• Background and Aims Previous studies indicate that the size-controlling capacity of peach rootstocks is associated with reductions of scion water potential during mid-day that are caused by the ...

Premise of the study: Xylem network connections play an important role in water and nutrient transport in plants, but also facilitate the spread of air embolisms and xylem-dwelling pathogens. This ...

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while ...

An embolism in a xylem vessel can be as disastrous to plants as one in a blood vessel can be to a human. Water supply to the leaves is cut off, and cells cannot function properly without water. This ...

The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called ...

With our sustained high summer temperatures plants need a continuous source of water. Water moves from the soil into and throughout a plant delivering water and nutrients via a pipe-like vascular ...

As water travels through the xylem in the stem and leaf, it is being replaced by water taken up by the roots. Photosynthesis produces glucose in the green parts of plants, which are often leaves. This ...
