摘要

Phyllody is a mycoplasmal plant disease characterized by extreme dwarfing of the plant or plant parts coupled with very short internodes, flattening of stem covered with mass of highly reduced leaves and very often flowers, provided the flowering is terminal. A high frequency occurrence of phytoplasmal phyllody in seed crop of cabbage and a low frequency occurrence in palak [Beta vulgaris] were recorded in the cold arid desert of Leh in Ladakh, Jammu and Kashmir, India. Inflorescence of both crops showed typical symptoms of flattening, shortening of internodes and rapid reduction in leaf size towards the tip of the head and the flowers at the tip of the head were highly reduced, twisted and non-fertile. Flowers were totally absent in the internodal regions though this appeared in healthy heads. The incidence was 20.8 and 1.2% in cabbage and palak, respectively. Both cabbage and palak phyllody were observed from adjacent fields. The observed frequency of cabbage phyllody is far higher than what was reported from European countries.
