Container Size During Propagation and Transplant Date Influence Growth of Two Ilex Species
Patricia R. Knight, D. Joseph Eakes, Kenneth M. Tilt and Charles H. Gilliam
Stem cuttings of Ilex cornuta ‘Dwarf Burford’ and Ilex ‘Nellie R. Stevens’ were direct stuck into four different container sizes and transplanted 10 and 20 weeks later into trade-gallon containers. Shoot growth and root distribution were influenced by container size and time of transplanting. Plants propagated in small container sizes (cell packs and rose pots) when transplanted at 10 weeks had similar root growth outside a quart-container volume compared to plants propagated in large size containers (quarts and trade gallons). Plants propagated in cell packs and rose pots and transplanted into trade gallons 20 weeks after sticking had lower shoot numbers and dry weights compared to plants propagated in quart containers and transplanted at either 10 or 20 weeks. Plants propagated in quart pots were similar in size regardless of transplant date and were the largest plants in the study.
