hydrotropism
/hʌɪˈdrɒtrəpɪz(ə)m
/noun [mass noun] Botany
The growth or turning of plant roots towards or away from moisture.Such seedlings behaved identically to seedlings grown on uncovered filter paper and, hence, any possible effects of hydrotropism were eliminated....
- Our experiment proved that hydrotropism really does exist, and watering the plants differently affects root growth.
- These analyses indicate that the application of new genetic screens for dissecting complex signaling phenomena such as hydrotropism is promising.
