“…The results of our study were strongly supported by Renu (2019), who reported that 200 ppm of GA 3 maintained the highest value of RWC in V. radiata leaves. Several studies showed that exogenous application of GA 3 remarkably increased the RWC in many crops such as faba bean (Al-Whaibi et al, 2010), chickpea (Hossain et al, 2015), wheat (Aldesuquy and Ibrahim, 2001;Hammad and Ali, 2014), maize (Kaya et al, 2006), sweet potato (El-Tohamy et al, 2015), cut flowers (Emongor, 2004), and Thymus vulgaris (Pazoki et al, 2012). Application of GA 3 improved the root growth in our study ( Tables 5, 6) which might help to uptake more water in plants.…”

This study evaluated the role of gibberellic acid [GA3; (0, 100, 200, and 300 ppm)] in modulation of the growth, physiology, yield, and quality traits in two varieties (BARI Mung-6 and BARI Mung-8) of mungbean (Vigna radiata L.). Irrespective of the two varieties (BARI Mung-6 and BARI Mung-8), 100, 200, and 300 ppm of GA3 differentially modulated the tested parameters (relative water content, RWC; photosynthetic pigments: chlorophyll a, chlorophyll b, and carotenoids; growth parameters: fresh and dry weights of leaves, petioles, stems, and roots; yield contributing traits such as plant height, number of pods plant−1, number of grains pod−1, pod length, and 100-grain weight; quality traits such as grain nitrogen and protein). However, compared to the lowest GA3 (100 ppm) and the highest GA3 (300 ppm), the moderate concentration of GA3 (200 ppm) led to highest values of leaf-RWC, where this parameter exhibited 16.1 and 13.4% increase in BARI Mung-8 and BARI Mung-6, respectively. Similarly, the tested herein growth parameters and the yield traits significantly increased up to the foliar application of the moderate GA3 concentration (200 ppm), and thereafter these traits decreased with 300 ppm GA3. The 200 ppm-led changes in the growth and yield traits were significantly higher in BARI Mung-8 when compared to BARI Mung-6. Considering the quality traits, GA3 positively influenced the nitrogen and protein content in grains, where 200 ppm of GA3 led to increases of 25.2% in N, and 17.7% in protein over control in BARI Mung-6; whereas, BARI Mung-8 exhibited 28.3% in N, and 18.3% in protein with 200 ppm GA3 over control. Overall, BARI Mung-8 significantly responded to the foliar supply of 200 ppm GA3 when compared to BARI Mung-6. Hence, in order to high yield and grain protein content, the application of 200 ppm GA3 may be applied in V. radiata before and during flowering. The major mechanisms underlying the responses of the water relation, growth, and yield traits to the GA3 concentrations need to be explored.

“…The stem biochemical status is directly involved in stem bending (Ferrante and Serra 2009). Significantly higher water content and reduced stem bending and flower senescence resulted from applied exogenous GA (Emongor 2004). Stem bending may be due to lower water potential and changes in physiological and biochemical components in the cut flower (Prashanth et al 2010).…”

“…Based on vase life and other criteria it can be graded for three gerbera cultivars as follows: orange > magenta > yellow. Cultivar differences for vase life have been reported in gerbera (Ferrante et al, 2007;Nazari deljou et al, 2011;Emongor, 2004) and roses (Ichimura et al, 2002). Increase of flower vase life was found by the application of different floral preservatives in gerbera (Pavana et al, 2015a) rose (Pavana et al, 2015b), orchid (Pavana et al, 2015c), tuberose (Jamal Uddin et al, 2015), gladiolus (Mehraj et al, 2013a) and chrysanthemum (Mehraj et al, 2013b).…”

An experiment was conducted to evaluate the postharvest life of cut gerbera cultivars under the different preservative solutions. Three (yellow, magenta and orange) cut gerbera cultivars were placed on nine different preservative solution viz. ) following completely randomized design. Yellow gerbera provided the maximum petals water content (52.4%) when placed in T9 and also provided 8.0 days more vase life compared to the control. For magenta and orange gerbera, maximum petals water content (magenta: 56.3% and orange: 63.0%) in T8 and also 6.9 days more vase life than control.
