Common Mistakes When Using “selenotropism”

FAQ

Frequently Asked Questions

It is a documented but rare and debated phenomenon in botany. Evidence exists for specific plant species, but it is not a common trait.

Heliotropism is growth in response to the sun (solar tracking), while selenotropism is a response to moonlight. The latter is far weaker due to the moon's vastly lower light intensity.

In theory, yes. 'Positive selenotropism' is growth toward moonlight, and 'negative selenotropism' would be growth away from it, though documented examples are extremely scarce.

The phenomenon itself is rare and highly specialized. Most plant growth is dominated by responses to stronger stimuli like sunlight (heliotropism) or gravity (gravitropism).
