GROWTH OF LUJA PLANTS (PERISTRHOPHE BIVALVIS MERRILL) AT DIFFERENT LIGHT INTENSITIES AND MATERIAL TYPES OF CUTTINGS

Abstract

Light intensities and planting materials of cuttings are two critical factors affecting plant growth. This research was aimed to find out the effects of light intensities and planting material types of cuttings affecting the growth of Luja plants. The light intensity treatments consisted of 100%, 65%, 35%, 15% and the planting material types covered both basal and tip cuttings. The design used was Split Plot Design and continued with Duncan's Test. The results showed that there was no interaction between light intensities and cuttings, but the effect of light intensities and cuttings was singularly found in the SLA, RGR, LAD, LAR, and NAR variables. Moreover, Luja plants could grow well at the light intensity of 15% - 65% with the optimum light intensity of 35%. Both basal and tip cuttings could be used as the planting materials. However, the material type of cuttings that could accelerate the vegetative phase-growth of Luja plants the most was tip cuttings. Luja is categorized as a plant that can grow in full light conditions.
