Effect of auxin treatments on male and female cuttings of Hippophae salicifolia

Abstract

Hippophae salicifolia (Seabuckthorn) is one of the potential multipurpose underutilised plant species having huge multipurpose benefits including economic and ecological. Effect of different concentrated doses of auxins, on rooting percentage, number of root per rooted cuttings and root length of male and female stem cuttings was examined under open field condition. Results show that the cuttings pretreated with 50 mg L^-1 indole-3-butyric acid (IBA) had best rooting traits (respectively for male and female rooting percentage was 50.00 and 76.67%, root number was 2.3 and 3.0 and root length per rooted cuttings was 2.5 and 3.5 cm). Therefore, cuttings pre-treated with 50 mg L^-1 IBA is recommended for vegetative propagation through cuttings in H. salicifolia. Moreover, this study provides a significant lead towards the development of a simple cost-effective propagation technique for large scale cultivation and future domestication of the elite genotype for better nutritional security along with socio-economic upliftment and sustainable rural development in Indian Himalayan Region.

Key words: Seabuckthorn, vegetative propagation, dioecious plant.
