“…These results are also in agreement with the reports of Sainath et.al. (2014) in annual chrysanthemum, Kumar et al (2015) in China aster and Syiemlieh et al (2016) in petunia. Dalal et al (2009) stated that the increment in flower diameter with GA 3 application might be due to enhanced cell division and cell enlargement, promotion of protein synthesis coupled with higher dry matter accumulation.…”

Effects of plant growth regulators on quality flower and seed production of marigold (Tagetes erecta L.)

et al. 2020

Effects of different growth regulators and their application time on production of quality flower and seed production of marigold (Tagetes erecta L.) were investigated. Experimental factors include nine foliar applications of growth regulators viz., Control (no application), two doses each of GA3, salicylic acid, benzyl adenine, cycocel, and two application times viz., (i) application at 25 DAT, (ii) application at 50 DAT. Results suggest that foliar spray of 250 ppm gibberellic acid enhanced growth, and improved seed yield and quality parameters of marigold. Among the times of application tested, it was observed that application at 25 days after transplanting (DAT) gave superior values for all the flower and seed parameters under study.

“…Results also showed that number of primary branches per plant increased due to 50 ppm GA 3 treatment whereas, number of secondary branches per plant responded negatively following all treatments. Previously Kumar et al (2015) reported increased number of primary and secondary branches per plant following GA 3 treatments in China aster. Application of Rhizobium inoculation and 50 ppm GA 3 treatments had stimulating effect in shoot length although, length of root was found to decrease due to all treatments except 50 ppm GA 3 .…”

“…Investigations all over the world showed that GA 3 at appropriate concentrations had beneficial effect on different parameters of economically important plants viz., green gram (Akbari et al 2008), mungbean (Abdel and Al-Rawi 2011), chickpea (Thakare et al 2011 andMazid 2014), tomato (Kumar et al 2014), cowpea (Nabi et al 2014), china aster (Kumar et al 2015). On the other hand, plant growth promoting bacteria (PGPB) play pivotal role in plant growth by producing phytohormones, fixing N 2 asymbiotically, solubilizing inorganic phosphate, mineralizing organic phosphate and supplying nutrients (Dey et al 2004).…”

Growth, yield and biochemical responses of BARI chhola-9 (Cicer arietinum L.) to GA3 and rhizobium application

A field experiment was conducted to investigate the responses of various concentrations of GA3 (10, 20, 50 ppm) and Rhizobium inoculation on growth, yield and biochemical parameters of BARI Chhola-9. Foliar application of 50 ppm GA3 resulted maximum plant height, number of primary branches per plant, shoot and root length, fresh and dry weight of shoot and root and biomass duration per plant with significant variations in case of fresh and dry weight of shoot and biomass duration. The stimulatory effect of 50 ppm GA3 on number of pods per plant, fresh and dry weight of pods per plant, number of seeds per pod, number of seeds and straw yield per plant and weight of 1000-seed eventually produced 4.76% higher yield over the control. Yield parameters of BARI Chhola-9 showed almost negative response to Rhizobium and 10 ppm treatments with a few exceptions. Pigment content of leaves also increased due to 50 ppm GA3 treatment at both vegetative and flowering stages where, significantly higher amount of chlorophyll a and b were recorded from flowering stage although statistically similar to 20 ppm GA3 treatment. However, protein content of leaves increased following Rhizobium and 10 ppm GA3 treatments at vegetative stage and to all treatments at flowering stage but, increase in protein content of seeds was recorded from Rhizobium treatment only. Out of four treatments, 50 ppm produced better yield.

“…Controlling plant size is one of the most important aspects in floricultural crops which can be achieved genetically, environmentally, culturally or chemically (Gopichand et al 2014;Kumar et al 2015). However, effective strategy for controlling plant height is to use plant growth retardants.…”

An experiment was conducted to study the effect of graded concentrations of foliar applied growth retardants (cycocel and B-nine) on the growth and flowering of Chrysanthemum morifolium cv. Flirt. Uniform rooted cuttings raised in pot soil culture received spray applications of growth retardants viz., cycocel and B-nine prepared in 0.1% Tween 80. Cycocel was applied at 1000, 2500 and 5000 mgL -1 , whereas B-nine was applied at 100, 250 and 500 mgL -1 concentrations. Plants were sprayed at 2 and 6 weeks after transplantation. Visual observations, plant height, fresh mass, dry mass, number of laterals, number of inflorescences and inflorescence diameter were recorded at periodic intervals. Cycocel treated plants recorded a significant increase in fresh and dry mass of whole plants, leaves and roots, whereas B-nine treated plants were comparable with the controls. Cycocel and B-nine treated plants showed early emergence of buds and inflorescences, whereas no significant effect was recorded on number of laterals. Cycocel application resulted in the increase in inflorescence number. The present results suggest that the treatment effect may be cultivar dependant as many other cultivars of chrysanthemums have been chemically tailored with desired effects using cycocel and B-nine.
