Abstract


Oriental lily (Lillum) ' Sorbonne ( ' Sorboune ' ) , ' Marshal ' ( ' Acapulco ' ) , ' Siberia '(' siberia ') three varieties of material to study Oriental lily shoot tip culture in vitro into the ball Bulblet break dormancy , techniques and methods of Scale Cutting and supporting the production of quality merchandise bulbs . Oriental lily products scales as explants , MS medium and exogenous hormones, tissue culture studies apical meristem differentiation . The results show that : the scales induced the small earners ball the best medium for MS 6 - BA 1.0 mg / L NAA0.2mg / L . The best medium for shoot tips induced differentiation MS 6-BA1.0mg / L NAA 0.5mg / L. 2 light and sucrose concentration , oriental lily in vitro adventitious buds into a ball culture in MS medium . The results show that : the test tubes into a ball optimal sucrose concentration of 75g / L, without light bulb growth conducive . Oriental lily bulbs at 10 ° C , 5 ° C , -1 ° C , -5 ° C four temperature to break dormancy and germplasm conservation tests . The results show that the low-temperature processing of the tissue culture growth is very important , the optimum temperature and time for 5 ℃ for 8 weeks at 10 ° C for 12 weeks , followed by ; tissue culture the best germplasm preservation temperature of -1 ° C The ultra-low temperature for bulb storage . 4 identified through the analysis of the effects of different temperature and humidity and matrix scales germination of different varieties in different parts of the cultivation of small ball , different sowing time of different varieties and different planting training mode of growth of commodity bulbs Scale Cutting method the micropropagation earners ball to commodities bulbs grow into a range of methods and techniques . Through research , scaly outer layer 25 ℃ and RH 80% condition , herbaceous peat : perlite = 2:1 matrix germination effects best varieties is not very different . Early March or early September seedbed Sowing bulbils , bulblets cultivate a circumference of 6-8cm , the fall is more conducive to the growth of small ball , there is the difference between the varieties . In early March sowing the refrigerated balls , November or delay in closing the ball in July of the following year , some of the bulbs to achieve the specifications of the commodity bulbs , and used in the production .
