Properties of peach flower buds which facilitate supercooling.
Water in dormant peach (Prunus persica [L.] Batsch. var. ;Harbrite') flower buds deep supercooled. Both supercooling and the freezing of water within the bud axis and primordium as distinct components depended on the viability of the bud axis tissue. The viability of the primordium was not critical. Supercooling was prevented by wounding buds with a dissecting needle, indicating that bud struct...
متن کاملSupercooling in overwintering azalea flower buds.
Differential thermal analysis and nuclear magnetic resonance spectroscopy experiments on whole flower buds and excised floral primordia of azalea (Rhododendron kosterianum, Schneid.) proved that supercooling is the mode of freezing resistance (avoidance) of azalea flower primordia. Increase in the linewidth of nuclear magnetic resonance spectra for water upon thawing supports the view that inju...
متن کاملSupercooling characteristics of isolated peach flower bud primordia.
The amount of unfrozen water in dormant peach (Prunus persica [L.] Batsch, cv Redhaven) flower buds, isolated primordia, and bud axes was determined during freezing using pulse nuclear magnetic resonance methods. Differential thermal analysis studies were conducted on whole buds and isolated primordia in the presence of ice nucleation. The results showed that some of the water in isolated primo...

متن کاملLive confocal imaging of Arabidopsis flower buds.
Recent advances in confocal microscopy, coupled with the development of numerous fluorescent reporters, provide us with a powerful tool to study the development of plants. Live confocal imaging has been used extensively to further our understanding of the mechanisms underlying the formation of roots, shoots and leaves. However, it has not been widely applied to flowers, partly because of specif...
