After years of research into it, the center came to a conclusion that resistance to flower wilting can sharply be increased even in unfavorable conditions of temperature and humidity when water and ion are allowed to be absorbed into the plant rapidly and its cells' water-keeping capacity is raised.

The center has made the agent to be penetrated into petal tissues with a mixture of sugar, organic acids, microelements, physiological activators, vegetable interphase activators and antiseptics.

According to Ri Pyong Pha, head of the center, the agent makes it possible to keep Kimjongilia in large bloom for a long time and boost its resistant properties. With vegetable interphase activators contained, it also promotes the absorption of organic and inorganic elements into leaves and petal tissues and vivifies the flower.

Applied at the ratio of a hundred parts of water to one of the agent, once a day or a few days when the plant comes into bloom, it lengthens the blooming period a week in summer and 20 days in winter.

It, which produces no adverse effect on the growth of the plant, has already been accepted by greenhouses throughout the country.
