Abstract: A field research on efficacy of different bioregulators on flushing, flowering and fruiting of acid lime was conducted at Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal. Acid lime being tropical fruit crop, its flushing and fruiting is dependent on the variation of climatic factors. In order to have a thorough understanding on the issue a critical review of the research findings was made and the results of the experiment were validated in the light of the review. The discrete concept for induction of flowering indicated that flushing and flowering in acid lime is regulated through stress (soil moisture and low temperature), through application of growth regulators. Imposition of stress measured in terms of soil moisture and low temperature resulted uniformity in flushing, as uncontrolled flushing is undesired. Flowering is related to the season rather than physiological maturity of the shoot. Out of the different bioregulators viz., bromouracil, 2, 4-D and paclobutrazol in variable doses in different agro-climatic condition are effective for induction and regulation of the crop..
