Apple trees, angiosperms, Malus of Rosaceae, deciduous trees, usually trees can be as high as 15 meters, but cultivated trees are generally only about 3-5 meters high. The trunk is grayish brown, and the bark has fallen off to some extent. This kind of fruit is called apple, and it is usually red, but it depends on the variety. The fruit of apple tree is rich in minerals and vitamins and is one of the most commonly eaten fruits. The flowering period of apple trees depends on the local climate, but it is generally concentrated in April-May. Apple is a cross-pollinated plant, and most varieties cannot bear fruit by themselves. Generally, after the apple is planted, it begins to bear fruit in 2-3 years. The length of fruit growth period is generally 65-87 days for early-maturing varieties, 90- 133 days for middle-maturing varieties and 137- 168 days for late-maturing varieties. Generally speaking, the life span of planted apples can reach 15-50 years.
Pear trees, angiosperms, Rosaceae, perennial deciduous fruit trees, trees. The trunk bark is smooth at the young tree stage, and it thickens, cracks or peels off longitudinally with the growth of tree age. The shoots are hairless or have fine hairs, and then fall off; Branches over 2 years old are grayish yellow or even purplish brown.
Winter buds are covered with tile-like scales, generally11-kloc-0/8. Flower buds are plump, brownish red or reddish brown, slightly shiny, and generally mixed buds; The leaf buds are small, sharp and brown. Simple leaves, alternate, serrated, stipules fall off early, tender leaves are green or red, and turn green after unfolding; The leaves are mostly oval or rectangular, and the petioles are different in length. The flowers are corymbose, bisexual, and the petals are nearly round or broadly oval. Cultivars have 3-5 styles, 3-5 chambers, and each chamber has 2 ovules. This kind of fruit is called pear, which has round, oblate, oval and spoon shape. There are two kinds of peels: yellow or brown, and some of the yellow varieties are red; The fruit stalks of Qiuzi pear and Xiyang pear are thicker and shorter, while those of Pak Lei Shali pear and Xinjiang pear are generally longer. There are stone cells in the pulp and cartilage in the endocarp; Seeds dark brown or nearly black. It is widely distributed all over the world. Fruit is edible and has high nutritional and medicinal value.
Conclusion:
Data show that apple trees and pear trees are angiosperms. Apples and pears are the fruits of apple trees and pear trees respectively.
