Effect of Red and Blue Light on Cucumber Seedlings Grown in a Plant Factory

Light-emitting diodes (LEDs) have been regarded as the best artificial source of light for a plant factory. However, effect quality on seedling production in such environments requires further study. On basis practical application cucumber seedlings (Ansha Company) factories, present investigation tracked and recorded specific effects red blue growth by analyzing photo-biological mechanism involved. The parameters, well photosynthetic characteristics seedlings, were measured at different variations quality. results showed that when proportion was higher than light, height leaf size, stem diameter, Dixon Quality Index (DQI), relative chlorophyll content, net rate those experimental group with relatively high light. In case R7B3 (70% 30% light), DQI, 14%, 57%, 22% minimum value, respectively. study analyzed influence during actual provides standardization it.
