An experiment was conducted to study the effect of benzyl adenine and gibberellic acid on flowering and flower quality attributes of gladiolus (Gladiolus hybridus L.) cv. summer sunshine in Department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere (Under University of Agricultural and Horticultural Sciences, Shivamogga) during 2017-18. The experiment was consisted with sixteen different treatments viz., BA (100, 200 and 300 ppm), GA3 (150, 200 and 250 ppm) and their combinations along with the control. Each treatment was replicated thrice in Randomized Complete Block Design (RCBD). | Effect of Benzyl adenine and Gibberellic acid on flowering and flower quality attributes of Gladiolus 2018 7 8 944-950 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 08 2018 Journal homepage http Original Research Article https Effect of Benzyl Adenine and Gibberellic Acid on Flowering and Flower Quality Attributes of Gladiolus Priyanka S.

The experiment was consisted with sixteen different Gladiolus BA GA3 treatments viz. BA 100 200 and 300 ppm GA3 150 200 and 250 ppm and their and flowering combinations along with the control. Each treatment was replicated thrice in Randomized parameters Complete Block Design RCBD . The results revealed that GA3 at 150 ppm recorded Article Info minimum days taken for spike initiation first floret opening days 50 per cent flowering days maximum spike girth mm spike weight g Accepted floret length cm and floret diameter cm . However GA 3 at 250 ppm 08 July 2018 recorded maximum duration of flowering days spike length cm rachis Available Online 10 August 2018 length cm florets per spike and vase life days . Whereas BA at 300 ppm exhibited the maximum number of days for spike initiation first floret opening
