Abstract
Specialized epidermal trichomes on the leaves of the epiphyte, Tillandsia paucifolia (Bromeliaceae) accumulate amino acids from solution. Simultaneous net uptake of 17 amino acids was determined using high performance liquid chromatography. Uptake occurs against concentration gradients at least as high as 10(4).
摘要
附生植物薄叶凤梨（凤梨科）叶片上的特化表皮毛能够从溶液中积累氨基酸。采用高效液相色谱法测定了同时净吸收 17 种氨基酸的情况。吸收至少在高达 10（4）的浓度梯度下发生。
