铁(Fe2+)对红地球葡萄试管苗生长发育的影响

Effects of ferrum (Fe2+) on Growth and development of red globe grape were investigated in this paper. The results showed that rooting period was shortened, but budding period was prolonged，root/shoot ratio and chlorophyll content was enhanced with the increase of Fe2+ concentration; plant height, node number, leaf number and shoot fresh and dry weight were all up to the highest quantity when Fe2+ concentration was 13.9 mg/L; root vigor rose with increase of Fe2+ concentration when Fe2+ concentration was under 13.9 mg/L, but weakened with increase of Fe2+ concentration when Fe2+ concentration was over 13.9 mg/L.
