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.

Abiotic stresses influences survival, biomass production and crop yield in negative manner. Proline is an electro cyclic low molecular weight protein amino acid of glutamate family has attracted considerable attraction of many ecophysiologists in last two decades. It is an organic osmoprotectant accumulates in a large number of plant species exposed to environmental stresses such as salinity, drought, extreme temperature, UV radiations and heavy metals (Hare and Cress 1997- Zhu et al. ,
1998- Rhodes et al., 1999- Taylor 1996- Yamada et al., 2005- Eraslan et al., 2007). Proline is involved in the regulation of osmotic homeostasis, scavenging of reactive oxygen species and protection of cell structures (Srinivas and Balasubramanian 1995- lyer and Caplan 1998). Proline is a
