Abstract

Soluble and insoluble invertase occurs in dormant pollen of Haemanthus albiflos, with pH optima of 5·7 and 5·5 respectively. At their pH optima the activity of the soluble enzyme is 3·5-fold higher. After 2 hr germination the pH optimum of the insoluble invertase is increased to 6·0 and the activity is increased 2-fold while the activity of the soluble invertase is decreased by 26%.
