PROCESS FOR PREVENTING PHYSIOLOGICAL INTERFERENCE WITHOUT REDUCE PHOTOSYNTHESIS

摘要

In one embodiment, a method of increasing plant cell resistance to freeze dehydration, comprising applying to at least a portion of a surface of a plant comprising plant cells an effective amount of a finely divided particulate material to increase the solute content of plant cells in the plant, the particulate material comprising at least about 25% by weight of a calcined kaolin, wherein the particulate material as applied permits an exchange of gases on the surface of the plant and the particulate material forms a continuous particulate material film over the portion of the fruit plant surface to which it is applied covering from about 75% to about 100% of the surface. In another embodiment, the present invention relates to a method for preventing sunburn, and other physiological disorders such as watercore, corking and bitterpit, without diminishing photosynthesis, comprising applying to at least a portion of a surface of a plant an effective amount of a finely divided particulate material to prevent sunburn, and other physiological disorders such as watercore, corking and bitterpit, in the plant, wherein the particulate material comprises a heat treated particulate material and the particulate material as applied permits an exchange of gases on the surface of the plant and the particulate material has a thickness from about 1 µm to about 1,000 µm.
