Abstract
Jurinea dolomiaea is an important medicinal and aromatic plant species of Kashmir Himalaya. Due to its tremendous overexploitation the species has been listed as endangered for Himalayan region. In this study we carried out the propagation of J. dolomiaea using rhizome cuttings. Propagation through rhizome cuttings is a means towards conserving the species and making available planting material of this species for cultivation. Bringing more species under large-scale cultivation helps reduce the pressure on the wild stocks. We investigated the sprouting ability and percentage survival of rhizome cuttings under ex situ conditions including soil textures, moisture contents and different concentrations of Indole acetic acid (IAA), Indole butyric acid (IBA) and Gibberellic acid (GA3) treatments. A better rooting response (p ≤ 0.05) was observed with GA3 25 ppm treatment when compared to zero hormone soaked. Key words: Rhizome cuttings, field capacity, Indole acetic acid (IAA), Indole butyric acid (IBA) and Gibberellic acid (GA3), vegetative propagation.
Highlights
Jurinea dolomiaea Boiss., commonly known in Kashmir as dhup, of family Asteraceae was selected for present study
After 48 h of treatment control and segments treated with the plant growth regulators (PGRs) were planted in earthen pots containing sandy loam soil in Kashmir University Botanical Garden (KUBG)
Sprouting percentage of rhizome cuttings of J. dolomiaea varied in different soil textures and moisture content of soil (Table 1)
Summary
Jurinea dolomiaea Boiss., commonly known in Kashmir as dhup, of family Asteraceae was selected for present study. It is endemic to Himalaya and is distributed from. Pakistan to East Nepal between 3000 and 4300 m in open slopes (Chauhan, 1999). It is an important medicinal and aromatic herb of North Western Himalaya and is being exploited because of its medicinal values. A decoction of the roots is cordial. It is given in the treatment of colic and puerperal fever. The juice of the roots is used in the treatment of fevers, diarrhoea and stomachache. The crushed root is applied as a poultice to eruptions (Chopra et al, 1956).
