摘要: Quadratic relationship between the age of a tea leaf and net photosynthetic rate (PN) has been found. A progressive increase in PN was recorded for four months. Then slowly declined, yet even seven-month-old leaves sustained low PN. In shoot, increased from first onwards. Besides physiological maturity proximity, photon flux density (PFD) played an important role reducing The influenced by cultivation procedures which turn disrupted quantum PFD transmitted through canopy.
