    Question: Internal fruit necrosis in aonla (Indian gooseberry) is due to –

    Options:

    (a) Zinc deficiency (1)
    (b) Iron deficiency (2)
    (c) Manganese deficiency (3)
    (d) Boron deficiency (4)

    ✅Explanation:
    Internal fruit necrosis in aonla is a physiological disorder primarily caused by boron deficiency. Boron is an essential micronutrient required for cell wall formation, pollen germination, and fruit development. When aonla trees lack sufficient boron, the fruit's inner flesh can turn brown or black, leading to internal necrosis. This can significantly reduce fruit quality and yield.

    📌Other Options Explanations:
    (a) Zinc deficiency: Zinc deficiency can cause other problems in aonla, like leaf chlorosis and stunted growth.
    (b) Iron deficiency: Iron deficiency also causes chlorosis.
    (c) Manganese deficiency: Manganese deficiency can lead to interveinal chlorosis.
