Fibres from different structural parts of the coconut palm tree (Cocos nucifera, linn.) have been examined for properties such as size, density, electrical resistivity, ultimate tensile strength,...

Aug 1, 2010 · The coconut inflorescence is composed of numerous rachillae arranged spirally on the main rachis (Fig. 2 D). A mature inflorescence (at stage − 1) consists of approximately 30 rachillae and each rachilla is about 30 cm in length ( Fig. 2 E).

Palm leaves are generally of three types. Pinnate or feather-like leaves have leaflets entirely separated from each other and are attached perpendicularly to the rachis, an extension of the petiole into the leaf blade (Figure 6). An example of a pinnate-leaved palm is the coconut palm.

Pestalotiopsis palmarum is the causative agent of a fungal disease of bananas, coconut and Date palms. The fungus causes leaf spots, petiole/rachis blights and sometimes bud rot of palms. Unlike other leaf spot and blight diseases, Pestalotiopsis palmarun attacks all parts of the leaf from the base to the tip. Whereas most diseases only infect ...

The crown of the coconut palm consists of its fronds, flowers, and fruits, and is usually between 8-9 m (26-30ft) in diameter with fronds evenly distributed around the stem. Fronds of the coconut palm are pinnate, with a primary rachis. The rachis has 200-250 lanceolate leaflets on each of the two horizontal planes.

In field-grown coconut palms symptoms usually start on older fronds progressing to younger fronds. Symptoms including discoloration of internal tissue, profuse pathogen sporulation, fruiting body formation, and death of entire fronds, universally characterize rachis …

In field-grown coconut palms, symptoms usually start on older fronds, progressing to younger fronds. Symptoms including discoloration of internal tissue, profuse pathogen sporulation, fruiting body formation, and death of entire fronds universally characterize rachis blight caused by …
