hydrotropism การใช้

• Auxin participates in phototropism, geotropism, hydrotropism and other developmental changes.
• Other kinds of tropisms include gravitropism, phototropism, hydrotropism, and heliotropism.
• Hydrotropism is when the plant's roots grows toward a source of water.
• This qs, root hydrotropism research has mainly been a laboratory phenomenon for roots grown in humid air rather than soil.
• Its ecological significance in soil-grown roots is unclear because so little hydrotropism research has examined soil-grown roots.
• Hydrotropism may have importance for plants grown in space, where it may allow roots to orient themselves in a microgravity environment.
• The process of hydrotropism is started by the root cap sensing water and sending a signal to the elongating part of the root.
• Hydrotropism is difficult to observe in underground roots, since the roots are not readily observable, and root gravitropism is usually more influential than root hydrotropism.
• Hydrotropism is difficult to observe in underground roots, since the roots are not readily observable, and root gravitropism is usually more influential than root hydrotropism.
• This directional growth can occur via a plant's response to a particular stimulus, such as light ( phototropism ), gravity ( gravitropism ), water, ( hydrotropism ), and physical contact ( thigmotropism ).
