Compared with the major crops and forages in China, its nutritional value was evaluated. The contents of crude protein and total amino acid in leaves of P. microphylla were 134.8 and 108.1 mg/g respectively. It was rich in contents of Vc (3.6 mg/g), βcarotene (0.2 mg/g) and mineral elements. So this species is a wild plant resources which can be utilized widely.展开更多

St. Hil.can occur from both leaf and leafstalk by tissue culture, and then differentiate to young plants in the proper medium. The optimum medium for the inducing of callus and the differentiation of buds is MS+1.0 mg·L-1 6-BA+0.2 mg·L-1 NAA+30 g·L-1 sucrose+0.8% agar. The optimum medium for rooting is 1/2MS+0.2 mg·L-1 NAA+30 g·L-1 sucrose+0.8% agar. The survival rate of transplanting reaches above 95%.展开更多
