Flowering time is an important trait in chrysanthemum, but its genetic basis remains poorly understood. An intra-specific mapping population bred from the cross between the autumn-flowering cultivar 'Yuhualuoying' and the summer-flowering 'Aoyunhanxiao' was used to determine the number and relative effect of QTL segregating for five measures of flowering time. From flowering time data recorded ...

Ethylene is a gaseous phytohormone that delays flowering in Chrysanthemum morifolium Ramat. To date, however, there have been no systematic studies on genes involved the ethylene response of this species, and mechanism underlying ethylene-delayed remains unclear. Herein, we applied RNA sequencing to characterize by comparing transcriptomes chrysanthemum cultivar ‘Jinba’ with or without ethephon...

Heat shock proteins (HSPs) play important roles in various stress conditions. In this study, CmHSP90.5, whose expression is induced by heat and salt, was cloned from a chrysanthemum (Chrysanthemum morifolium) ‘Jinba’ expressed Arabidopsis. We found that CmHSP90.5 localized the chloroplast. The heterologous of weakened tolerance Arabidopsis reduced activity antioxidant enzymes, including superox...

The insidious flower bug, Orius insidiosus (Say) (Hemiptera: Anthocoridae), is a generalist predator that feeds on western thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), larvae and adults. Our study involved series of experiments conducted under laboratory greenhouse conditions from 2017 to 2020 to: 1) determine the number bug adults should be released manage thrips po...

This study was conducted in the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology and Sciences, Prayagraj (UP) from October 2021- March 2022 to investigate Effect Fertigation Intervals on Plant Growth Flower Yield Multiflora Chrysanthemum (Chrysanthemum morifolium) cv. Branfountain Purple. The experiment laid...

The stem xylem conduit dimensions and hydraulic conductivity of chrysanthemum plants (Dendranthema x grandiflorum Tzvelev cv. Cassa) were analysed and quantified. Simple exponential relations describe conduit length distribution, height dependency of conduit length distribution, and height dependency of stem hydraulic conductivity. These mathematical descriptions can be used to model the xylem ...
