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...
