Abstract:
Taking Dendrobium candidum as test material,the tissue culture seedling of Dendrobium candidum was potted in this experiment,and pine bark and mulberry rod were used as substrate.The effects of potting on growth and antioxidative physiology characteristics dynamics of Dendrobium candidum tissue culture seedling were sutudied in the cultivation process.The results showed that in the cultivation process,the activities of POD,SOD,CAT and the proline content of potted Dendrobium candidum tissue culture seedling with two different substrate was significantly higher than that before transplanting.Also the MDA content was slightly higher than that before transplanting,while the chlorophyll content was lower than that before transplanting.Moreover,the differences of the activities of POD,SOD,CAT were obvious between the two substrates.While the difference of the proline content,the MDA content,the chlorophyll content were not obvious.The survival rate of the Dendrobium Candidum tissue culture seedling was more than 90% of both the substrates,meanwhile,the growth was well.The plant height of the Dendrobium candidum tissue culture seedling was 56.18 cm and 61.42 cm respectively after transplantation two years of the two substrates which was closed to the effect of greenhouse seedbed cultivation.
