What is the effect of water on flower bud differentiation?

Moderate drought is beneficial to promote flower bud differentiation. Proper control of water before flower bud differentiation, watering less or stopping watering for several times can inhibit or delay the growth of stems and leaves, advance and promote the formation and development of flower buds.

The relationship between flower color and water is close, generally when the lack of water, the flower color becomes thicker, such as the white peach variety of rose, in the case of lack of water, it often becomes milky yellow or light peach color. Chrysanthemum also has the same situation, when the lack of water, due to the formation of more pigments, so the color becomes thicker.
