主根

Brown rhizomorph and hyphae can be seen on the seedlings'rhizome, main root and side root while nothing is on the tip of the root.It was found that rhizomorph on the surface of roots would die after inoculation in 90 days in pot.

子实体单生或丛生，出菇至成熟3 d~4 d，单个子实体重20.0 g~62.0 g；小粒咖啡苗的根茎、主根及侧根被茶褐色的菌索和菌膜包裹，而根尖及靠近根尖的侧根上没有菌丝和菌索生长或生长很少；盆栽小粒咖啡苗，在接种90 d后其根系表面的菌索死亡。

Based on the analysis on principal root of the different-differential equation, a parameter design method that can achieve the best transient performance is presented.

通过研究差分微分方程组的主根，给出了能够使得控制系统以最快速度达到稳态的参数设计方法。

The results indicated that:(1) plant height and tillering number decreased, and root length, root surface area, root volume and rootlet number increased under drought stress; straw mulched on surface soil and pig manure mixed in soil could improve the growth and morphological property of rice root, while straw mixed in soil and pig manure mulching had no significant effects;(2) the contents of chlorophylls and the activities of SOD, POD and CAT decreased significantly under drought stress, and straw mulching on surface soil and pig manure mixed in soil could restrain these decreases.

结果表明：①干旱胁迫下水稻株高降低、分蘖数减少，根系则表现出主根伸长、支根增多、根表面积和根体积增加；秸秆表施和猪粪混施可明显改善水稻的生长和根系形态，而秸秆混施和猪粪表施的改善作用不显著；②干旱胁迫下叶片叶绿素含量显著降低，超氧化物歧化酶、过氧化物酶及过氧化氢酶活性均显著下降，秸秆表施和猪粪混施能够在一定程度上抑制这种下降幅度。

Shagbark hickory trees are easy to transplant until about 4-5 feet tall , when a long taproot begins to anchor the tree to the ground with very few lateral roots.

胡桃木易于移植树木直到约4-5英尺高大当主根长开始向地面主播树侧根很少。

But now I see that there was still life at the taproot.

但现在我看到主根还有生命。

With increased P concentration, the taproot length first increased and then decreased subsequently.

随着磷浓度的增加，主根长度呈现先升高后下降的趋势。

Tree that have well develop taproot is well equipped to withstand wind storm.

有粗大主根的树能经得住大风暴的袭击。

I/L of ethametsulfuron separately to the length of taproot and bud, and the fresh weight of taproot.

水培3 d后胺苯磺隆对水稻主根长和芽长的IC50分别为12.61、117.81 ng/L。

Space the plants at random, poking a hole into the soil to accommodate the taproot and lower portion of the body.

太空植物随机皱孔进入土壤，以容纳主根和下部的身体。

Unfortunately, root bound plants are still common because the taproot will bottom-out and start to curve around the bag.

不过这样做也存在问题，根绕在苗上的情况很普遍，因为主根将自下而上出来，并开始盘绕在育苗袋上。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
