| Abstract:
There are now a range of horticultural cladding plastics that alter the spectral balance of sunlight reaching the crop. We studied the responses of a range of horticultural crops to such plastics. A plastic which increased the ratio of red: far red reaching the crop provided effective growth regulation in many crops, but reduced growth is clearly undesirable in crops where biomass yield is the key agronomic output. | |
