The identification method of male and female saplings of soft jujube kiwifruit tree is as follows:
1. Observe the dorsal side of the leaf and the reticular veins.
The back of the leaves of the mother sapling is dark grayish-white, and the fine hairs are numerous and dense, and even the reticulated veins are covered with fine hairs. The back of the male sapling leaves is greenish-grayish-white, with sparse fine hairs, obvious reticular veins, and clear green.
The reticular veins of the mother sapling are parallel and regular, while the male sapling is irregular. The leaves of the mother tree have better gloss and are smoother to the touch, while the leaves of the male sapling are rougher and have a poor feel.
2. Observe the bud eyes.
The bud eyes of male saplings of soft jujube kiwifruit are basically protruding outward, while the bud eyes of female saplings are concave inward, which is more obvious in the dormant period of the plant.
3. Observe bud spacing and tree shape.
After entering the growth period, the bud spacing of male saplings is relatively narrow, the leaves are small and thick, the leaf color is darker, the shape is rounder, and the tree shape looks more compact. The mother sapling, on the other hand, has a wide bud spacing, large, thin leaves, light leaf color, pointed leaf shape, and a loose tree shape. There is a difference between the male tree and the mother tree in the overall shape of the plant, the tree shape is very compact, the pruning is very rough is generally the male tree, on the contrary, the tree shape is very loose, the pruning is very regular is generally the mother tree.
Fourth, observe the stem.
The stem nodes of the mother saplings are thin and long, and the petioles are also relatively long. The node spacing of the male saplings of soft jujube kiwifruit is thicker and shorter.
5. Identification of stamens.
Male flowers do not have stigmas, and pistils have stigmas. This method is also suitable for identifying male and female seedlings.
Through the above steps, the male and female saplings of the soft jujube kiwifruit tree can be identified more accurately.
