马铃薯（Solanum tuberosum L.）在常规光混合营养条件[培养基中含20 g蔗糖/升，光合光子通量（PPF）为70 μ mol·m-2.s-1]和最小通气（MV）条件下以及在光自养条件下研究了'Benimaru'试管苗（培养基中不含糖，PPF低于190 μ mol.m-2-s-1），使用空气扩散过滤器（DV）或强制通风（FV）增强自然通风。FV和DV处理的试管苗鲜重是MV处理的2.4倍。净光合速率和单株干重以FV最高，DV次之。在光自养微繁中，FV比DV具有上级优势。
Growth and net photosynthetic rate of potato (Solanum tuberosum L.) 'Benimaru' plantlet in vitro were studied under a conventional photomixotrophic condition [with 20 g sucrose/liter in the medium and under 70 mumol.m-2.s-1 photosynthetic photon flux (PPF)] with minimal ventilation (MV) and under photoautotrophic conditions (without sugar in the medium and under 190 mumol.m-2-s-1 PPF) with enhanced natural ventilation using an air diffusive filter (DV) or with forced ventilation (FV). Fresh weight of the plantlets cultured in the FV and DV treatments was 2.4 times that of the plantlets cultured in the MV treatment. Net photosynthetic rate and dry weight per plantlet were the highest in FV followed by DV. For photoautotrophic micropropagation, FV was superior to DV.
