Growth and flowering performance evaluation of thirty two chrysanthemum cultivars

Abstract

An experiment was conducted to evaluate the growth and flowering performance of chrysanthemum cultivars. Thirty two chrysanthemum cultivars coded from V1 to V32 were used in the experiment. Plant height, number of branch per plant, leaf area, number of leaf per branch, chlorophyll content, days to flower bud initiation, days to first petal spread, days to final bloom, number of flower bud per plant, number of flower per branch, number of flower per plant, bud diameter at initiation stage, bud diameter at mature stage, flower head diameter, stalk length and flower durability in plant (days to 50% flower senescence) for different cultivars varied significantly. Number of flowers per plant ranged from 4.3 to 194.6, flower head diameters varied from 2.8 to 17.6 cm and stalk lengths were from 4.4 to 20.1 cm. Amongst the chrysanthemum cultivars V15 (BARI chrysanthenum1) was the maximum flower producing cultivar, while V1 produced the largest flowers and flowers from the V21 had the longest shelf-life. These variations might help in classifying chrysanthemum, for pot cultivation and cut flower, based on their flowering quality which will be beneficial for growers.

Evaluation of chrysanthemum (Dendranthema grandiflora Tzvelev) genotypes for morphological and yield traits during different seasons

“…The number of flowers produced per plant may be directly related to increase in plant height, more number of branches per plant, greater plant spread and increased number of leaves per plant and accumulation of more photosynthates, thereby leading to the production of more number of flowers. The similar results also were observed by Parul et al (2011) [30] ; Dhanumjaya and Sushma (2014) [7] ; Uddin et al (2015) [9] ; Chezhian et al, 1985; Suvija et al (2016) [45] in chrysanthemum and in gerbera (Mahmood et al, 2013) [21] .…”

“…Higher yield might be due to increase in morphological parameters like plant height, number of leaves and leaf area, plant spread and number of branches which might have contributed in production of more photosynthates resulting in production of more number of flowers per plant which might have contributed in production of more photosynthates resulting in greater accumulation of dry matter which in turn leads to production of more flower yield. Similar results are obtained in chrysanthemum by Jamaluddin et al (2015) [9] ; Palai et al (2018) [28] ; Sharma, (2014) [39] ; Ramzan et al (2014) [37] ; Kumar et al (2016) [15] Munikrishnappa et al (2013) [23] in China aster. Similar findings reported by Patil (2001) [31] in carnation and (Naik et al, 2005) in marigold.…”

Variability of Chrysanthemum Species under Prayagraj Agro-climatic Conditions

“…Nursery raising of chrysanthemum/Guldaudi: Nursery sowing is done by suckers or terminal cuttings (5-7 cm long). Nursery raised by suckers is planted in February-March while nursery by terminal cuttings (5-7 cm long) is planted in June-July [9,10].…”

Influence of growth promoters on fourteen gerbera (Gerbera jamesonii) cultivars

“…Published with open access at journalbinet.com EISSN: 2312-7945, ©2021 The Authors, Research paper(Mantur et al, 2005;Fascella and Zizzo, 2005), in chrysanthemum(Uddin et al, 2015b). Stalk length of gerbera varied among the cultivars and maximum 56.77 cm were found bySankar et al (2003).…”
