title: Diurnal variation of asparaginase in developing pea leaves.
abstract: Levels of asparaginase activity from developing pea leaves (Pisum sativum) were found to change on a daily basis, increasing during the light period and decreasing in the dark. During extended periods of light, high levels of activity were maintained, while prolonged dark reduced activity to a low value. Half-expanded leaves exhibited the greatest change in activity over the photoperiod. Very young or mature leaves displayed little or no diurnal variation in asparaginase activity.
