Summary
The effect of extracellular products fromAulosira fertilissima on the growth of rice seedlings (IR-8) has been studied. There is indication of liberation of a root-promoting hormone from the alga. The growth pattern of rice seedlings, treated with algal filtrate, parallels that of seedlings treated with gibberellic acid. An increased growth of rice seedlings results when they are treated with algal filtrate obtained from the exponential phase of the alga. The amino acid-treated seedlings do not show any marked increase in growth. Filtrate fromAnacystis nidulans, on the other hand, do not show any growth promoting response. The possibility of liberation of kinins byA. fertilissima does not appear to be involved.
