Plants accumulate proline under a variety of stress conditions thereby preventing stress-caused damages. The proline accumulation in germinating seeds of pigeonpea in response to NaCl, Boron and Aluminium treatments were studied. Results showed increased accumulation of proline in salinity stressed germinating seeds. As compare to 100 ppm boron, 10 and 50 ppm of boron treatments promoted proline levels at different stages of seed germination. The content of proline was found to be induced by all aluminium concentrations particularly at 48, 72 and 120 hrs. of seed germination. Whereas reverse pattern of proline accumulation was observed at 96 hrs stage under all studied stresses.

Key words: Aluminium, Boron, Pigeonpea, Proline, Seed germination, NaCl
