What are the morphological characteristics of the blueberry root system?
What kind of characteristics do blueberry roots have? Please introduce them. The blueberry root system has no root hairs. For this reason, the absorptive capacity of the blueberry root system is much smaller than that of root systems with root hairs. Its absorption area is only 1/10 that of a wheat root system of the same size with root hairs. The blueberry root system is fine and fibrous, and before branching the fine roots are straight...

The blueberry root system has no root hairs. For this reason, the absorptive capacity of the blueberry root system is much smaller than that of root systems with root hairs. Its absorption area is only 1/10 that of a wheat root system of the same size with root hairs. The blueberry root system is fine and fibrous, and before branching the fine roots are 50-75um in diameter.
It is worth noting that almost all fine roots of blueberries are colonized by endomycorrhizal fungi, thereby overcoming the difficulty blueberries face in absorbing water and nutrients because their roots have no root hairs. In recent years, numerous studies have proven that colonization by mycorrhizal fungi is beneficial to blueberry growth.
The main part of the lowbush blueberry root system is the rhizome. It is estimated that about 85% of the stem tissue of lowbush blueberry is rhizome. Adventitious buds sprout on the rhizome and form shoots. The rhizome is generally monopodial, 3-6mm in diameter. The rhizome branches frequently, forming a dense (interwoven) network structure in the soil layer 6-25mm below the surface. Newly formed rhizomes are generally pink, while old rhizomes are dark brown and suberized. The root system of lowbush blueberry is distributed in the organic matter layer of the upper soil.
