THE INFLUENCE OF THE EXTRACT OF SOME CROPS AND SOIL RESIDUES ON GERMINATION AND GROWTH

摘要: Six plant species were germinated in sand wetted with water extracts of tissues five field crops and three soils. Deionized was used as a check f he study conducted using standard seed germination techniques.Alter 7 to 10 days all the seeds harvested measurements made shoot root lengths.Alfalfa extract caused greatest reduction length well m percentage germination. It increase time required for Timothy not quite harmful alfalfa. Extracts oats, corn potatoes still less potato causing least effect.The soil generally had very little effect when compared deionized water.Plant showed marked differences tolerance alfalfa being most resistant timothy least.Where alone rate per cent high or higher than other extracts, but ro...
