[Study on main inheritable parameters of test-tube plants population of Bupleurum chinense in different growing...

To determining the growth status and medicine quality of test-tube plants of Bupleurum chinense.

Measuring the field characters of the labeled plants at fixed period after turning green,such as plant height, number of tiller, number of leaves. Using statistical methods to analyse the measured data

Each genetic characters standard deviation and relative standard deviation are all smaller at vegetative growth phase, bud forming phase and seed ripening phase. The test-tube plants population of Bupleurum chinense grows consistently. Its uniformity is higher, variability is low. Bupleurum chinense length and weight of root relative standard deviation are all low. The average root length and weight are more predominant than ordinary seed plants. The roots have high content of effective components. Bupleurum chinense population pharmaceutical character is excellent. The medicinal quality is consistent. The number of branch stem and effective fruit bunch is bigger, The seed production is higher. The aerial part yield is large, The economic value of test-tube plants of Bupleurum chinense is higher. The correlation between each characters of test-tube plants of Bupleurum chinense is different from the ordinary seed plants in different growing periods.

The botanical and pharmacognostic characters of test-tube plants of Bupleurum chinense are excellent.
