Low-oxygen storage of whole and minimally-processed Pak choi.

Pak choi [Brassica chinensis] cv. Shanghai whole shoots or pulled-off leaves were placed in air-flow chambers at 10 deg C under a range of oxygen atmospheres (0-21% O2). Senescence was characterized by leaf yellowing. Leaf age had a direct effect on the degree of yellowing, with oldest leaves yellowing significantly more than younger leaves. Older unattached leaves generally yellowed faster than corresponding leaves of intact plants. Pulling off leaves resulted in similar respiratory rates to those of intact shoots; cutting leaves off at the petiole resulted in respiration rates about 80% higher than this. Low oxygen atmospheres (0.5-1.5% O2) significantly retarded leaf yellowing of both attached and unattached leaves compared with higher ones.
