Law of fluctuation in plant leaves thickness during day and night

摘要

In order to achieve a precise control of the growth conditions for plants, the measurable properties of plants have been studied by using the measurement instruments. First of all, it is developed that the developed using modern industrial metrology methods to measure the leaves of two kinds of plant for more than 6 months. The measurements made on the measurable properties of plants for establishment of the law of daily variation in plant leaves thickness indicate that the peak takes place at the noon, which is the subject of next research and the mathematic model established in the paper provides an important theoretical basis for further research on control of plants.
