    摘要： To provide an axially asymmetric optically active biarylphosphorus compound that can easily produced without the step of optical resolution which was almost indispensable in conventional methods.
    Solution:
    A method for producing an axially asymmetric phosphorus compound represented by the general formula (1), comprising a cycloaddition reaction of a compound having a triple bond with the use of a catalyst containing rhodium metal and an optically active bisphosphine.

    (In the formula, J is an oxygen atom, a sulfur atom or BH 3 ; R 1 and R 2 independently are an alkyl, cycloalkyl, aryl, alkoxy and aryloxy group; a1 and a2 independently are 0 or 1; R 3 to R 10 independently are an alkyl, cycloalkyl, aryl, alkoxy and aryloxy group; two among R 3 to R 10 may form a ring; and * is axial asymmetry.)

    摘要： The present invention provides a drill for making a dilled hole having a high circularity. The axial asymmetric edge drill has a chisel portion formed in the tip center so that the chisel portion center matches with the drill shaft center. At least one of the cutting edges is in an axial asymmetric position with another cutting edge across the drill shaft center. The outline of the edges of the drill forms a circular arc.

    摘要： Problem] To provide a technique whereby, in cultivating a crop, factors relating to differentiation into flower buds and leaf buds, sprouting, flowering and fruiting, growth of young shoots, etc., are regulated. For example, the invention addresses the problem of regulating the growth of a crop so that leaf buds sprout in tandem with the sprouting of flower buds and flowering and fruiting are repeated under fresh foliage. [Solution] A plant cultivation method which comprises environmentally stimulating a plant to regulate differentiation into flower buds and/or differentiation into leaf buds. In a typical embodiment, the plant is held in an environment at a temperature of 16-40°C at a photoperiod of 8-13 hours immediately after harvesting fruits. As another environmental stimulus, the plant is held in, for example, an environment at a temperature of 3-7°C. As still another environmental stimulus, the plant is held in, for example, an environment a temperature of 16-23°C at a photoperiod of 8-11 hours.
