Eggplant (Solanum melongena L. var. esculentum 'Burpee's Black Beauty') and soybean [Glycine max (L.) Merr. 'Wells II'] seedlings were assigned to a greenhouse or a windless or windy outdoor environment. Plants within each environment received either periodic seismic (shaking) or thigmic (flexing or rubbing) treatment, or were left undisturbed. Productivity (dry weight) and dimensional (leaf area and stem length) growth parameters generally were reduced more by mechanical stress in the greenhouse (soybean) or outdoor-windless environment (eggplant) than in the outdoor windy environment. Outdoor exposure enhanced both stem and leaf specific weights, whereas mechanical stress enhanced only leaf specific weight. Although both forms of controlled mechanical stress tended to reduce node and internode diameters of soybean, outdoor exposure increased stem diameter.
茄子（茄属龙葵变种‘伯比黑美人’）和大豆（大豆属‘威尔斯二号’）幼苗被放置在温室、无风或有风的室外环境中。每个环境中的植株接受周期性地震（摇晃）或触觉（弯曲或摩擦）处理，或不做处理。生产力（干重）以及尺寸（叶面积和茎长）生长参数通常在温室（大豆）或室外无风环境（茄子）中受到机械应力的影响比在室外有风环境中更大。室外暴露增加了茎和叶的比重，而机械应力仅增加了叶的比重。虽然两种形式的可控机械应力都倾向于减小大豆的节和节间直径，但室外暴露增加了茎直径。
