下列植物生理的理论研究成果，是生物化学调控技术的依据。 (一)植物根茎叶的表面可以吸收具有生理活性的有机物质。这些物质一进入植物体内就可随维管束的筛管液流与导筛水流传布周身。植物的这种特性给农用药剂大开方便之门。原来需要从根系吸收的矿质元素中，有些元素易被土壤固定，因而不容易被植物吸收利用，若采用溶液喷射的根外追服，就能解决这个问题。此外，农用药剂可以“内服”——注射法，并能在体内转移与保留。一向“外敷”用作保护层的除害药剂，只能对覆盖的枝条有效，用量大，期限短。二者比较起来，已不可同日而语。 (二)溶液培养植物成功，确定了营养代谢所需的水分与必需的矿质元素的性质和数量，成为合理、定量灌溉与施肥的依据，并给无土栽培作出了榜样。自然资源在太阳的操纵下，不仅供给植物生活的能量，还给植物个体发育提供必需的生态环境。再通过植物体内部的相互影响，植物的遗传性状才能实现。植物为了维持生存，依靠感应来适应气候中光、温和季节周期的变化，以及逆境的胁迫。植物常在敏感部位受到刺激后，便发出信使在体内传递，影响效应部位反应出来。研究发现，这些信使是激素一类的生物化学物质，它们的生理活性强，功能各异，化学结构比较简单，可以人工模拟与批量合成。无论是内原激素，还是人工调节剂，在植物上微量施用，就会启发显著的生理变化。 “自然资源在太阳的操纵下”指的是（ ） 水分、矿质元素在日照下产生能量，造成特定环境。植物从日照中获得能量和必需的生态环境。 气候中，光、温和季节周期性的变化。日照对植物实现遗传性状所具有的决定性的作用。A.水分、矿质元素在日照下产生能量，造成特定环境。B.植物从日照中获得能量和必需的生态环境。 C.气候中，光、温和季节周期性的变化。D.日照对植物实现遗传性状所具有的决定性的作用。
