heliotropic

Heliotropic flowers track the sun's motion across the sky from east to west.

The buds are heliotropic until the end of the bud stage, and finally face East.

Heliotropic Hypothesis is the process when social systems evolve toward the most positive images they hold of themselves.

Beans are a heliotropic plant, meaning that the leaves tilt throughout the day to face the sun.

It is nationally significant as the first institution designed for heliotropic treatment of children suffering from tuberculosis.

Sales are up almost 40 percent over last year, and as a result, the 30-minute tan has all but supplanted the distasteful heliotropic kind.

Sunflowers in their blooming stage lose their heliotropic capacity.

In general, feeder roots tend to show both positive hydrotropism and negative heliotropic behavior.

Here a little work in the paddy-fields suffices to maintain a heliotropic, pullulating subsistence.

Heliotropic Feat.

The buildings thinned out and they saw some of the heliotropic Martian vegetation, spreading greedy hands to the Sun.

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

Their heliotropic motion is a circadian rhythm, synchronized by the sun, which continues if the sun disappears on cloudy days.

If you ever come across heliotropic or apheliotropic aerial roots on a plant not valuable (but which should be returned), I should like to observe them.

Other skin manifestations involve periungual telangiectasias and a heliotropic (purple) rash over the upper eyelids.

What had started years before as a sifting of new spores, a heliotropic tug on a few of the existing data plants, had become the dominant paradigm.

The heliotropic motion of the bud is performed by the pulvinus, a flexible segment just below the bud, due to reversible changes in turgor pressure, which occurs without growth.

It eats from dawn until sunset and sleeps through the night, and since it is heliotropic - with its head always pointing towards the sun - it also functions as a timepiece.

Maskull crosses the sea by maneuvering a many-eyed, heliotropic tree and reaches Matterplay, where much to his amazement a plethora of life-forms alongside a magical creek materialize and vanish before his eyes.

Some solar tracking plants are not purely heliotropic: in those plants the change of orientation is an innate circadian motion triggered by light, which continues for one or more periods if the light cycle is interrupted.

These 'binding' scenes, and the heliotropic swamp plants appearing in them, evoked the necessity of discerning and revealing the underlying harmony, the origin of all manifest forms, that re-connects the dispersed and separate-seeming fragments of everyday experience.
