Abstract

Arrangement of Guava Flowering (Psidium guajava L.) ‘Krystal’ through the Application of Different Strangulation Times. The seasonal production of guava (Psidium guajava) requires flowering manipulation technique such strangulation in order to be available throughout the years. This study aimed to explain the relationship between strangulation time, the period of flowering and harvesting of guava cv 'Krystal'. The experiment was conducted from February to December 2017, in Cikabayan experimental garden of IPB University, Bogor, Indonesia. The experiment used a completely randomized design with single factor, i.e strangulation times that consisted of control (no strangulation), strangulation in March, in April and in May. The results showed that strangulation treatment was able to accelerate the emergence of flowers and increase the number of generative shoots, the number of flowers per tree and the number of fruits harvested. The increase of flowering response on strangulated trees was supported by a higher leaf C/N compared to control, which is related to the low leaf N content in strangulation treatments. The strangulation treatment could accelerate the time of flower emergence six days earlier than control. Keywords: guava, C/N, flowering induction, ringing, seasonal production
