What shape are apple leaves?

Question 1: What shape are the leaves of an apple tree? apple tree

Question 2: What shape are the leaves of the apple tree? Oval serrated leaves.

Question 3: What do apple leaves look like? The height of deciduous trees in apple trees can reach 15 meters, and it is generally 3-5 meters high under cultivation conditions. The trunk is grayish brown, similar to the color of pear trees, but the bark is delicate, not as rough as pear trees. The old bark has irregular longitudinal cracks or flaky peeling, and the branchlets are smooth. The leaf sequence is simple and alternate, oval to ovoid, and the leaf margin is serrated. Corymb with white petals, pink buds, 20 stamens and 5 styles. Fruit is a kind of kernel, and its color and size vary with varieties.

Question 4: What shape are the leaves of the apple tree? An ellipse has a tip.

Question 5: What shape is the apple tree? At present, there are four main planting patterns of apple trees in production:

Plant spacing is about 2x4m, with 83 plants per mu, and free spindle pruning is adopted;

The plant spacing is about 1.5x3.5 meters, and about 127 plants are planted per mu, and unilateral tree pruning is adopted;

The plant spacing in mountainous area is about 3x4 meters, with about 55 plants per mu, and pruning is carried out in the form of small crown and sparse layer.

Sparse planting gardens with row spacing of 4 × 5 meters or more can adopt tree trunk sparse type, delayed open heart type or weeping willow tree type.

Question 6: What does an apple tree look like? ① Morphological habit

Apple trees, deciduous trees. The height of the tree can reach 15 meters, and it is generally about 3 ~ 5 meters under cultivation conditions. The trunk is grayish brown, the old bark has irregular longitudinal cracks or flaking, and the branchlets are smooth. Simple leaves alternate, oval to ovoid, with serrated leaves. Corymb, white petals, pink buds, 20 stamens, 5 styles. Fruit is a kind of kernel, and its color and size vary with varieties. Like light, like slightly acidic to neutral soil. It is most suitable for sandy soil with deep soil layer, rich organic matter and good ventilation and drainage.

Reproduction by grafting. There are two kinds of rootstocks: arbor rootstocks and dwarf rootstocks. Commonly used tree rootstocks are Juglans mandshurica, Haitang Xifu and Vitex negundo, and dwarf rootstocks are mainly imported from Britain. Wide rows and close planting are adopted, and the behavior is north-south. The soil in southern China is planted before freezing in autumn and winter, and in northern China it is planted during thawing in spring. Apple is weak in self-fruiting, so pollination trees must be arranged when planting.

Question 7: Apple leaf information: Introduction to the efficacy of apple factory: Apple leaf (southern Yunnan herbal medicine)

The source is the leaves of Rosaceae apple, and the plant morphology is detailed in apple strips.

The Latin name is apple

Apple trees in the shape of animals and plants, up to 15 meters. Branchlets are densely tomentose when they are young, and old branches are purple-brown and glabrous. Leaves alternate, petiole long 1.5-3 cm, pubescent; Stipules lanceolate, entire, caducous; The leaf blade is oval, ovoid to wide oval, 4.5-10cm long and 3-5.5cm wide, with circular serrations on the edge and pubescence on both sides when young. Flower bisexual; Corymb with 3-7 flowers, clustered at the top of branchlets; Pedicel 1-2.5 cm long, densely tomentose; Flowers white or pinkish, 3-4 cm in diameter; Stamens 20; Style 5. The fruit is oblate, more than 2cm in diameter, the apex often rises, the calyx column sinks, the calyx lobes persist, and the fruit pedicel is short and thick. Flowering in May and bearing fruit in July -65438+ 10.

Question 8: What is the shape of the leaves? (Name three or more) Leaves are vegetative organs that grow on the stems of plants and are responsible for producing nutrients. Every leaf is a small green chemical plant. There is something called chlorophyll in the leaves. They are the "workers" of Ye Chemical Plant. Chlorophyll uses sunlight, carbon dioxide in the air and water absorbed from roots to produce oxygen, starch and glucose. Glucose can be dissolved in water and transported to all parts of plants at any time to meet the needs of plant growth. Starch is temporarily stored in leaves and cannot be transported until evening. Leaves are usually green because they contain chlorophyll. Most of the leaves are flat, which is beneficial to receive sunlight to the maximum extent.

The basic structure of leaves of plants is the same, which is composed of leaves and petioles, and there are veins on the leaves. Because of adapting to different environmental conditions, the shapes of leaves are different. A leaf with only one leaf on each petiole is called a single leaf, such as the leaves of sunflower, corn and mulberry; Two or more leaves on each petiole are called compound leaves, such as Sophora japonica leaves, mimosa leaves and peanut leaves. Some leaves are shaped like eggs and are called oval leaves, such as leaves of apple trees and mulberry trees; The shape of leaves is a spear-shaped head, which is called lanceolate leaves, such as willow leaves and bamboo leaves; Some leaves are shaped like a human palm, called palm leaves, such as maple leaves and castor leaves; Some leaves are shaped like an open folding fan, called fan-shaped leaves, such as ginkgo biloba leaves; Some leaves are shaped like ribbons, which are called banded leaves, such as leaves of corn and green bristlegrass; Some leaves are shaped like hearts, called heart-shaped leaves, such as sweet potato leaves and morning glory leaves; Some leaves are round, called round leaves, such as cotinus coggygria leaves; Some leaves are sharp, like needles, called needle-like leaves, such as pine leaves; Some leaves are like scales, called scales, such as the leaves of Platycladus orientalis. There are many plants with leaves of various shapes. For example, the leaves of onions are like tubes, which some botanists call tubular leaves. Liriodendron is called "Liriodendron" because its leaves are shaped like a tulip, and because its leaves are particularly like jackets that people used to wear, it is also called "Liriodendron".

Question 9: What are the symptoms of apple trees and their leaves? The diseased trees are distributed in patches or rows, and germinate later in spring than healthy trees. After the leaves are unfolded, the top leaves are clustered and the middle and lower branches are exposed. The leaf margin is rolled up, brittle and hard, and it is willow-like. Some veins are green, but they are yellow. New shoots have short internodes and diseased branches are easy to die. Flowers are few and small, and fruits are small and deformed. Old and sick trees are almost all lobules, with empty crowns and low yield.

Pathogen This disease is caused by zinc deficiency, and it is a physiological disease.
