Abstract

Shoot biomass production, alkaloid content and composition as influence by cadmium, manganese, nickel and lead at uniform dose of 5 mM were investigated in Catharanthus roseus plants grown in sand culture. Treatment with Mn, Ni, and Pb significantly enhanced total root alkaloid accumulation. Cd and Ni treatment resulted in two-fold where as Pb treatment resulted in three fold increase in serpentine content of roots. The non-significant affect on biomass suggests that plants can withstand metal stress at the level tested with positive affect on root alkaloid content.

摘要

在砂培条件下生长的长春花植株中,研究了在5 mM均匀剂量的镉、锰、镍和铅影响下的地上部生物量生产、生物碱含量及组成。锰、镍和铅处理显著提高了总根生物碱积累量。镉和镍处理使根中蛇根碱含量增加了两倍,而铅处理使其增加了三倍。对生物量无显著影响表明,在所测试水平的金属胁迫下,植株能够耐受,且对根生物碱含量有积极影响。
