Description

Abstract Purple passionfruit plants were grown at 23 18 , 28 23 and 33 28 ° C . Shoot growth was maximum at 33 28 ° C owing to the increased lateral growth. At 23 18 ° C , no laterals developed and some flowers were newly formed. High temperature accelerated flower development. Fruit set increased with the decrease in temperature. Fruit matured very rapidly and the juice content was highest at 28 23 ° C . The values for fruit weight and juice content were lowest at 33 28 ° C . Sugar content in the juice was highest at 28 23 ° C and lowest at 33 28 ° C . Sucrose accumulated more at 23 18 ° C , while the glucose and fructose contents increased at higher temperatures. These results indicate that relatively low temperatures are suitable for flowering and fruit set, and moderately high temperatures are favorable for fruit growth and quality in purple passionfruit.
