Key Techniques of Industrial Seedling for Anthurium andraeanum

[Objective] The aim was to study the techniques for the tissue culture,rapid propagation and transplantation of Anthurium andraeanum.[Method] The leaf,leaf stalk,spathe and spadix of the pot flower variety and cut flower variety of A.andraeanum were used as explants,in order to investigate the influences of the explants selection,disinfection conditions and different media on the callus induction,proliferation and rooting.[Result] The leaf stalk of A.andraeanum was the optimum explant,with the highest callus induction rate（78.3%）.The best disinfecting effect could be obtained when the explants was sterilized with 0.1% HgCl2 for 8 min.The optimum media for the callus induction of Ping Champion and MIDORI were respectively 1/2 MS＋1.50 mg/L 6-BA＋0.50 mg/L 2,4-D＋0.10 mg/L NAA and 1/2 MS＋1.50 mg/L 6-BA＋1.00 mg/L KT＋0.10 mg/L 2,4-D,while the optimum media for callus subculture of Ping Champion and MIDORI were respectively MS＋1.00 mg/L 6-BA＋0.50 mg/L NAA＋0.30 mg/L 2,4-D and MS＋0.50 mg/L 6-BA＋0.50 mg/L KT＋0.10 mg/L NAA.It was beneficial for the proliferation and growth of cluster buds while 10%（w/v）of coconut water or banana jam was added to MS medium at the proliferation stage,and the proliferation rate could be increased by 2.83 fold.At the rooting stage,the medium 1/2 MS＋0.10 mg/L NAA＋0.10 mg/L IAA was the optimum medium for rooting,and the rooting rate was up to 100%.[Conservation] The research results will lay a foundation for the establishment of the industrial seedling breeding system of A.andraeanum,and it will be significant for the development of A.andraeanum industry.

Thoughts on the Ways out of Breeding Industry under the Important Task of Ecological Civilization

The difficulties and problems faced by the breeding industry in China are investigated.On the basis of analysis and thinking,combining the requirements of pollution control by breeding and the construction of ecological civilization at the current stage,the ways out for the development of breeding industry under the important task of ecological civilization are proposed:reforming and innovating and firmly establishing a new thinking of healthy breeding;upgrading industries to make them adapted to the new mode of economic development;treating sewage separately to ensure a clean environment;improving information platform and promoting the application of Internet+new technologies;and improving the legal system and forming a new mechanism for breeding pollution control.
