heliotropism

Some flowers exhibit heliotropism, changing orientation to follow the sun.

Leaf heliotropism is the solar tracking behavior of plant leaves.

Heliotropism is a response to blue light.

(Note that, in actuality, there is no evidence for Sunflower heliotropism.

Several hypotheses have been proposed for the occurrence of heliotropism in flowers:

Another of his works, Heliotropism, discussed man's recognition of the divine will and conformity to it.

Jim did not analyze the matter; his knowledge of photosynthesis and of heliotropism was sketchy.

In their bud stage, sunflowers face and track the sun in its motion across the sky, a behavior called heliotropism.

A. P. de Candolle called this phenomenon in any plant heliotropism (1832).

I'll bet that, if she has ever heard of heliotropism at all, she thinks of it as a plant "reaching for the light."

Heliotropism, experiments on.

Roots, heliotropism of.

A heliotropic plant would do just that-but I'll bet she doesn't know heliotropism from second base.

-on heliotropism.

Yet other species (notably sunflower) are capable of reorienting their leaves throughout the day to optimize exposure to the Sun: this is known as heliotropism.

Phototropism was originally called heliotropism, or bending toward the sun, until scientists found out that plants would bend toward light in general, not just sunlight.

Romanes' paper on the effect of intermittent light on heliotropism was the "Proc.

The uniform alignment of the flowers does result from heliotropism in an earlier development stage, the bud stage, before the appearance of flower heads.

In general, flower heliotropism could increase reproductive success by increasing pollination, fertilization success, and/or seed development, especially in the spring flowers.

They demonstrated no diurnal heliotropism but strong seasonal heliotropism.

Heliotropism is the diurnal motion or seasonal motion of plant parts (flowers or leaves) in response to the direction of the sun.

Floral heliotropism is not necessarily exhibited by the same plants that exhibit leaf heliotropism.

Wiesner's papers on heliotropism are in the "Denkschriften" of the Vienna Academy, Volumes 39 and 43.)

He wrote a popular article on Loeb's experiments in chemical fertilization, and with Loeb wrote on heliotropism in plants and animals.

I did not attempt to rub the reader's nose in the mechanics of heliotropism or why it would develop on Mars because she had been so insistent on not being "too technical."
