When we talk about orange tree or citrus sinensis, Valencia comes to our mind, since orange is the fruit that identifies this area of the Mediterranean. In this region it is very common to purchase citrus sinensis for cultivate and sell oranges.
Citrus sinensis is not a large tree. In Viveros Valero e Hijos, when we sell an orange tree, you will know its dimensions and how is it going to develop. The orange tree leaf is perennial, although it has not a determined fixed form, because we can find round, pyramidal and oval leaves, from 7-10 cm.
The Citrus aurantium or Citrus sinensis has white and very fragrant flowers, called “orange blossom”, born singly or in bunches. During the blooming time of the year, orange trees are beautiful and the fields change colours. The big problem for orange trees is the frost weather, because neither the tree nor the fruit are resistant to the cold.
Orange is not just a great dessert delicacy, but its juice is also used to make cocktails with or without alcohol.
Furthermore, it is important to know that orange or citrus sinensis may suffer parthenocarpy, that is the fruit development without sustainable seeds. This usually happens due to the plant careless, especially on the issue of pollination and fertilization, but it can also be caused by postzygotic incompatibility. Usually, the problem relies on the lack of the tree crown irrigation. This means that the fruit does not finish absorbing all the water it needs for a perfect development. In any case, if you have any questions on parthenocarpy, you can ask at Viveros Valero e Hijos about it, since we are a nursery specialized and expert in citrus sinensis.
