Production Rate of Runner Plants in a Plant Factory with Artificial Lighting as Affected by Crown Diameter of Strawberry Propagules

Use of the appropriate propagule size can maximize propagation rate strawberry (Fragaria × ananassa) transplants in an autotrophic transplant production method, a novel method plant factory with artificial lighting for production. During 90 days after planting initial propagules, cumulative number produced from propagules 5 mm crown diameter (CD5) was greater than those 4 (CD4) or 6 (CD6). Timescales cycles (required timescale to produce new propagules; sum time emergence runners and separation runner plants) first, second, third plants CD5 were 2.1 – 20.7% shorter CD4 CD6. In second plants, increased as decreased; however, decreased decreased. The fluctuation timescales generation smaller After separating their leaves fluctuated less These results indicate that having two are factory.
