ABSTRACT

Linseed (Linum usitatissimum L.) is an oil seed crop and is taken as a marginal as well as intercrop between chickpea and safflower in many parts of Solapur district which is normally a drought prone area. Generally, it is well known fact that enzyme lipases plays a key role during seed germination. Hence here in the present investigation, an attempt has been made to study effect of Chickpea leaf leachates, Safflower leaf leachates, NaCl treatments and Plant Growth Regulators treatment and PEG treatments on lipase enzyme activity in different Linum usitatissimum varieties during germination. It was noticed that the activity of lipase was found to be reduced due to PEG induced water stress, in all the three varieties while salt stress was found to cause marked inhibition of enzyme lipase in Local and Nagarkot varieties, chickpea and safflower leaf leachates adversely affect the lipase activity at 5% concentration while lipase enzyme activity was found to be enhanced due to all PGR treatments.
