Studies On The Epiphytic Microflora And Biological Preservation Of Cut Carnation

The study is based on the theory of Plant Microecology, the epiphytic microflora of cut carnation and the effects of microoganism to senescence were studied, the biological preservation and the physiology of senescence of cut carnation were explored instructively in this paper, and the species of microorganism and biological preparation which can preserve to cut carnation were expected to obtain. The main results are as follows:1 ,This paper reported the effects of microorganism on the tangent plane of stem to senescence in cut carnation during postharvest life. The culture analysis of vase water and tangent plane of stem showed that bacterium was main microorganism in cut carnation during its postharvest life, a total of 32 bacterial isolates were obtained from 30 cut carnation. The different inoculation of bacteria were investigated on flowering status index. The results indicated that the differences of withering degree, flower diameter and vase life among different cut carnation treatment were significant, and six isolates of 32 strains were effective, two isolates were beneficial. The pathogenic bacteria were identified as Clavibacter.2,The primary analysis on the epiphytic bacterium of cut carnation leaf and petal in the same condition were reported, a total of 33 bacterial isolates were obtained from cut carnation leaf and petal by two agar plate culture, among which 13 bacterial strain were identified as Bacillus spp. The metabolites vase solution(5%) of 13 Bacillus strains were investigated on flowering status index, the treated vase life were lower than the contrast,...
