The effects of root cooling on leaf growth


, : The effects of root cooling on leaf growth. Monograph British Society for Plant Growth Regulation ( 21): 149-161

When roots of 6- or 7-d-old seedlings of Phaseolus vulgaris Canadian Wonder, grown hydroponically at 23 degrees C, were cooled to 10 degrees , expansion of the primary leaves fell to very low rates within 2 min and leaf ABA concentration rose within 15-30 min. Bulk leaf water potential (LWP) fell within 10 min and gradually recovered over 3-4 h.

Malone, M., 1993: Rapid inhibition of leaf growth by root cooling in wheat: kinetics and mechanism. Cooling of the roots was shown here to cause marked and rapid inhibition of leaf growth in wheat seedlings, as in some other species. The root-shoot signal involved in this response was investigated. Displacement transducers were used for the simu...

The ratio of the components changed during ontogenesis of the...

Root cooling of 7-day-old wheat seedlings decreased root hydraulic conductivity causing a gradual loss of relative water content during 45 min (RWC). Subsequently (in 60 min), RWC became partially restored due to a decrease in transpiration linked...
