The Effect of Moringa Leaf Lxtract (MLE) on Sprouting and Growth Responses of Stem Cuttings of China rose (hibiscus rosa- sinensis l.)

Özet

The China rose, also known as Hibiscus rosa-sinensis , is a tropical flowering plant renowned for its large, vibrant blossoms. It is native to East Asia and thrives in warm climates. The propagation of China rose ( Hibiscus rosa-sinensis ) face several challenges, such as Rooting difficulty, inconsistent growth so that the present study investigates the effects of Moringa Leaf Extract (MLE) on the sprouting and growth responses of stem cuttings of Hibiscus rosa-sinensis L. ( China Rose ). Healthy, mature, and disease-free moringa leaves were carefully collected from near the Faculty of Crop Production Sindh Agriculture University, Tandojam. The leaves were washed under running water and then kept in a freezer for a day. Subsequently, the frozen leaves were crushed to extract juice with a locally made mortar and pestle. Moringa leaf extract was made with different concentrations, after which it was passed through a sieve before applying it to the cutting. The cuttings were 9 inches long and soaked for 5 hours in four different concentrations of MLE (10%, 20%, 30%, and 40%) they were planted in plastic bags filled with canal silt. the research utilized a Completely Randomized Design and assessed various growth parameters including sprouting percentage (%), number of sprouts per cutting, rooting percentage (%) fresh root biomass (g), dry biomass of roots (mg), fresh shoot biomass (g), Dry biomass of shoot (mg), Root Collar Diameter (mm). Results revealed that while sprouting percentages reached 100% at all MLE concentrations, the number of sprouts per cutting peaked at 10% MLE, indicating enhanced growth responses at this concentration. Furthermore, MLE significantly improved rooting percentages and biomass metrics, with optimal results observed at 10% concentration, while higher concentrations led to diminished effectiveness. The study concludes that MLE serves as a potent growth promoter for the propagation of China Rose, highlighting its potential in horticultural practices.
