Influence of different light intensity on early growth of Jatropha curcas L. seedlings

This study investigated the influence of different light intensities on the early growth of Jatropha  curcas seedlings. Forty (40) seedlings were randomly selected from the germinated seedlings in the nursery and arrayed under four different treatments (0, 20, 40 and 60% light intensity).

Pre-sowing treatments for enhancing germination of Guibortia coleosperma and Amblygonocarpus andongensis seeds from Kazuma Forest Reserve, Botswana

The effect of seed presowing treatment on Guibortia coleosperma and Amblygonocarpus andongensis was investigated. Seeds of both species were subjected to four experiments, containing 10 levels of presowing treatments: mechanical scarification, soaking in concentrated sulphuric acid (for 15, 30, 45 and 60 min), immersion in boiling water (for 1, 3 and 5 min), and soaking in boiling water (and cooling down for 24 h) and...
