Standardization of Macro-Propagation Protocol of Toona ciliata M. Roem under Punjab Conditions

Toona species are amongst the most valuable timbers of tropics and the backbone of forest based industries in many countries throughout the world. The study was conducted during 2018 to standardize the macropropagation protocol of Toona ciliata under Punjab conditions. Two types of cuttings (stem and coppiced) were grown under two different growing media viz., vermiculite and Soil: Sand: FYM (1:1:1) treated with 4 treatments (500, 1000, 1500 and 2000 ppm each of IBA and NAA including control and were evaluated for 6 characters under two different planting conditions viz., mist chamber and greenhouse. The experiment was conducted in three different growing seasons viz., mid-March, mid-July and mid-November. Season mid-March provide better performance followed by season mid-July whereas season mid-November was poorest. Vermiculite media gave better results than Soil: Sand: FYM media, IBA than NAA, mist chamber conditions than greenhouse conditions and stem cuttings gave better results than coppiced cuttings. Stem cuttings planted in mid-March season, treated with IBA500 ppm, planted in vermiculite media and grown under mist chamber conditions came out to be the best combination to get significant and fruitful results.
