在微量元素过量或不足的土壤中生长的植物,可能发生广泛的解剖学异常。缺硼(图一)锰、锌或铜的植物中的显著的解剖学变化已有报道(Warington,1926;Eltinge,1936;Reed and Dufrenoy,1942)。Eltinge(1941)研究了锰缺乏对番茄(Lycopersicumesculentum)解剖结构的影响。在缺锰植株叶的栅栏细胞中只有很少的正常质体能够被找到。大多数质体空泡化,或形成轮廓模糊不清的颗粒状物。锰缺乏病的后期,质体消失,在细胞质产生一种黄绿色溶液。
A wide range of anatomical abnormalities may occur in plants that grow in the soil with excess or deficiency of trace elements. Significant anatomical changes in boron-deficient (Figure 1) manganese, zinc or copper plants have been reported (Warington, 1926; Eltinge, 1936; Reed and Dufrenoy, 1942). Eltinge (1941) studied the effect of manganese deficiency on the anatomy of Lycopersicum sculentum. Only few normal plastids can be found in palisade cells of manganese-deficient plants. Most plastids vacuolize, or form obscured particles. Late plagues of manganese deficiency plastids disappeared, producing a yellow-green solution in the cytoplasm.
