Boron deficiency symptoms

In the absence of boron, crops cannot form or form abnormal floral organs, pollen tube formation is difficult, fertilization is impeded, and pollen grains are poorly developed, resulting in "flower but not real", "actually not fruitful", "fruitful and undesirable" and so on. . Grape "size fruit", "paste fruit", apple "fruit shrinking", and falling fruit fruit, fruit set rate, malformed fruit, etc., are directly or indirectly due to lack of boron.

Citrus: Boron deficiency is susceptible to yellow leaf blight, tipped shoots, old leaves become thick and brittle, veins become thicker and corked, skin burst, tree vigor is weak, fruit set thin, fruit juice capsule shrinks, residue is juicy Less, tan-colored plastic spots, when the pulp disappears, the skin thickens, shrinks, and the fruit is as hard as a stone.

Chestnut: Necrosis of boron-deficient growth points, sprouting of lateral buds, formation of arbuscular branches, poor pollination and fertilization, or malnutrition after pollination and fertilization, resulting in embryo abortion or developmental stasis and the formation of puffy and real empty pupae.

Grapes: In the absence of boron, the leaves have pale yellow spots, poor growth of shoots, coarse internodes of stalks, poor berry development, different sizes of ears, and often detached red-brown corollas. There are many unfertilized seedless kernels in fruit bunches. Small fruit, the formation of the size of the fruit, filling the fruit, the phenomenon of 'family and grandchildren'.

Boron deficiency can lead to poor fruit development and malformation of the pear tree. The fruit surface is uneven and the surface of the skin has watery, necrotic areas. Afterwards, it becomes hard brown, the skin cracks, shrinks, and there are scattered cork or stone cells in the pulp. fester. The lack of boron in the peach tree produces brown pegs near the nucleus of the fruit and often breaks along the suture. The symptoms of boron deficiency in fruit trees occur first and are reflected in the growth point and new leaves.
