“…Finalmente, los árboles afectados por defoliaciones de procesionaria fueron capaces de recuperar los valores de crecimiento previos a las defoliaciones. Esta recuperación posterior a las defoliaciones ha sido observada por otros estudios en términos de crecimiento (Linares et al 2014) y disponibilidad de carbohidratos no estructurales (Palacio et al 2012).Tras la sequía severa de 1985-1986 todos los individuos de Abies alba mostraron una fuerte reducción del crecimiento, independientemente de la presencia o del tipo de hongo patógeno de raíz (Fig. 4).…”

“…A few studies have investigated how repeated defoliation or disturbance affects NSC. For several months after a defoliation event, young Eucalyptus plants did not experience carbon limitation (5), and repeated defoliation events (spaced by several years of canopy recovery) led to an accumulation of NSC in Pinus nigra Arnold (96). In contrast, there is evidence of carbon limitation in root systems of mature Populus after repeated defoliation (70), but much more research should be done in terms of disturbance intensity/severity and legacy effects on carbon storage and remobilization of NSC pools in woody plants (56,136).…”

Nonstructural carbon (NSC) provides the carbon and energy for plant growth and survival. In woody plants, fundamental questions about NSC remain unresolved: Is NSC storage an active or passive process? Do older NSC reserves remain accessible to the plant? How is NSC depletion related to mortality risk? Herein we review conceptual and mathematical models of NSC dynamics, recent observations and experiments at the organismal scale, and advances in plant physiology that have provided a better understanding of the dynamics of woody plant NSC. Plants preferentially use new carbon but can access decade-old carbon when the plant is stressed or physically damaged. In addition to serving as a carbon and energy source, NSC plays important roles in phloem transport, osmoregulation, and cold tolerance, but how plants regulate these competing roles and NSC depletion remains elusive. Moving forward requires greater synthesis of models and data and integration across scales from -omics to ecology. 667

“…Hal tersebut sebagai akibat dari menurunnya proses fotosintesis yang disebabkan oleh berkurangnya volume daun yang menjadi tempat berprosesnya kegiatan tersebut. Pada kondisi defoliasi berat dan terjadi secara berulang dampaknya pada tanaman menjadi jauh lebih besar, yaitu kehilangan pertumbuhan hingga kematian (Palacio et al, 2012;Simmons et al, 2014). Pada tanaman konifer, kehilangan pertumbuhan akibat defoliasi bervariasi antara 10-80%, tergantung tingkat defoliasi dan pertumbuhan tanaman (Jacquet et al, 2012).…”

The gregarious caterpillars of Heortia vitessoides Moore is a major defoliator of agar trees. The pest seriously threatens the existing agar tree plantation that has been widely cultivated in the community. Pest attacks began to occur in Indonesia since 2005, resulting in the damage and death of agar tree plants in various regions.To determine the impact of pest attack, a study was conducted through periodic monitoring at agar plantation in Carita Forest Research Station (CFRS), Banten Province, from April 2012 to March 2015. Monitoring was conducted in three plots of agar plantations. Each plot consists of six permanent subplots and in each subplot 15 samples of agar tree were randomly choosen. Data were collected and analyzed on monthly basis according to the intensity of defoliation and the mortality of agar trees. Defoliation intensity was determined by the percentage number of trees suffering defoliation in four damage categories, i.e.: light (10-25%), moderate (25-50%), heavy (50-75%), and severe (75-100%). Tree mortality was calculated as the annual percentage of dead trees. The study showed that the defoliation occurred throughout the year in varying degrees of damage. The monthly percentage of defoliated trees is about 30-70% annualy. The high percentage of tree defoliation mainly occurs during dry and early rainy season (June-December). Higher percentage of heavy and severe defoliations were found mostly at seedling. Repeated heavy defoliation causes stunted growth and tree mortality. Early monitoring and control of pests are very important to be done regularly to prevent the damage wider and heavier.
