ABSTRACT
The field experiment aimed to evaluate the growth response of three Lilly cultivars (Sorbonne, Montezuma, and Crystal Blanco) under four cultivation conditions: open field, shade lath house, green shade netting, and polyethylene tunnels. The study was conducted at the Cut Flower Production and Technology Dissemination Islamabad, Pakistan) using a randomized complete block design (RCBD) with factorial arrangements. All plant growth parameters were measured at maturity. Results demonstrated that variety Crystal Blanco exhibited the greatest plant height (86.9 cm) under green shade netting. This cultivar also produced the thickest stems (8.4 mm) under both shade lath house and green netting conditions. Additionally, Crystal Blanco displayed the largest leaf area (153.9 cm²) when grown in polyethylene tunnels. The maximum number of leaves per plant (38) was observed for Crystal Blanco cultivated in a greenhouse environment. Notably, the number of flower buds per plant did not exhibit significant variation across growing conditions, although Crystal Blanco again displayed a trend of superior performance. The largest bud diameter (20.2 mm) was recorded for Crystal Blanco grown under green netting. Crystal Blanco cultivated in a shade lath house demonstrated the longest vase life (8 days). In conclusion, this investigation suggests that the Crystal Blanco cultivar exhibited superior growth performance compared to the other two cultivars under both green shade netting and polyethylene tunnel in Pothwar region of Pakistan. Further research is warranted to elucidate the underlying physiological mechanisms responsible for the enhanced performance of Crystal Blanco under these specific growing conditions.
