          2018/11/12      view:

                The influence of humidity in potato tissue culture mainly has two aspects: one is the humidity condition in the culture container, the other is the humidity condition in the culture room.

                The humidity in the culture vessel is mainly affected by the medium, and the relative humidity can reach 100%.While the humidity of the pure have very big change, it can affect the medium evaporation, generally require relative humidity of 45%, the pure high humidity is low are not conducive to the growth of the cultures, low medium water loss caused by dryness, thus changing the concentration of the medium components, make higher osmotic pressure, affect the growth of cultures and differentiation, too high and will cause the mixed bacteria, resulting in a large number of infections.

                The growth of the seedlings is fast, but the frequency of the glass is higher. In general, the more materials that are developed in the unit volume, the faster the growth of the seedlings, the higher the glass. So the basic point of avoiding the glass is to pay attention to the quality of the flat and the number of plants in the bottle, and the next new batch of seedlings to ensure humidity, can sprinkle some water, or use air humidifier to increase the humidity, when the top bottle mouth of the later top bottle should control the water, avoid the glass.
