Physiological characteristics of floral organ distribution and abscission for adzuki bean(Vigna angularis)under different short day-length photoperiod treatments
摘要
Abstract
In order to identify the effect of different short day-length treatment on and the flower organ formation and abscission,and the corresponding floral organ abscission site response characteristics of the important physiological index the experiment was carried out at the Experiment Station of Agro-meteorology in Agricultural University of Hebei in 2015.Adzuki bean Tangshan adzuki bean,a medium and late maturing variety,was treated with three photoperiods: shading from growth cone mast section period to inflorescence bracts and branch differentiation; shading at floret differentiation stage;shading from pistil and pistil differentiation to flower organ completion,using the natural light treatment as the control.Starting from the appearance of the initial flowers,we carried out the short-day photoperiod treatment to determine the development progress,the formation and abscission of the flower,and the important physiological indexes.The results showed that: shading at floret differentiation stage could decrease the proportion of flower organ prolapse,on average 6.6％lower than that of the other two short day treatments,which was advantageous to the part section of flowering.Shading at the floret differentiation stage could reduce the content of ionoic acid and gibberellin,with an average ratio of 8.53％and 8.92％in the whole growth period.Shading at the floret differentiation stage could also reduce the activity of ionofibrinase and polygalactosaccharide,declining by 25.15％and 21.88％on average.Shading at the floret differentiation stage treatment could significantly improve the content of pectic substance and lignin in 10d after flowering.关键词
