Effects of Leaf Extracts of Eucalyptus and Other Plant Species on the Rooting of Cuttings and Seed Germination of Several Plant Species

The results of this investigation indicated that the leaf extract of Eucalyptus urophylla S.T.Blake inhibited the rooting rate,root number and the length of roots of mung bean cuttings by 85.71%,58.96% and 93.52%,respectively;inhibited the rooting rate of pea cuttings by 100%;inhibited the germination rate of India mustard (Brassica juncea var. napiformis) and wild cabbage (Brassica oleracea var. caulorapa) seeds by 69.58% and 60.72%,respectively.The leaf extracts of airplant kalanchoe (Kalanchoe pinnata) inhibited the root length of mung bean cuttings by 38.12%;inhibited the rooting rate,root number,and root length of pea cuttings by 14.23%,23.53% and 26.90%,respectively;and inhibited the germination rates of India mustard and wild cabbage seeds by 41.97% and 53.60%,respectively.The leaf extracts of Setcreasea purpurea promoted the rooting rate,root number,and root length of pea cuttings by 119.06%,11.76% and 22.05%,respectively.
