Sci-Tech Chinese Scientists Develop Substance to Prolong Life of Flowers

¡¡ Chinese scientists have developed a substance which can prolong the life of flowers.

¡¡ Researchers at Heilongjiang Academy of Science in northeast China said the effectiveness of the substance is equivalent to the same product on the international market, but it is a lot cheaper than its international counterpart.

¡¡ "The gelatinous substance has high purity and low toxicity and it can also prevent flowers from being harmed by pests," said Liu Yuguang, one of the researchers at the Academy.

¡¡ Liu explains that the substance prolongs the life of flowers by releasing nutrients to flowers. Water and earth cultivation often make the flowers wither because of a shortage of nutrients or too much of them.

¡¡ Liu also says the amount of nutrients put into the substance can be delayed or advanced to control the flower blooming process.
