The commercial significance of secondary infections of lily symptomless carlavirus (LSV) to commercial Lilium cut-flower producers was assessed by comparing growth of plants and quality of blooms produced from bulbs of eight Asiatic and two Oriental hybrid cultivars both infected and free from infection with LSV. In comparison to LSV-free plants, LSV-infected plants grown under Tasmanian commercial cut-flower production conditions had decreased stem length (mean of 8.5% and 10.4% decrease across cultivars in each of two experiments; P = 0.007 and < 0.001) and fresh weight (18.8% and 23.4%; P = 0.008 and 0.004). Bud size was significantly decreased in one experiment (12.3%; P = 0.001), while bud number and vase life were not affected (P = 0.05). LSV-infected plants grown in a temperature controlled glasshouse had decreased stem length (15.8%; P < 0.001) and petal length (8.7%; P = 0.001) but petal width and bud number were no different to LSV-free plants (P = 0.05). The characters considered to be of greatest economic importance to cut flower producers (viz the number of inflorescences per stem, flower quality and vase life) were not or were only mildly affected by LSV-infection in any cultivar and unlikely to be of major commercial concern.
