INFLUENCE OF WATER STRESS ON FREE PROLINE CONTENT IN THREE DIFFERENT LINUM USITATISSIMUM VARIETIES
*S. A. Gaikwad, D. K. Gaikwad & P. D. Chavan
ABSTRACT Proline is cyclic amino acid is synthesized from glutamate. It is well known that free proline accumulates in plants in response to various types of environmental stress, such as drought, salinity, high temperature, nutrient deficiency and exposure to heavy metals and high acidity. In present investigation here is an attempt to know effect of PEG induced water stress on proline accumulation in different varieties of Linum usitatissimum (Local variety from Sangola, NL97 and Nagarkot variety). It can be concluded from result that proline content in all flax varieties shows positive response to water stress condition. NL 97 variety found superior than other studied varieties. This variety may be useful for farmers for cultivation at any climatic condition. It can be said that these flax varieties self tried to resist water stress by highly accumulating of proline and controlling osmotic adjustments under such adverse environmental conditions. Keywords: Water stress, Linum usitatissimum, Proline, Local Flax variety, NL97 variety, Nagarkot variety. [Download Article] [Download Certifiate] |
