Efficacy of GA₃on growth and flowering regulation ofin vitroraised hybrid gerbera under shade net

Effect of Plant Growth Regulators on Growth, Yield and Flower Quality of Gerbera (Gerbera jamesonii L.) cv. Pink Elegance under Naturally Ventilated Polyhouse (NVPH)

“…Significantly maximum plant height, number of leaves and plant spread may be due to gibberellic acid which has resulted in cell division and cell elongation resulting in enhanced vegetative growth. Similar observation in maximum plant height were also obtained by Dalal et al, (2009) and maximum plant spread at 150ppm were also obtained by Patra et al, (2015) in gerbera (Fig. 1).…”

Effect of Foliar Application of Gibberellic Acid (GA3) Concentrations and Spraying Frequencies on Vegetative and Floral Attributes of China aster [Callistephus chinensis (L.) Nees.]

“…Increase in flower number due to GA 3 treatment may be attributed to the fact that GA 3 enhances induction of flower bud break i.e., differentiation of floral primordial in the apical growing region by GA 3 which leads to the increased production of flower per plant (Singh and Srivastava, 2008). The above results are in conformity with the findings of Kumar et al, (2003) in China aster and Patra et al, (2015) in gerbera. Enhancement of flowering duration under GA 3 treatment could be due to early flower induction as a result of replacement of a part of vernalisation by GA 3 .…”

Effect of Different Plant Growth Regulators and their Levels on Floral Yield and Vase Life of China Aster [Callistephus chinensis (L.) Nees] cv. Shashank

“…Apart from this CCC also showed the best results in terms of minimum duration for bud initiation T 11 (51.67 days), minimum days to flowering T 11 (65.86 days) and with maximum vase life T 11 (9.00 days). The reason for enhancement of flower size and diameter of flower might be due to increase in length of petals and pedicles and it was caused by drawing photosynthates to the flower as a consequence of intensification of sink it was reported by Sainath et al, (2014) in china aster, Patra et al, (2015) in gerbera and Palei et al, (2016) in African marigold.…”
