The results indicated:0.1 mg/L 2,4-D or 0.1 mg/L 2,4-D+0.2 mg/L KT was optimal to induct the callus of carrot hypocotyls.The majority of the callus induced on the medium containing 0.1 mg/L 2,4-D regenerated embryoid,whereas,the callus induced on the medium containing 0.1 mg/L (2,4-D)+0.2 mg/L KT produced adventive buds.During the growth of regenerated plant,MS medium is available for rooting of seedling,and seedling regenerated on B5 medium must be placed on the B5 medium containing 0.1% IBA to develop root.

试验结果表明：0 1mg/L2，4 D或0 1mg/L2，4 D+0 2mg/LKT的激素组合有利于胡萝卜下胚轴的愈伤组织诱导；在0 1mg/L2，4 D的培养基上形成的愈伤组织主要以胚状体的形式再生，而在含0 1mg/L2，4 D+0 2mg/LKT激素组合的培养基上形成的愈伤组织主要以发生不定芽的方式再生；再生过程中，B5基本培养基上的苗子不易生根，需要附加0 1mg/L的IBA，而在MS培养基上苗子可直接形成根。

The underground root systems and the plenty of adventive roots growing on basis trucks can greatly reduce soil erosion by reservoir water. The 1 m×1.5 m allocation density of the Salix viminalis showed the best protection, and sediment yield was 8.64 kg/m^2, which decreased 74.38% compared to CK.

柳树根系及主干基部长出的大量不定根，可减缓水库水流对滩地土层的冲蚀，以青刚柳1m×1.5m密度配置的防护效果最好，冲蚀量仅8.64kg/平方公尺，比对照减少74.38%。

His advisement is all right in theory,but not for beening took root.

他的建议在理论上可以，但不能付诸实现。

A moderate amount of organic materials like compost will help amend and aerate the soil for better root growth.

施适量的有机肥，像堆肥会改善土质，提高土壤的透气性，这样有利于植物根部的生长。

There is a great quantity of aerenchyma and secretory canals distributed in root, stem and leaf .

根、茎、叶中均有发达的通气组织和分泌道分布。

The discussion addresses the relationship between adventitious root,their internal aerenchyma formation and the flooding tolerance of plant.

根据实验结果，本文重点讨论了不定根的发生及其内部通气组织的形成与植物耐淹能力间可能的联系。

Finally, cell wall degraded and aggregated together, which results in gas spaces formation in a radial direction.3. Aerenchyma formation appeared to be a form of nonapoptotic programmed cell death in the middle of root cortex.

3稻根内通气组织形成的实质很可能是位于内皮层和外皮层之间的皮层细胞发生非凋亡的程序化细胞死亡形成的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
