    STRUKTUR ANATOMI PERBANDINGAN AKAR BIBIT KELAPA SAWIT (Elaeis Guineensis Jacq.) DENGAN CEKAMAN PENGGENANGAN DI LAHAN GAMBUT DAN TANPA CEKAMAN PENGGENANGAN

    The palm oil plant (Elaeis guineensis Jacq.) has survival in flooding conditions on peatlands. However, the connection between oil palm resistance and responses to the anatomical structure of the root was still unknown. Changes in root anatomy under flooding conditions can be observed by comparing the root anatomical structure which experienced flooding stress to root tissue structures that do not experience flooding stress. The purpose of this research was to observe the comparison of the root anatomical structure of oil palm which experienced flooding stress on peatlands and without flooding stress. Samples of the palm oil plant roots were treated with flooding experience for 30, 50, 70 and 90 days. Root anatomical preparations used paraffin method. The results showed that the root anatomical structure of the palm oil plant seedlings consisted of epidermal, hypodermal, sclerenchyma, cortex, endodermis, and stele tissue, in which there were vascular bundles and pith. Anatomical structure of the roots of palm oil plant seedlings showed that experience flooding in peatlands could not be observed, because the anatomical conditions of the roots were shrinking and the root cortex tissue was damaged, which were caused by the delay in fixation of the root samples after dismantling the palm oil plant seedlings, so that the samples underwent dehydration or dryness.
