Flower quality parameters and vase life studies of standard chrysanthemum cultivars (Dendrathema grandifloraTzvelev) in polyhouse conditions

Abstract

SUMMARY :An experiment was conducted to evaluate the flowering and vase life performance of standard chrysanthemum cultivars in naturally ventilated polyhouse condition. Among five standard chrysanthemum cultivars Snow ball recorded maximum plant height (115.79 cm), early flower bud initiation (83.50 days), flower stalk length (96.72 cm), flower diameter (14.08 cm) whereas cv. CHANDRAMA recorded maximum flower stalk girth (11.20 mm) and weight of cut stem (156.99g). The maximum vase life (14.00 days) was observed by cv. GOLDEN YELLOW in vase life solution of sucrose (2 %) + 8HQC (500 ppm). The maximum fresh weight ( 76.53 g) was recorded by cv. CHANDRAMA on second day. Snow Ball recorded maximum (11.76 g) transpiration loss of water on day 1-2 whereas the maximum (9.48 g) water uptake was noted by cv. SNOW BALL on day 0-1 followed by Angel Pink (6.82 g).How to cite this article : Siddiqua, Asma, Lakshmi, K. Swarajya, Nagaraju, R., Reddy, D. Srinivasa and Shaheda, S. (2017).

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

“…Aishwarya-1 (55.67 days) recorded maximum duration of flowering which was on par with cv. Scent White (55.33 days) ( [41,17,45] . Similar results for variation in flowering duration among the genotypes have also been reported in chrysanthemum under different environmental conditions by Swaroop et al (2008) [46] , Singh et al (2008) [42] and Rao and Pratap (2006) [38] .…”

“…Among the chrysanthemum genotypes from the pooled mean, cv. [41] . 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.…”

“…The difference in yield may be due to the additive gene effect (Behera et al, (2002) [5] . Lakshmi et al (2008) [41] suggested that this character may be due to genetic behaviour of the genotype. By combining all the seasons, cv.…”

Assessment of variability, genetic diversity and character association of Chrysanthemum (Dendranthema grandiflora Tzvelve) based on qualitative and quantitative traits

“…Flowers are symbol of beauty, love and tranquillity, they form the soul of the garden and convey the message of nature. Besides their aesthetic and religious value, owers are also important for their economic use (Siddiqua et al, 2018). One such ower, out valuing all utilities of the world through its magni cent beauty, varying hues and colors is the golden ower 'chrysanthemum'.…”
