The process of growing avocado flowers.

Avocado flowers include perfect flowers in the sense that in one flower there is a female organ (pistil, which consists of the ovary and ovule) and the male organ (pollen).  In one tree, avocado flowers can reach tens of thousands or even hundreds of thousands of flowers. But those who succeed in becoming fruit are generally in the range of 200-500 only (depending on age and plant conditions). One of the causes is the characteristic of avocado flowers, although it includes perfect flowers but the maturity of female organs and male organs in the same flower is not the same time. Therefore, there is very little chance of self pollination in the same interest. The occurrence of fertilization process is even more through the process of cross pollination: either with other flowers that are still one stalk, or cross pollination with flowers from other stems, or cross pollination from other avocado trees. There are types of avocados that bloom, on the first day when the flowers bloom, in the morning the female organs open, which means they are ready to be fertilized. The opening process only lasts 2-4 hours. After that closes. On the second day, open male organs are ready to fertilize, in the afternoon. At this time the pistil's head has closed, it is no longer possible to be fertilized. This is avocado type A. The other type, on the first day the flowers bloom, the stigma opens in the afternoon or the female organs are ready to be fertilized. While the new male organ opens or is ready to fertilize on the second day, in the morning. This avocado is called type B. Avocado plants with the last type of flower are relatively easier to bear because the time span between the readiness of female organs and male organs is not too far away, and male organs can hold for several hours, before closing. Although it is very possible that the process of pollination is crossed. Because of that, avocado plants with type B flowers, are still relatively easier to produce even though they are planted singly. Although it does not mean that avocado plants with type A cannot produce, it is recommended to plant more than one plant. The unfertilized female organ will close, the pistil head dries, as does the male organ that does not fertilize before the flower finally falls out. Another thing that we must pay attention to, make sure when the avocado plants enter the flowering phase, the plants are enough water (watered) because the flowers become easier to fall if the plants lack water, besides water can compensate for the effects of temperature if the air is too hot. Although avocado plants are vulnerable or unwilling if the conditions are flooded (plants can be stressed or even dead). And one more thing, make sure enough plant nutrients, once the plants enter the flowering phase. Of course, fertilization must be adjusted to the needs of the generative phase (production phase), not by fertilizing to spur growth when the plants are still vegetative phase (growth phase).
