IMPACT OF FLY-ASH, LIGHT AND SHADE ENVIRONMENTS ON GROWTH AND CHEMICAL RESPONSE OF ALBIZIA-PROCERA AND ACACIA-NILOTICA

Results of the present investigation indicate that lower concentration of flyash favoured the growth of Albizia procera and Acacia nilotica. However, higher concentrations had adverse effects. On the basis of s torage substances, ascorbic acid, proline, phenol and amino acids in b oth the species, it can be concluded that Acacia nilotica can very wel l survive in shade as well as light. Albizia procera, however, exhibit ed higher values for storage substances only in light-exposed plants; there was a stress on plants in shade areas.
