Influence of Some Ecological Factors on Growth, Productivity, and Chemical Constituents of Spurge (Euphorbia Condylocarpa M., Bieb)

Abstract

Spurge Euphorbia condylocarpa is one of the medicinal plants, which contain numerous sorts of phytochemical components. This study aimed to determine the effect of three levels of light intensity (100% (L1: received natural sunlight, 80% (L2: the glass house covered with one layer of tulle fabric to minimize the light intensity to 80%), 120%(L3 where electric light was added was added to make light intensity to 120%), soil moisture content (SM 1: 100%,SM 2:75%, SM 3: 50% field capacity (FC)), under applied two levels of organic fertilizer (OF1; control, OF2;10%) on growth, productivity, and chemical constituents of E. condylocarpa plants. Results showed that L3 significantly increased root tuber fresh weight, total chlorophylls, total protein content, and total phosphorus content, however, proline decreased, while L2 significantly decreased number of leaves, root tuber fresh weight, root tuber dry weight, and chl. a content of leaves but proline content of leaves increased. SM1 significantly increased number of leaves, chl. b content, carotene, and total soluble carbohydrates, SM2 significantly increased total phosphorus, but decreased ch. b content, and total soluble carbohydrates. OF2 significantly increased stem diameter, total chlorophylls, proline content of leaves, and total potassium, while OF1 significantly decreased stem diameter, and total potassium content, while zinc increase in dry leaves. Triple interaction treatment L3SM2OF2 significantly increased number of branches, stem diameter, water content of shoot system, biological yields, shoot fresh weight, total chlorophylls, and total soluble carbohydrates in dry weight of leaves. It was concluded that this plant needs different condition for improve growth and development.
