| If the soil in the immediate environment is disturbed, as by excessive erosion, positive geotropic growth is stimulated within these lignotubers. |
|
| Also, fresh cut tulips are geotropic and phototropic, meaning that their growth is affected by gravity and light, respectively. |
|
| The radicle, which normally grows downward into the soil, is said to be positively geotropic. |
|
| The result is several large, positively geotropic roots that produce higher-order roots, which may also grow to the same size. |
|
| Zoospores are negatively geotropic and by swimming upwards become concentrated in the water at the surface of the soil. |
|
| In general, plant roots grow downward for as they are positively geotropic and hydrotropic. |
|
| Orbignya cohune is known to be important in the development of the soil profile stems are initially geotropic and buried to depths of one metre during establishment growth. |
|
| In posterior canal BPPV there is usually a brief latency, followed by a geotropic verticalrotatory nystagmus lasting less than 60 seconds. |
|
| Branch roots are of two kinds: long-branching geotropic roots and short-branching apogeotropic roots, which are referred to as coralloid because of their irregular, beady appearance. |
|
| Perhaps there is something about the geotropic, burrowing urge that betrays a kind of deep-seated introspection – a desire to dig, to escape further from reality, to withdraw into a private fantasy world. |
|
| This response is known as a geotropic response. |
|
| Silica distribution in Equisetum hyemale var affine in relation to the negative geotropic response. |
|
| Each spring, as moisture permits, the tuber produces leaves, a root, and a strobilus, and a geotropic new tuber. |
|
| The meristem that gives rise to each new geotropic tuber is exogenous, formed from surface tissue where the leaves and strobili join the old tuber. |
