Abstract

Dipcadi erythraeum is an important medicinal bulbous plant of the Indian arid zone under endemic and threatened category. So, it is necessary to cultivate it at large scale for its conservation. As plant growth regulators are known to improve germination percentage, the present research has been conducted to investigate the effect of different concentrations of plant growth regulators such as gibberellic acid, indole-3-acetic acid and indole butyric acid on various parameters of seed germination and seedling growth of D. erythraeum. The different parameters such as viability, reproductive capacity, seed output, germination percentage, vigour index and germination value were taken. The results revealed that seeds pre-treated with growth regulators improved germination and other parameters as compared to control.
