“Our robot has an embedded microcontroller that can process multiple stimuli and direct the growth at a precise location, the tip, ensuring the body structure is preserved,” she says.This fine control of the tip’s direction means the robot can easily navigate unfamiliar terrain, says...
IT is generally agreed that the best method of measuring daylight as a part of the plant's microclimate is to integrate the light with respect to time. The total amount of light received may be noted every day or week according to the time-scale of the experiment. Several light-integrating...
Some plants require specific light conditions, such as short-day or long-day plants, which determine the plant's flowering and fruiting. 3. Phototropism: Light also influences the direction of plant growth. Phototropism is the movement or bending of plant parts towards or away from a light ...
