Abstract
Potato plants grown from true seed were naturally infected with the Solanum apical leaf curling virus (SALCV) at the high jungle site near San Ramon, Peru. Tubers from these plants were greenhouse indexed. Symptoms of SALCV infected potato plants include apical rolling, stunting, delayed emergence, weak plants, hair sprouts, and tuber dormancy. These symptoms superficially resemble certain aspects of unusually severe current season potato leafroll virus (4) infection or those of the aster yellows and stolbur mycoplasma diseases (5). Up to 12 percent of the indexed plants were naturally infected with SALCV and SALCV was demonstrated in approximately half of the tubers that produced hair sprouts.
Resumen
Plantas de papa producidas de semilla botánica fueron infectadas en condiciones naturales por el virus del encrespamiento apical de Solanum (Solanum apical leaf curling virus—SALCV) en una estación experimental en la selva alta cerca de San Ramón, Perú. Los tubérculos de estas plantas fueron analizados en el invernadero. Los síntomas en las plantas de papa infectadas por SALCV fueron encrespamiento apical, enanismo, emergencia retardada, plantas débiles, brotes filiformes y período largo de reposo del tubérculo. Estos síntomas se parecen a una infección primaria, inusitadamente severa, con el virus del enrollamiento de las hojas de papa o a los de las enfermedades causadas por micoplasmas, como el amarillamiento del áster y otras afines. Hasta el 12% de las plantas analizadas estuvieron infectadas por SALCV de manera natural y la presencia de SALCV fue demostrada en aproximadamente la mitad de los tubérculos que produjeron brotes filiformes.
