Abstract
Studies were performed to determine the effect that plant hormones involved with plant senescence (i.e., ethylene and abscisic acid) and photoperiod have on disease development and symptom expression of bacterial ring rot (BRR) caused byCorynebacterium sepedonicum (Spieck & Kotth.) Skapt & Burkh. Potato plants were grown either under a long (14 hr.) or short (10 hr.) photoperiod, while eggplants were grown only under a short (10 hr.) photoperiod. Disease severity ratings of BRR were found to be significantly higher (P=0.05) on potato plants grown under a short photoperiod compared to a long photoperiod. Plant heights of BRR infected plants were found to be significantly greater under the long photoperiod. Endogenous levels of ethylene were found to be significantly (P=0.05) greater in inoculated potato plants grown under a long photoperiod than inoculated plants grown under a short photoperiod. Results suggest that the plant hormones ethylene and abscisic acid do not significantly affect the disease development and symptom expression of BRR.
Compendio
Se llevaron a cabo estudios para determinar el efecto que tienen las hormonas vegetales involucradas en la senescencia de las plantas (v.gr. el etileno y el ácido abscísico) y en el fotoperiodo sobre el desarrollo y expresión de sÍntomas de la pudrición anular bacteriana (BRR) causada porCorynebacterium sepedonicum (Spieck & Kotth.) Skapt and Burkh. Las plantas de papa crecieron bajo un fotoperiodo largo (14 hr) o corto (10 hr), mientras que las de berenjena crecieron solamente bajo un fotoperiodo corto (10 hr). Se encontró que los grados de severidad de la pudrición fueron significativamente mayores (P = 0,05) sobre las plantas de papa crecidas bajo un fotoperiodo corto en comparación con un fotoperiodo largo. Las alturas de las plantas infectadas con BRR fueron significativamente mayores bajo el fotoperiodo largo. Se encontró que los niveles endógenos de etileno fueron significativamente (P=0,05) mayores en las plantas de papa inoculadas y crecidas bajo un fotoperiodo largo que en las que crecieron bajo un fotoperiodo corto. Los resultados sugieren que las hormonas vegetales etileno y ácido abscÍsico no afectan significativamente el desarrollo y la expresión de sÍntomas de la pudrición anular bacteriana (BRR).
