基质理化性质对铁皮石斛组培苗移栽成活及生长的影响
Effect of Matrix Physical and Chemical Properties on Transplanting Survival and Growth of Tin Caulis Dendrobium o f f icinale Kimura et Migo Somaclone
摘要
Abstract
The physical and chemical properties of matrix are the key factors for the somaclone took root trans-planting survival .Through the ratio of different proportions of various matrix ,determination of matriz physical and chemical properties of Dendrobium of f icinale Kimura et Migo and survey the somaclone indices such as survival rate were studied .The results showed that the Dendrobium of f icinale Kimura et Migo somaclone took root in the formula of the matrix was suitable in the physical and chemical properties of the formula for lum-ber :peat :pearlite was 1 :2:1 ,its bulk density was 0 .11 g·cm-3 ,60 .58% of the total porosity and capillary po-rosity were 14 .25% and 71 .56% ,the capillary porosity size void ratio was 1 :1 .3 .Matrix of NPK nutrient con-tent were 0 .059 ,0 .016 and 0 .153 g·kg-1 ,pH value was 6 .8 ,the conductivity was 0 .90 Ec .The survival rate , rooting and growth of Dendrobium of ficinale Kimura et Migo somaclone grew in sawing wood ,peat ,perlite of 1:2:1 matrix which were significantly higher than other matrix formula .It was more suitable for the Dendrobi-um of f icinale Kimura et Migo somaclone growth of cultivation matrix .关键词
