Potatoes – tasty and useful product which is constantly eaten practically by each family. He does not demand special conditions of storage, however root crops need to be protected from sunlight to avoid pozeleneniye.
The reason of emergence of greens on the ripened tubers – the chemical reactions happening in potato under the influence of sunlight. The fact is that under peel the chlorophyll which in the presence of the corresponding conditions begins to interact with ultra-violet and infrared radiation contains, – well-known reaction of photosynthesis is so started.
The chlorophyll contains in one and all plants. Under the influence of light it gives them characteristic green color, however sometimes paints leaves in violet shades. Potatoes tubers initially not green only because are in the earth and are reliably protected from sunshine. By the way, at artificial lighting the process of photosynthesis is not started therefore if root crops have gained uncharacteristic color for them, so in the subfield there are slots.
As potatoes belong to plants of family of nightshade family, contain in it solanin – the strongest poison. During photosynthesis process its contents increases several times. By the way, substance is present also at mature tubers, but at insignificant doses – at concentration no more than 0.05%. And here in foliage, boxes fruits and the become green root crops its level considerably increases. The become green potatoes are not suitable in food as the contents corned beef raises in the whole root crop, and not just its certain part. In large numbers substance is toxic and at the use of 250-400 milligrams is capable to lead to lethal outcome. In terms of concentration of toxic agent sprouts are considered as the most dangerous. However the become green potatoes can be used as seedling material – at this time in root crop the reactions positively affecting the speed of cultivation of harvest are started.
