Morphological and Physiological Responses of Clinacanthus Nutans Under Different Light Conditions

Abiotic stress such as light can cause injuries or damage to the plant cells biochemical processes in plants. Difference of conditions resulted different morphological and physiological responses This study is done determine response Clinacanthus nutans under condition results defense mechanism. one species that contains higher medicinal value currently being commercialised alternative treatment treat various ailments. Four weeks was on five samples each condition. Observation morphologically shows A (exposed fully sunlight) appear bigger stem diameter, longer root length, height pale colour compared B (shaded polyethylene netting). However, for leaf size parameter, has leaves A. Meanwhile, analysis, there difference chlorophyll content based (0.83 ± 0.463 Ca, 1.46 0.740 Cb 0.03 0.015 carotenoids A, 0.50 0.321 1.47 0.539 0.105 B) contain photosynthetic rate a result dry matter (0.27 0.017) It suggested ensure more accurate, period should be analysis primary secondary metabolites conducted.
