Abstract

Detached tobacco (Nicotiana rustiest L.) leaves were exposed for 2 min to a temperature range of 24° to 47.5°C. The heat treatment enbanced O₂ uptake by 30 Vs. Likewise, amylolytic activity in chloroplast extracts was intensified; this activity being observed also in situ. The enhancements can be reversed either by short‐term cold treatment (7°C for 10 min), or by application of kinetin.
