The major mechanism of formation of the ophiolites and the podiform chromite diposits in the Western Zhungeer area includes partial melting of the primary pyrolite and differentiation of the melt-out materials after they intruded. The differences between the two ophiolite types are related to the degree of partial melting of the pyrolite and depth of formation of magma chambers as well as oxidation state of the magmas.

Results:(1) The conchosporangia of brown yellow mutant was smaller and mature time was 15 days later than the parents. Thallus grew slowly in early stage, but average daily growth rate reached (7.50±1.18) cm after blade length was over 60 cm.(2)The emerald conchocelis were easy to mature and had special developmental mode that the spherulocytes can directly develop into sporangial branchlets and conchosporangia without thick conchocelis stage. Emerald blades were low in RPE with just (6.4710±0.0184) mg/g dry mass. The thallus grew quickly, average daily growth rate reached (11.95±2.33) cm after blade length was over 60 cm.(3) The conchocelis filaments of breen mutant were thin and short. Thallus grew slowly and had low contents of three phycobiliprotenin and chlorophyl.
实验进行50d。结果:(1)褐黄色突变体藻蓝蛋白和别藻蓝蛋白含量低;孢子囊枝的细胞较小,且大量形成时间比亲本晚15d;幼苗培养初期日平均生长量仅为(1.22±0.28)cm,当叶片长到60cm左右时生长优势逐步凸显,日平均生长量可达(7.50±1.18)cm;(2)翠绿色丝状体容易成熟,发育方式特殊,营养藻丝不经过藻丝加粗阶段,直接由球形细胞发育成孢子囊枝和壳孢子囊;翠绿色叶状体藻红蛋白含量低,仅有(5.5130±1.0496)mg/g;叶状体生长快速,60cm长的藻体日平均生长量高达(11.95±2.33)cm;(3)褐绿色突变体藻蓝蛋白、别藻蓝蛋白和藻红蛋白这3种色素蛋白和叶绿素的含量均较低;藻丝细胞短且细,叶状体生长速度较慢。
