Effects of calcium-containing natural fertilizer on Camellia sinensis (L.) Kuntze

The effects of application calcium-containing natural fertilizer on the functional state tea plant were studied. Application calcium resulted weakening negative high temperatures and water deficiency due to an increase in its heat resistance (on average by 30 - 40%), catalase activity 5 10 %), as well adaptive rearrangement pigment ratio increasing content carotenoids, chlorophylls their activity. In general, more efficient functioning signaling intracellular network provided better adaptability plants extreme conditions recovery after subsequent rehydration, which a whole contributed shoot growth 20%) yield 27 33%.
