Correlation studies between chilling sensitivity of stored basil leaves and their composition of membrane lipids.

 

Results of experiments on detached fresh leaves of basil (Ocimum basilicum) showed that the phase transition temperature of a chilling sensitive cultivar increased from 12.5 to 17 deg C during 1-6 days of storage, whereas that of a less sensitive cultivar was much lower and remained between 3 and 5 deg throughout storage. The leaves of the chilling sensitive cultivar showed a reduction in the oleic acid composition of membrane phosphatidylglycerol and a reduction in the palmitic acid composition of membrane phosphatidylcholine compared with leaves of the less susceptible cultivar.
