Abstract:
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.
