초록

Beneficial effects of glucosinolate in Chinese cabbage on human health have propelled researches on biochemical and genetic characteristics of glucosinolate and Chinese cabbage. However, growth conditions which are practically important in producing functional Chinese cabbage and in optimizing glucosinolate have been little focused. The objective of this study, hence, was to identify growth conditions affecting glucosinolate contents so that the result could be used for further optimizing glucosinolate in Chinese cabbage. We used principal component analysis (PCA) for analyzing glucosinolate contents in Chinese cabbage cultivated under various growth conditions in the plant factory. As a result, PCA showed that two principal components were able to explain more than 76% of variations in glucosinolate contents caused by different growth conditions. The first principal component (PC1) was mainly represented by humidity and temperature, while growth duration was the main component of PC2. From these results, it was conclusive that glucosinolate contents in Chinese cabbage were largely affected by humidity, temperature and growth duration.
