Abstract
Polygonatum odoratum ‘Veriegatum’,
commonly known as Soloman’s Seal, is a
liliaceae perennial plant and is produced as
cut leaves in Taiwan. The influences of
irradiance, CO2 concentration, and air
temperature were studied on leaf net
photosynthetic rate of Polygonatum
odoratum. At 350 ppm CO2 concentration,
leaf net photosynthetic rate was saturated at
irradiance above 350 μ mol m-2 s-1
photosynthetically active radiation (PAR).
Leaf net photosynthetic rate increased as
temperature increased from 13 to 25℃ and
declined with increasing temperature from
25 to 38℃.The low temperatures for the
sprouting and elongation of the shoot range
from –1.5 to 5℃, while chilling at 2℃ for
59 days of storage resulted in earliest
sprouting in 8 days, when transferred to
15-20 ℃ . A significant linear correlation
(P<0.001) between the rate of sprouting
which was determined by both the
temperature and storage time and the
thermal time of cold treatment was observed,
and could be used for the off-season crop
prodution.
