2 results about "Drought stress" patented technology

The present invention relates to a method and container for the cultivation of ornamental plants, facilitating the application of the method of drought stress to reduce cell elongation of plants grown in a slowly absorbing material such as peat moss without the use of chemical retarding agents. The invention thus discloses a container for the cultivation of plants comprising a layered structure incorporating a rapidly liquid absorbing reservoir and a body of suitable cultivation substrate. According to an advantageous embodiment a layer is furthermore inserted between said reservoir and said cultivation substrate in order to obtain a controlled flow of liquid from said reservoir to said cultivation substrate.

The invention provides a research method for increasing the oxidation resistance of Ilex verticillata. The method includes: selecting the biennial cuttage seedlings of two Ilex verticillata varieties,and performing acclimation in a greenhouse for 2 months; selecting 18 cuttage seedlings of each of the two varieties, separating each variety into two groups, spraying melatonin to one group, and spraying equal-amount clean water to the other group; performing identical drought stress treatment at the same time; collecting fresh leaves immediately after the treatment, on the seventh day after thetreatment and on the thirtieth day after the treatment, quickly freezing the collected leaves in liquid nitrogen, and preserving the frozen leaves in refrigerator of ultralow temperature of minus 80DEG C; measuring superoxide dismutase and peroxidase activity and malondialdehyde content. The research method has the advantages that by applying external melatonin to perform treatment, the influence of the melatonin on the oxidation resistance of the Ilex verticillata cuttage seedlings under drought stress is comparatively analyzed; the research results can lay a foundation for the research ofthe Ilex verticillata physiological mechanism responding to the drought stress and measures for increasing the drought resistance of the Ilex verticillata and the popularization of the Ilex verticillata in drought regions.
