1. Aerenchyma is well developed in mesophyll.

2. Cortex comes to be aerenchyma.

3. The thickness of phellem, aerenchyma , diameter of vessel holes, and the number of vessels are related to the anti-waterlogging character.

4. When cortex aerenchyma began to form, flooding was beneficial to its formation, which could enhance the waterlogging tolerance of annual wild soybean.

5. Anatomical observation of aerenchyma helps understand the growth, distribution, and adaptation of wetland plants to different habitats.

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

6. Wish you will love and make progress everyday!

7. Moreover, M. alternifolia developed aerenchyma and adventitious roots during inundation, with root porosity in the flooded seedlings much higher than that of the control.

8. The aerenchyma was made of broken cell of vascular ray in the roots.

9. Compared with inundatory condition, aerobic condition retarded the formation of aerenchyma of hybrid rice roots and made the cortex sclerenchymatous cells array loosely in conventional japonica root.

10. The crystals exist in parenchyma cells of its petioles. Its petioles have big vessels and much aerenchyma .

11. The present results support the hypothesis that an enhanced cellulase activity is involved in the lysis of cortical cells leading to aerenchyma formation under a waterlogged condition.

12. With the altitude increasing, the thickness of the leaves, palisade and spongy tissue increased, and all of them had well-developed aerenchyma.

13. Soil culture experiment was conducted to study the effect of rice root aerenchyma on root iron plaque by Jiahua 1 this kind of genotype rice.

14. Hydrophytes show certain adaptations to such habitats, notably development of aerenchyma, reduction of cuticle, root system, and mechanical and vascular tissues, and divided leaves.
