Abstract
The present investigation entitled understanding the changes in anthocyanin degradation, ion leakage and malondialdehyde in the ageing petals, during stem bending of cut gerbera (Gerbera jamesonii Bolus) cvs Stanza and Rosalin were carried in the laboratory, Department of Floriculture and Landscaping, Bidhan Chandra Krishi Viswavidyalaya during the year 2021-2022. The results of the present study revealed that anthocyanin content in the petals was recorded highest at no bending stage in both the cultivars and declined further till full bending stage. The highest anthocyanin (3.56 mg/g FW) was noted in cv Stanza at no bending stage. Whereas the ion leakage and malondialdehyde content gradually increased in both the cultivars as the senescence progressed to full bending stage from no bending stage. The highest ion leakage (78.32%) was noted in cv Rosalin at full bending stage and the highest malondialdehyde (323.51 nmol.ml-1) was noted in cv Stanza at the full bending stage.
