Pollution and Control Measures in Plant Tissue Culture in Orchid Plant

Contamination is a phenomenon that often occurs in the operation of plant tissue culture,and it is also one of the three major problems in plant tissue culture.Compared with browning and vitrification,contamination is more likely to occur,which brings great harm to scientific research and production practice.Its appearance will greatly affect the normal growth and differentiation of tissue culture materials,and will reduce the yield of cultivated plants to a certain extent.Therefore,we cannot underestimate any step in the tissue culture operation.This study summarized the reasons for its occurrence and how to formulate prevention and control measures based on recent research combined with the actual situation.
