Abstract:
Zamioculcas zamiifolia mainly propagated by division–simply separating or cutting the plant roots into two clumps and replanting them. The best part of growing plants in water is that pest and disease issues are reduced and if changed frequently, will not spread disease abundantly. Unfortunately, availability of scientific literatures has filled a lacuna on water as well as other soilless rooting media too. Looking to the importance of as pot plant, the study was carried out on Zamioculcas zamiifolia to determine the impact of different concentration of IBA, rooting media and its interaction on rooting and survival. Twelve treatment combinations comprising four levels of IBA concentration i.e. I₁: Control, I₂: 250 ppm, I₃: 500 ppm and I₄: 750 ppm with three different rooting media i.e., M₁: Water, M₂: Cocopeat + vermicompost (3:1 v/v) and M₃: Sand + vermicompost (3:1 v/v) were used in experiment. When compared to all treatments, leaflet cutting treated with 750 ppm IBA and placed in water media (I₄M₁) produced maximum number of roots, longest root length, root diameter, rooting, fresh and dry weight of root and number of sprouts on callus and survival at 75 days after placing of cutting for rooting. Whereas, callus diameter, fresh and dry weight of callus were recorded higher in I₄M₃-750 ppm IBA with sand + vermicompost @ 3:1 v/v. At 90 days after transplanting in black polythene bags, maximum number of leaves per plant and total number of leaflets per plant were noted in I₄M₁. According to the aforementioned results, propagation of Zamioculcas zamiifolia through one pair of leaflets cutting along with rachis dipped in IBA @ 500 ppm for 30 minutes and placed in water media produced better callus, roots and biomass for getting higher survival and establishment.
