  • These Experiments were carried out to test the possibility of produciilg taro earlyplanting culture growing them in polyethylene vinyl house and/or polyethylene tunnneland/or polyetllylene mulching without any supplenmentary heat. Out of various combin-ation of the method of using polyethylene film, Plenty more of taro in polyetllylenehouse+tunnel+mulching on the 5th of March showed the clear possibility that tarocould be harvested on middle of july, which was harvested 3 months earlier thanwhen growing in the open culture . Therefore, it is concluded that taro could be grownas an early crop by using polyetlene film.

  • In order to produce young leaf of butterbur(Petasites japoflicus MAX.) in early spring, the planting date and relationship between abscisic acid(ABA) content and dormancy were investigated. Under open field condition, the dormancy of rootstock was initiated in the beginning of October, was the deepest in the middle of November and was completely broken in the end of December. When those periods were converted by the low accumulation hour below 5$^{\circ}C$, 900 hours were required approximately. This means that the rootstock needs for dormant breaking necessitates under the low temperature. In relationship between growing period and ABA content, the ABA in root-stock did not exist during maximum growing period, from April to September. This means that the ABA together with other substances in rootstock can be transferred to the shoot part with sprouting. While shoot part withered by decreacing the open field temperature since October, the ABA intiated to exist in rootstock. This means that the ABA in the shoot part can be transferred to the rootstock part. Therefore, it was concluded that the ABA which has been known that inhibiting growth and inducing dormancy was closely related with dormancy of rootstock.
