Acid lime fruits are a matter of research because of its importance to agriculture and human diet. It is highly valued for its medicinal value. Acid lime (Citrus aurantifolia Swingle.) is one of the most important commercial citrus cultivars al and nutritive value irrespective of its economic significance in its daily use as well as in pickle industry. Acid lime fruit growth follows smooth sigmoidal type during fruit development. The patterns of fruit growth and changes in biochemical quality parameters were assessed at 15 days interval from fruit set to maturity. The fruits attained maturity in 120 days after fruit set when skin colour changed from green to yellowish green. There was a continuous increase in fruit size throughout the growth phase. At maturity, fruit weight reaches a peak of 97.85g and fruit juice recovery was 57.91%. The peel thickness and peel % decreased with progressive increase till it reaches full maturity; while pulp% and pulp to peel ratio showed an ascending trend with maturity. The value of specific gravity at peak maturity was 0.98. Based on the characteristics of different indexes, TSS and TSS/TA ratio revealed advancing trend with advancing maturity and reached the steady status during 105-120 days after fruit set.
