Question

Почему у томатов и винограда рекомендуется обрезать боковые побеги? Почему весной сок у берез и кленов сладкий? Пожалуйста помогите!

Answer 1

1.Чтобы питательные вещества не тратились на мелкие отростки, а все расходовались на плоды.

2. Причиной этому гидролиз крахмала, который был апасен внутри дерева как запас питания. весной, когда фотосинтеза еще нет, корни начинают качать воду, а по пути в нее добавляются минеральные соли и продукт гидролиза крахмала - глюкоза (в основном), которая необходима распускающимся почкам ля питания, пока они не смогут начать синтез сами.

Why is it recommended to prune the side shoots of tomatoes and grapes?

Pruning the side shoots of tomatoes and grapes is recommended for several reasons:

1. Promotes better fruit production: By removing the side shoots, the plant's energy is directed towards the main stem and developing fruits. This allows for better air circulation and light penetration, which can result in larger and healthier fruits [[1]].

2. Controls plant growth: Tomatoes and grapes are vigorous growers, and if left unpruned, they can become dense and tangled. Pruning helps to control the growth of the plant, making it easier to manage and harvest the fruits [[2]].

3. Reduces disease risk: Pruning helps to create space between the plants, allowing for better airflow and reducing the risk of diseases such as fungal infections. It also makes it easier to identify and remove any diseased or damaged parts of the plant [[3]].

4. Improves fruit quality: Pruning can improve the quality of the fruits by ensuring that the plant's resources are focused on fewer fruits, resulting in larger and sweeter produce. It also helps to prevent overcrowding, which can lead to smaller and less flavorful fruits [[4]].

Why is the sap of birch and maple trees sweet in spring?

The sap of birch and maple trees is sweet in spring due to a natural process called sap flow or sap rising. During winter, these trees store starches in their roots as a source of energy. As temperatures rise in spring, the starches are converted into sugars and transported through the tree's vascular system to support new growth and the production of leaves and flowers [[5]].

The sweet sap is a result of the high sugar content, which is essential for the tree's growth and development. This sap flow can be tapped and collected to make maple syrup or birch syrup, which are popular sweeteners.

It's important to note that not all trees produce sweet sap in spring. The sweetness of the sap is specific to certain tree species, such as birch and maple, which have adapted to this process as a survival mechanism.
