Result The active component content in phloem was the highest, while, successively, in pith and in xylem.

The phloem, not the xylem, is the supplier of water to flowers and certain other organs.

The positive xylem pressure, often occurs with low transpiration rate, is termed as root pressure.

Both xylem and phloem form a continuous branched system in the whole plant body.

Protoxylem The PRIMARY XYLEM elements that are formed from the procambium first.

Using 6-BA improved the xylem sap exudation rate in root stress, maybe this had some connection with the increase of leaves transpiration.

The cell fiber changing xylem, are also especial much. and metaphloem are also especial good.

Result: The phellem, phloem and xylem of wild bupleurum scorzonerifolium are different from those in the pharmacopoeia .

A root- like structure lacking conductive tissues ( xylem and phloem ) .

It is a key feature in the movement of water through the xylem and through the finer pores of the soil.

Lignified tissues include SCLERENCHYMA and XYLEM.

MethodsThe vessel elements in stem of Sophora japonica were observed by duct of stem's secondary xylem under biomicroscope.

The vascular cambium is located between the xylem and the phloem.

Results There are compound vascular bundles in the xylem of the root of Euphorbia ebracteolata which are distributed as homocentric circles.
