The lowest survival of 40-45 % (average number of roots=4.2, average length of roots=8.0 cm, average number of leaves=32.2, average number of sprouts=1.7) was observed for the control stem cuttings.
The influence of IBA treatment at 7000 ppm concentration showed survival of 85.22% (average number of roots=10.4, average length of roots=15.5 cm, average number of leaves=92.4 and average number of sprouts=3.3) while IAA showed survival of 81.11% (average number of roots=9.1, average length of roots=14.6 cm, average number of leaves=84.0 and average number of sprout=3.0) at the same concentration. A total of 3840 stem cuttings were treated with IBA and IAA and grown in polythene bags containing soil at Lalku valley, Swat, Khyber Pakhtunkhwa (KP), Pakistan. the propagation of Himalayan yew by the regeneration of fresh stem cuttings using hormone treatments of Indole Butyric acid (IBA) and Indole acetic acid (IAA) at 2000 to 7000 ppm concentrations. However, Himalayan yew is an endangered tree species and requires high conservation attention due to declining population. The tree contains anticancer drug 'Taxol' which is mainly used for the treatment of ovarian, breast, and AIDS-related cancers. Himalayan yew (Taxus wallichiana) is one of the most important medicinal plant species for cancer treatment. For the latest updates please visit our dedicated page. Hence our study suggests and recommends the application of IBA (7000 ppm) as a better hormone for the conservation and propagation of Himalayan yew. IMPORTANT ANNOUNCEMENT: CORONAVIRUSThe health, safety and wellbeing of our community is a priority. The present study enhanced the potential of conservation and propagation of T. Lowest survival 40–45% (average number of roots = 4.2, average length of roots = 8.0 cm, average number of leaves = 32.2, average number of sprouts = 1.7) was noticed for controlled cuttings. The influence of IBA treatment (7000 ppm) showed a survival of 85.22% (average number of roots = 10.4, average length of roots = 15.5 cm, average number of leaves = 92.4 and average number of sprouts = 3.3) while that of IAA treatment (7000 ppm) the survival of 81.11% (average number of roots = 9.1, average length of roots = 14.6 cm, average number of leaves = 84.0 and average number of sprout = 3.0) were more significant followed by 2000–6000 ppm (IBA and IAA). In the same way, 3840 cuttings were treated with IBA and IAA from November 2016 to November 2017 at Lalku valley, Swat, Khyber Pakhtunkhwa (KP), Pakistan. Butyric acid (IBA) and Indole acetic acid (IAA) hormones treatments (2000–7000 ppm) through stem cuttings (140 each). The study being reported here was conducted for the propagation of Himalayan yew by using two different trials of Indole. This metabolite is mainly used for the treatment of ovarian, breast, AIDS-related cancers, and other indications. Himalayan yew (Taxus wallichiana) is one of the endangered medicinal plants species having great importance due to the presence of anticancer drug Taxol.
