Seedling development among reciprocal FI hybrids and their parents, Lotus comiculatus and L renuis, were studies using a simple method of measuring cotyledon area. Cotyledon area attached to the plant could be measured with simple rapid method. Cotyledons expanded very rapidly during the first week, then slightly expanded until maximum size was reached around 3 weeks after emergence. Cotyledon area upon emergence was correlated with seed size (P=0.05), but after emergence there was a divergence in cotyledon expansion rate. Rapidity of photosynthetic area development was determinant factor for seedling growth of trefoil species. 2 $\times$ m2 and 1 $\times$ m2 among the hybrids promised the possibility increasing seedling vigor of birdsfoot trefoil.

Cotyledon and leaf development of six important forage legums were compared to study their contribution to the seedling growth, Cotyledons of forage legumes expanded their size rapidly during one week maximum size was reached and entered senescence. Larger seeds produced greater colyledon area, and speed of colyledon expansion was closely associated with seedling growth. Earlier onset leaf production and earlier leaf development were major determinant factor initial seedling growth. Alfalfa and red clover which have larger seeds were good in seedling vigor with larger photosynthetic area. Alsike clover and white clover with small seeds showed also good seedling vigor, as they developed leaves early with relatively high photosynthetic rate. On the other hand, though lespedeza has heavy seeds, its seedling vigor was very poor with slow photosynthetic area development and low photosynthetic rate.

Nihonbuyo(日本舞踊), a typical traditional Japanese dance, began with kabuki dancing and formed many schools, and was managed by Iemoto system. Iemoto(家元) is the head family of a school of a traditional Japanese art. Iemoto(家元) existed after the establishment of the ancient family system, and it was established as a system during the modern feudal period. Especially in Nihon Buyo, the Iemoto system has developed greatly since the modern era. Iemoto System has has contributed greatly to the succession of traditional arts and has been considered one of the characteristics of Japanese society. Basically, Iemoto system considers it the best authority to pass on the skills of excellent teachers without any distortion. It has various forms depending on the field and the school, but it is an organization with a family structure similar to that of a family with Iemoto at the top. In this article, I examined the establishment and background of the Nihonbuyo and considered the succession of the fame and authority of Iemoto through the system of succession. There are so many schools in the Nihonbuyo world that it is said to be a school kingdom. These schools were divided into kabuki actors, choreographers, female entertainers, ChiutaMai dance(地唄舞) and new dance styles, and the aspect of the Iemoto system was examined through the background and characteristics of each school. While Iemoto system has a positive aspect of inheriting the tradition, there are also many negative criticisms in the art world, such as rigid organizational management, the products of feudal society, the power of Iemoto, and the stalemate of arts. Nevertheless, in a Japanese society that places importance on tradition, the landlady system will not disappear easily. In fact, today, when there are many different art genres in common, young dancers are starting to challenge themselves along with self-examination of Iemoto in order to make the best use of traditional art. We hope that through consideration of the Japanese housekeeping system, it will become a place where intangible cultural properties will be re-acknowledged.
