WIDE ROW PLANTING: The method of sowing seeds, usually of the same plant, in multiple rows. For example, two or three lines of beans can be planted together, often on a raised row, with deep, wide parallel channels for irrigation.
WIND BREAK: Something to break the force of the wind, such as a hedge, fence, or a row of evergreen trees. Any shelter from the wind.
WIND BURN: A withering or blasting of foliage caused by dehydration due to over exposure to wind. Young foliage is especially susceptible. Foliage seriously affected by wind burn won't recover and even though new leaves may appear, the plant is likely to be weakened.
WINDOW: This is a layer of semi-transparent cells, containing a calcium oxalate, at the tip of a succulent leaf. The window protects the chlorophyll in the plant body from being destroyed by harsh sunlight by diffusing the light before it reaches the chlorophyll, thus enabling photosynthesis to take place.
WIND-ROCK: The destabilizing of a plant's roots by the wind.
WING: A dry membranous expansion or thin extension of any kind, such as that on certain seed capsules or stems, such as the winged seeds of Maple Trees (Acer). Also, one of the two side petals of certain flowers.
