abstract:
Tests for resistance to frost were conducted by means of luminescence and conductometric methods for seedlings both unhardened and hardened within 14 days at various CO2 concentrations (400, 800, 1200 and 1600 ppm). The tests proved that photosynthetic apparatus and cell membranes of seedlings raised at various CO2 concentration are differential in frost resistance.
