摘要

Lisianthus plants intended for cut flower production were grown under a red shade net (ChromatiNet 70%), a blue net (Raschel 70%), and without netting. 'Mariachi' seedlings were transplanted into black polyethylene bags (0.3 to 0.5 cm in diameter) containing red volcanic rock; crop nutrition was done with drip irrigation and Steiner's nutrient solution. Photosynthetically active radiation (PAR) averaged 307.57 μmol/m~2/s with the red net, 202.96 μmol/m~2/s with the blue net and 511.54 μmol/m~2/s without netting. At 92 days after transplanting, when all treatments had buds and it was seen that growth had stopped, the following variables were measured: plant height, stem diameter, number of internodes, SPAD readings, and number of buds. Upon cutting the flower stem (when it had its first open flower), leaf area and nutrient removal were measured. The longest stems, which were also those with greatest diameter, were from plants grown under the red net, followed by the plants grown without netting and, finally, those protected with the blue net. Leaf area was 525 cm2 in plants without netting, 450 cm2 in red-net plants, representing a 16.80% decrease over the former, and 325 cm~2 in the blue-net plants, or 35.71% less than in the plants without netting. The number of internodes for red net and control plants (9.4 and 9.6, respectively) showed significant differences compared to the blue net ones (8.5). The number of buds was affected by the nets; the control treatment averaged 27.58 buds, the red net 21.58 and the blue net 13.79. Days to flower opening varied by the presence of the nets; in the control plants, flowering began at 108 dat, compared to 112 dat and 118 dat for the red and blue net plants, respectively. The results indicate that lisianthus greenhouse production does not require colored nets to increase development and quality.
