave exceptional results for all the observed parameters except crown diameter and canopy spread, which were superior in open field crop and treated with 450 ppm GA3 solution. Hence it can be concluded that strawberries cultivated in a lath house with 450 ppm GA3 application produces excellent quality plants and capable to produce runners for the next season.
