EFFECT OF Ca, P, Mg, Fe ON THE GROWTH OF NOSTOC FLEAGELLIFORMER

本文报道了在发莱产区.利用自然的光温条件,控制C_a、P、F_(?)、M_g等营养素培养发莱的试验.试验结果表明在发莱生长的旺季,在自制的半开放式培养箱内,径29天的培养,在不同浓度梯度的C_a、P、F_e、M_g等培养基中、发莱丝体的生长量有显著的差异。

This paper presents the effect of four elements (C_e. P.F_e.M_g) on the growth of Nostoc fleagelli-former The culitivating test were making under nature light and temperature But contents of Ca, P, Fe, Mg four elements were strictly controled when the four contents of elements in cultivation were ca 49ug/ml, p 13ug/ml Fe 0.008ug/ml, Mg 0.099ug/ml nostoc fleagelliformer were growing better
