Aims We investigated aerenchyma formation in stems of riparian plants Arundinella anomala and Salix variegate as affected by addition of ethylene and a-naphthalene acetic acid under non-flooded conditions in order to ascertain whether phytohormone ethylene and auxin are direct stimuli for aerenchyma formation in flooded plants.

为了探究乙烯和α-萘乙酸是否是水淹环境条件下植物体内通气组织形成的直接原因，对三峡库区岸生植物野古草和秋华柳在无水淹环境条件下施加乙烯利和α-NAA后茎中通气组织的形成情况进行了研究。

Plant height, leafstalk length, leaf length, leaf width and leaf thickness of water hyacinth did not vary significantly at the range of pH 3.5 to 9.0, while root length, stolon length and root vigor declined obviously with the increasing pH.

随营养液pH值升高，水葫芦的相对生长率从6.12倍降到3.08倍。pH值在3.5—9.0之间，水葫芦株高，叶柄长度，叶片的长度、宽度和厚度在不同酸度条件下无显著差异，根长、茎长和根系活力随pH升高明显下降。

The muskmelon vigorously grew at potassium level of 240 mg/L in nutrient solution, which was beneficial to macroelement absorption. However, no significant difference in leaves area and fruit weight were recorded among the three treatments.

试验结果表明：营养液中240 mg/L的钾素水平可增强网纹甜瓜植株的生长势，促进茎杆粗壮，有利于矿质元素吸收，但对叶面积无显著影响。
