استخدام طرق ترشيحية للكشف عن الفايتوبلازما و تحديد انتشارها في بعض المحاصيل و نباتات الأدغال-الأعشاب في المنطقة الوسطى من العراق

Abstract EN

This study was conducted to evaluate the cfilcacy of several histological methods for the detection and monitoring the multiplication of phytoplasma in infected plants.

Results obtained showed that electron microscopy was the most efficient and direct method.

Other methods such as, Dicnc's stain with light microscopy and DAPI stain with fluorescence microscopy, were found to be efficient.

These methods made the detection of the phytoplasma in infected plants possible by using limited facilities.

Phytoplasmas were detected in more than 25 spccics belonging to 17 plant families collectcd from locations in Baghdad, Diahla and Babylon.

The highest incidence (82%) was in Suaeda plants showing witches' broom symptoms followed by 30.5-32% in sesame plants and 25% in tomatoes.
