Growth, physiological and flowering responses of Xanthostemon chrysanthus (F. Muell.) Benth. to paclobutrazol and potassium nitrate / Ahmad Nazaruddin Mohd Roseli

Xanthostemon chrysanthus (F. Muell.) Benth. or golden penda (locally known as jambu kuning) is gaining its popularity in Malaysian landscape. However, under local climatic condition, the flowering of X. chrysanthus is very erratic and inconsistent. An investigation on the growth, physiology, floweri...

Significant higher coarse sand content in soil of PBM influenced the water holding capacity, causing significantly lower growth responses, especially the relative growth rate of canopy diameter and leaf area index.
