硼元素是植物生长发育的微量元素之一,它以被动吸收的方式进入植物体,能和P和OH基形成络合物。硼与糖结合,使糖具有极性,通过质膜,促进糖运输,与糖形成络合物.在核酸代谢中具有重要作用,硼加强花粉的发芽和花粉管的伸长,柱头和花粉中积累足够的硼有利于受精作用,硼在细胞壁中含量高时,能提高植物的抗性,并提高原生质粘性,增加胶体结合水的能力.硼还能提高番茄、黄瓜果实中维生素C和糖的含量,促进植株对磷素的吸收。蔬菜作物在田间栽培条件下,表现出硼的丰缺程
Boron is one of the trace elements of plant growth and development. It enters the plant by passive absorption and forms a complex with P and OH groups. Boron and sugar combine to make sugar polar, pass through the plasma membrane, promote sugar transport, form complexes with sugars, play an important role in nucleic acid metabolism, boron enhances germination of pollen and elongation of pollen tubes, and in stigma and pollen Accumulation of sufficient boron is beneficial for fertilization, and boron can increase plant resistance and increase the viscosity of protoplasm and increase the ability of colloid to bind water when it is high in the cell wall. Boron can also increase the content of vitamin C and sugar in tomato and cucumber fruits Content, to promote plant absorption of phosphorus. Vegetable crops in the field cultivation conditions, showing the abundance of boron deficiency process
