Abstract:
American ginseng （Panax quinquefolium) was taken as a test material,and five gradients of temperature （T) ranging from 6 ℃ to 18 ℃ were set up to rear its seedlings to determine impacts of temperature on growth and development of the medicinal plant.Agronomic characters such as emergence rate of germinating seeds,height of seedlings on the date of leaf expansion,and developmental duration （N) of seedlings from seed germination to leaf expansion were observed and measured,and data were subject to an ANOVA.The results indicated that T ranging from 6 ℃ to 12 ℃ was favorable to emergence of the seeds but significantly inhibited height of the seedlings,whereas that ranging from 15 ℃ to 18 ℃ caused emergence rate to decrease to some extent but promoted seedlings to grew into a normal height.The threshold temperature （C) was calculated 3.7 ℃ in its early seedling stage,and the thermal constant （K) was 272.1 ℃?d.Variable N was inversely proportional to T,and a new reciprocal model between them was established then,N=K/（T-C)=（272.1±22.9)/[T-（3.7±0.8)].The 2 parameters reflect thermal quantities needed by the plant for development in the stage,which contributed to explain temperature effects,and optimize both techniques of accelerating seed germination and cultivation for the medicinal plant.
