摘要/Abstract

摘要： 1992年9月至199年6月间,对分布于山西娘子关泉的胶串珠藻(Batrachospermum gelatinosum)生长和分布的季节动态进行了研究.定期测定水温、pH值、流速、藻体出现频度、平均盖度和藻体的一些形态特征.结果表明,娘子关泉域水体温度、水体的pH值和流速季节变化幅度都不大;藻体出现频度和盖度有明显的季节性变化,从秋季到次年的春季逐渐增加,生长最旺盛的时期在5月;藻体生长发育有明显的季节性变化规律,在晚秋到早夏生长良好,在春末夏初生长达到高峰,而且藻体各部分的生长和发育基本上同步.

Abstract: This paper studied the seasonal dynamics of the growth and distribution of freshwater rhodophyte Batrachospermum gelatinosum in Niangziguan of Pingding County,Shanxi Province,North China,from September 1992 to June 1994.The water temperature,pH,current velocity,occurrence frequency,mean cover,plant height,whorl diameter,fascicle length,carpogonial branch length,carpogonium length,carpogonial diameter,carposporophyte number per whorl,carposporophyte diameter,carposporangium length and carposporangium diameter were examined regularly.The results showed that water temperature was the maximum in July and minimum in January,water pH had little change,and the variation of current velocity was irregular.The occurrence frequency and mean cover of the alga were increased from Autumn to Spring,and the highest were in May.The seasonal growth dynamics of this alga were evident.It developed well from late Autumn to early Summer,and peaked in May.It was positively correlated to each other among morphological characteristics,and the development was synchronal in all parts of the plant.
