Floral malformation is a main constraint to reduce fruit yield in mango plants. Recently, we report on the role of putrescine in normalizing the functional morphology of mango flower by reducing various adverse effects of ethylene. Here, ethrel, an ethylene releasing compound, was exogenously applied to mango plant cv Amrapali to evaluate the response of flower development under high level of ethylene. Scanning electron microscopy (SEM) study showed that ethrel treated flowers were observed to progressively be deformed and remain unbloom. The flower buds were not distinguishable and flower parts such as petals, sepals, anther and stigma were not properly developed. The stamen showed fused anther lobes and carpel depicted curved style with pointed stigma. The findings of present study suggest the involvement of ethylene to abort the functional morphology of flower and thereby development of malformation.
