Growth,Head Formation and Leaf Surface Characteristics of Bloomless Cabbage Cultivar

Abstract

The growth,head formation and leaf surface characteristics of bloomless cabbage cultivar ‘Yuryoku’ were investigated in comparison with a normally bloomed cabbage cultivar ‘Kinsyu’. Leaf surace of ‘Yuryoku’ seen through a scanning electron microscope was smooth. Compared with ‘Kinsyu’, the colors of outer leaf and head surface of ‘Yuryoku’ were as follows: The value of L* and a* were small and the b* value was large. The glossy rates (G_S75°) of outer leaf and head surface leaf of ‘Yuryoku’ were higher than those of ‘Kinsyu’. The touch-angles of water drop on outer leaf and head surface leaf of ‘Yuryoku’ were smaller than those of ‘Kinsyu’. There were no large differences between ‘Yuryoku’ and ‘Kinsyu’ except that the weight of ‘Yuryoku’ was a little lighter than ‘Kinsyu’. These results suggested that bloomless is the distinguishing characteristics of ‘Yuryoku’ and potentially useful to reduce the chemical application.
