Why do some plants bloom first and then grow leaves

The plants we often see generally grow leaves first and then bloom, but like plum and magnolia, they bloom first and then grow leaves. What is the rationale for this?

To illustrate this problem, we have to start with the structure of flowers and leaves. Generally speaking, trees that bloom first and then grow leaves, most of their flowers and leaves have grown in the autumn of the previous year, but they are wrapped in buds, and you can pick a bud after the leaves have fallen, and dissect it to see clearly. In spring, when the temperature gradually rises, the parts slowly grow, forming a phenomenon of flowering and long leaves.

However, the temperature conditions of the plant organs to the environment are different, such as the leaf buds and flower buds of the peach tree have similar temperature requirements, so the flowers and leaves are almost open at the same time, while the plum and magnolia are somewhat different, their flower buds are lower than the temperature required by the leaf buds, so the flower buds gradually grow and bloom first, and then the leaf buds slowly grow. Therefore, there is the phenomenon of flowering first and then growing leaves.

Most of the plants you said first grow leaves and then bloom, generally not deciduous ones, on the basis of old leaves, and then rise a little core Ye, such as camphor trees, after flowering first every year, the long leaves are deciduous plants, like the forsythia in your **, bellflowers, wisteria, and peach blossoms, pear blossoms, paulownia flowers, red leaf plums, cherry blossoms, and so on.

For example, there are magnolias, magnolias, plums, spring, kapok, birch, plum blossoms, cherries, cherry blossoms, weeping willows, mountain peaches, wheat plums and so on. These plants all bloom first and then grow leaves.

The plants that bloom first and then grow leaves are, bauhinia, magnolia, kapok, plum, cherry blossom, other flowers, etc., among which the other side flower is the most famous, it has the romantic copy of "the other side of the flower, open the other side, only see the flowers, do not see the leaves".

The most famous plant that blooms first and then grows leaves is the other flower, which is also known as Lycoris. Plum blossoms and magnolias are plants that bloom first and then grow leaves. The flowers of plants that bloom first and then grow leaves are beautiful.

Spring flowers, plums, magnolias, cherry blossoms, bauhinia, forsythia, these flowers are particularly beautiful, but the special place is that they bloom first, and then they will grow leaves.

Plants that bloom first and then grow leaves include plum blossoms, cherry blossoms, bauhinia flowers, spring flowers, and magnolia flowers, all of which bloom first and then grow leaves.

Most plants grow leaves before flowering, and these plants bloom first and then grow leaves: plum blossoms, spring greetings, wax plums, magnolia and other flowers.

The growth process of plants is different, and the varieties of plants are different, so there are also plants that bloom first and then grow leaves.

Forsythia, spring flowers, plums, pear blossoms, bell flowers. These plants bloom first and then grow leaves.

Spring peach blossoms, pear blossoms, and spring flowers all bloom first and then grow leaves.

Flowering first and then growing leaves, because flowering and long leaves are the role of flower buds and leaf buds respectively, and the temperature required by flower buds is lower than that required by leaf buds, so when the climate picks up in spring, the climate in early spring meets the needs of flower buds, and the plants will bloom first, and then as the temperature rises, the growth needs of leaf buds are met, and flowers will grow leaves.

Flowers that bloom first and then grow leaves are common plum blossoms, plum blossoms, magnolias, spring flowers, etc.

Cultivation conditions of plum blossoms.

1. Soil. Although the plum blossom is not very strict with the soil, it is also necessary to choose the loose soil and fertile texture, and do not often irrigate in the bonsai, the excess water roots are difficult to absorb, and the drainage is inconvenient, and the roots are easy to rot. There is a market for cultivating plum blossoms that can be purchased.

2. Temperature. Plum blossoms bloom in winter, this is the season when it grows most vigorously, although it is not afraid of severe cold, but it does not mean that it does not need light, if the light is not sufficient, it will slow down photosynthesis, will not develop well, and the amount of flowering will be reduced. It likes to be moist, so keep it ventilated if you keep it inside.

Whether the plant blooms first or grows leaves first is mainly due toFlower buds or leaf buds have different requirements for growth temperaturesTherefore, the temperature required for the growth of flower buds of plants that bloom first and then grow leaves is relatively low, while the temperature required for leaf buds is relatively high; Plants that grow leaves first and then bloom have a relatively low temperature for leaf bud growth, and the temperature in early spring has met its growth needs. So it grows leaves.

Plum blossoms, spring greetings, wax plums, magnolia and other flowers are the first to bloom and then grow leaves, the reason for the formation of this phenomenon is that their flower bud differentiation is carried out in the summer of the previous year, after the formation of the flower buds into dormancy, the next spring can bloom; At the same time, because the temperature required for the growth of flower buds of these flowers and trees is lower than that required for the growth of leaf buds, in the case of low temperature in early spring, the flower buds grow first and open, and when the temperature rises, the leaf buds begin to germinate, forming the phenomenon of first flowering and then leaves.

If the temperature required for the growth of the leaf buds and flower buds is about the same, the phenomenon of flowers and leaves blooming together.

Who are you reading the book twice? There's no reason to be more violent. My heart is like we imagined to provoke him.

Most flowers grow leaves first and then bloom, but flowers and trees such as plum blossoms, plum blossoms, magnolias, and spring greetings bloom first and then grow leaves. Because their flower bud differentiation takes place in the summer of the previous year, the flower buds go dormant and can bloom the following spring. And because the temperature required for the growth of flower buds of these flowers and trees is lower than that required for the growth of leaf buds, the temperature of early spring has met the needs of their growth, so the flower buds gradually expand and open.

But at this time, the temperature can not meet the needs of the growth of leaf buds, so when the temperature gradually rises to meet the needs of its growth, the leaf buds begin to germinate, so there is a phenomenon of first flowering and then growing leaves. If the temperature required for the growth of flower buds and leaf buds is about the same, in spring, the flowers and leaves will open almost at the same time, such as peach blossoms, begonias, etc.

For example, Erqiao magnolia, this is because plants need to consume a lot of energy to flower, so some plants have more nutrients after a whole winter of nutrient accumulation, so they bloom first, complete the process of reproduction, and then grow new leaves in vegetative growth.

Whether a plant blooms first or grows leaves first directly depends on the flower buds.

or the growth temperature requirements of leaf buds. Plants bloom first and then grow leaves because the temperature required for the growth of flower buds is relatively low, and the temperature required for leaf buds is relatively high, and when the flower buds grow, the leaf buds are still latent and cannot grow until the temperature rises further.
