Thies study was undertaken to obtain ssome information on the characteristics of growth and seed productivity of different physiological and ecological types of Faba bean, using Japanese (J) and Swedish (S) varieties of middle seed as materials. The experiment was conducted with autumn and spring sowing cropping.The results obtained may be summarized as follows:(1) Japanese variety's amin shoot contributed strongly to the development of branched shoots compared with Swedish one. The former has intergrated Source-Sink relationship as one shoot revealing the deteminate growth habit and the latter has cumulative many Source-Sink units in one stem exhibiting the indeterminate one.These phenomena were similarly found in autumn and spring cropping with two varieties and showed the substantial different characteristics among two types.(2) The chemical content, especially carbohydrate was high on stem before the flowering stage, which decreased accompanying with the flowering. High value was also found at the green pod stage on stem and pod which follwed declination with seed ripening. These variations were similarly found in different cropping seasons with two varieties.Though the degree of declination of the content was high on Japanese variety during the flowering period, it was found on Swedish one in the seed ripening one. The nitrogen content in leaves of Japanese variety was superior to that of Swedish one during former stage. On the contrary, it was contrastively found during later stage. Judging from results it is suggested that the performances of differnet growth habit should be revealed more clearly on middle seed varieties by the difference of Source-Sink balance, critical contnet of carbohydrate in the source and its translocating ability for the sink, and the activity of metabolic nitrogen among two types of Faba bean.
