What effect does frost have on vine growth?

Frost can be particularly detrimental to vine growth, especially in the spring when new shoots are emerging. When temperatures drop below freezing, the water inside the plant cells can freeze, causing the cells to rupture and leading to significant damage or even death of the new growth. This can result in reduced yields for the season, as the vines are unable to produce fruit if the new shoots and buds are harmed. Therefore, understanding the impact of frost is essential for vineyard management, as it can affect not only the quantity of grapes produced but also the overall health of the vines over the long term.

While some other options might suggest a positive or neutral impact, they fail to acknowledge the potential physical damage that frost poses to the developing parts of the vine. Hence, the detrimental nature of frost on young growth makes the identification of it as damaging the correct choice.
