A study of the growth of the maritime halophyte Aster tripolium L. has been carried out over a range of salinity treatments. The regression approach to growth analysis using frequent small harvests has been used to allow 'continuous' measurement of growth over a period of 36 d. Salinity was applied with the major ions present in ratios typical of those found in seawater. Growth was inhibited in terms of both dry weight production and leaf expansion at salinity levels equivalent to 0.625 strength sea water (full culture solution 300) and above, with the greatest effect being seen in terms of leaf area. Aster tripolium did not show increased succulence at high salinity, leaf fresh weight to dry weight ratio in fact declined, whilst leaf fresh weight per unit area remained constant. It should be noted that the plants exhibit low growth rates due to the low light intensity used.
对海生盐生植物滨海紫菀（Aster tripolium L.）在一系列盐度处理条件下的生长情况进行了研究。采用频繁小样本收获的回归方法进行生长分析，以便在36天的时间内“连续”测量生长情况。盐度处理中主要离子的比例采用海水中典型的比例。在相当于0.625强度海水（完全培养液300）及以上的盐度水平下，滨海紫菀的干重产量和叶片扩展均受到抑制，其中对叶面积的影响最大。滨海紫菀在高盐度下并未表现出肉质化增加，事实上叶鲜重与干重之比下降，而单位面积叶鲜重保持不变。应当指出的是，由于光照强度较低，这些植物的生长速率较低。
