slightly increasing stage was also called seeding period (0 d¡«75 d); the bud stage was 76 d¡«84 d, flower stage was 85 d¡«95 d and the 20 days was called the rapid growth period; the slow growing period was defoliation period (96d¡«125d).The trend of chlorophyll a, b and total content was the same, it was the highest at flower period, and then was decreased; the decline of the soluble protein content was earlier than that of chlorophyll content. Hill reaction, Ca2 +-ATPase and Mg2+-ATPase activities were single-peaked curve, they were the highest at the bud stage; The curve of diurnal variation of leaf photosynthesis showed two single peak at seeding period, but it was single-peaked curve at other periods. The daily change of stomatal conductance was accorded with that of transpiration rate. You harvest leaf and shoot before flower stage, but you do seed after defoliation period. Promoting measures must be used before the quickly increasing stage.

As was observed both specimens "a" and "b",
chlorophyll content increased with photosynthesis and peaked during flowering
  before going on a gradual decline, but not before that of soluble proteins

The Hlll reaction, as well as Ca2 +-ATPase and Mg2+-ATPase activities
  all peaked just before blooming began

Photosynthesis rate peaked twice during germination,
  which was once more than in any other stage of the plant's growth

Strong positive correlation was observed
  between Stomatal conductance and transpiration rate

For maximum yield of seed or stem, harvesting should take place
  either before flowers bloom or after leaves fall

All growth-spurring measures must be implemented before growth rate
  reaches a zenith or risk not being effective

Keywords:
  00 d¡«75 d   = germination
  76 d¡«95 d   = period of accelerating growth
    76 d¡«84 d = flower budding [×¢Òâ: ͼÏÔʾ flowering = budding+blooming ºÍÏÂÃæÔ­ÕªÒª¶¨Ò岻ͬ]
    85 d¡«95 d = blooming [¿ª»¨]    [full bloom = Ê¢¿ªÅ­·Å]
  96 d¡«125 d = period of decelerating growth, aka, "tequisous"  or  [¸üÇ¡µ±] "senescience"  [¿´Í¼]
