Anatomy And Ultrastructure

Taro, Colocasia esculenta (L.) Schott (Araceae) is a monocot grown as a starchy root crop in much of the tropics and subtropics. It is subject to a number of fungal, bacterial, and viral diseases. Viral diseases have inhibited the cultivation of taro in parts of New Guinea and the Solomon Islands where taro is an integral part of the culture. Two different viruses, a Rhabdovirus, the Large Bacilliform Particle (LBP), and a smaller bacilliform virus, are the cause. Dasheen Mosaic Virus, a Potyvirus, has been found wherever taro is cultivated and produces a leaf mottle but is not lethal to plants.Colocasia esculenta cv K268 corms, infected with virus, were obtained from Michael Pearson, Department of Botany, University of Papua New Guinea, Port Moresby, New Guinea. Upon planting some of the corms produced leaves with virus symptoms. Others were symptomless but symptoms could be induced by stress.

The Creation

Taro (Colocasia esculenta) is an essential crop in Papua New Guinea, especially in the highlands where taro grows at high altitudes (above 2,000 m) and sweet potato is absent. Taro and its cultivation are part of the collective memory of the Oksapmin society, in Sandaun province. The creation, maintenance, and harvest of a taro garden follow elaborate techniques and rules, the knowledge of which is not universal among villagers. This article describes the making of a taro garden by Oksapmin cultivators. The process is divided into two parts: activities related to the “mother garden”, where cuttings for the garden-to-be must be harvested, along with activities and techniques involved in preparing the new taro garden. The author discusses the significance of taro gardens in Oksapmin society.
