Abstract/ Executive Summary:

Phosphorus deficiency caused a decrease in the accumulation of reducing sugar in the leaves and stems but increased in the roots of lentil (Lens culinaris Medik.). Accumulation of insoluble protein was depressed in lentil following P-deficiency. Phosphorus deficiency increased proline and phenolic compounds in roots and stems and anthocyanin in leaves compared to control.

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

To study the effects of phosphorus deficiency on the accumulation or distribution of reducing sugar, insoluble protein, proline, phenolic compounds and anthocyanin in lentil.

Methodology:

Seeds of lentil (Lens culinaris Medik. var. Barimasur-4) 2n=14, were collected from Bangladesh Agricultural Research Institute, Joydebpur, Gazipur. Plants were grown in with or without phosphorus culture solution for biochemical study. Seedlings were subjected to phosphorus deficiency for 7, 14, 21 and 28 days in triplicates. Reducing sugar was determined by Somogyi-Nelson method (Nelson 1944, Somogyi 1952). Insoluble protein estimation was done according to Lowry et al. (1951), while proline was estimated following the method of Bates et al. (1973), total phenolic compounds according to Malik and Singh (1980) and anthocyanin according to Sims (2003).

Achievement/Findings:

The increase in the amount of reducing sugar in the roots with concomitant decrease in the stems and leaves might be due to increased translocation of reducing sugars from the leaves to roots. Phosphorus deficiency inhibited the accumulation of insoluble proteins in the roots and the stems of lentil. Accumulation of reducing sugar declined in leaves and that of insoluble protein also declined in the root and stem of lentil at 14 days of treatment in both control and phosphorus deficiency. The decline of reducing sugar and insoluble protein may be due to increase in growth having rate of accumulation of these compounds constant. Phosphorus deficiency resulted in an increase in total phenolic-compounds in intact lentil and more phenolic compounds were distributed to the root.
