Effect of growth regulators on lipase activity of peanut during germination

Lipase activity is affected by the growth regulator treatments prior to germination of the seeds. The order of magnitude of this effect is as follows: Suc > MH ⋍ AA > Sul > DW ⋍ GA > control. The effect induced by the growth regulators is explained on the basis of interfering effect of the regulators with the functions of mitochondria. The lipase activity of all the seeds is found to increase with the period of germination reaching maximum values on different periods. The increase of lipase activity is not only dependent on the plant physiology, but other metabolic products such as ascorbic acid oxidase and amino acids produced during germination also play a great role on its production in oil‐bearing seeds.
