Present investigations indicate a high level of various phosphorus fractions in deblossomed shoots as compared to fruited shoots during the period of flower bud formation as well as during the period of fruit growth. While the low level of phosphorus in fruit carrying shoots appears to limit the production of new flush of growth after harvesting and subsequent initiation of flower buds, its high amount in deblossomed shoots throughout, along with the other desirable factors, seems to be favourable for the formation of flower buds.
