Resistance of Tea Plants to Blister Blight in Soils augmented with Nickel

IN 1961, protective spraying of tea plants with nickel chloride hexahydrate gave dramatic control of the blister blight disease1, and later certain salts of nickel were shown to possess eradicative control properties when applied in a dilute aqueous solution to tea foliage 3–5 days after inoculation with Exobasidium vexans Massee, the causal pathogen2. Very recently it has been observed that, in soils augmented with nickel ammonium sulphate and nickel nitrate, tea plants developed disease resistance.

The Method of Selection of the Cold Resistant Tea Plant (Part 1)

The fact that cold resistance of tea plant was very low At its young stage was well demonstrated by the tests of osmotic pressure, plasmolytic permeability and hydrophilic colloid.In the early growth stage, the relation between cold resistance and osmotic pressure was insignificant. The growth seemed to have some effect on cold resistance. It could be considered that the variation of cold resistance caused by other factors as above mentioned was the main cause of ineffectiveness of early individual selection.
