The effects of different temperature conditions on Chinese cabbage and kale growth have not been reported recently.Our objective was to evaluate the effects of temperature (14 ± 1℃, 17 ± 1℃, 20 ± 1℃, 23 ± 1℃ and 26 ± 1℃) on Chinese cabbage and kale growth including leaf length, leaf width, and leaf weight.Plants were cultivated in a plant factory and the leaf samples were collected at two different sampling times (2& 4 weeks after transplanting of seedlings) to measure their growth parameters.The results showed that leaf length of kale was highest under 26 ± 1℃ at 2 weeks and 4 weeks while leaf width of kale was highest under 26 ± 1℃ for 2 weeks and under 23 ± 1℃ for 4 weeks.The leaf weight of kale was greatest under 20 ± 1℃ at 2 weeks and 4 weeks.The results also showed that leaf length, leaf width and leaf weight of Chinese cabbage were simultaneous highest under 23 ± 1℃ and 20 ± 1℃ at 2 weeks and 4 weeks, respectively.However, the growth of leaf length of kale from 2 weeks to 4 weeks was better under 26 ± 1℃ whereas 23 ± 1℃ was better temperature for the growth of leaf width and leaf weight of kale.The growth of leaf length of Chinese cabbage from 2 weeks to 4 weeks was better under 20 ± 1℃ and growth of leaf width and leaf weight of Chinese cabbage were greatest under 17 ± 1℃.Therefore,we concluded that 23 ± 1° and 20 ± 1℃ resulted in the positive effect on Chinese cabbage growth at 2 weeks and 4 weeks after transplanting of the seedlings, respectively.We also concluded that 26 ± 1℃ resulted in the positive effect on kale growth at 2 weeks.Changing different temperature from 2 weeks to 4 weeks might be helpful to improve the leaf's growth parameters.
