Forests are dynamic ecosystems that constantly changing. The most common natural reasons for change in forests the growth and death of trees, as well damage occurring to them. Tree appears an increment its structural dimensions, such stem diameter, height, crown volume, which all affect structure a tree. Repeated measurements tree characteristics enable observations respective increments indica...

Understanding how tropical tree species differ in their growth strategies is critical to predict forest dynamics and assess species coexistence. Although tree growth is highly variable in tropical forests, species maximum growth is often considered as a major axis synthesizing species strategies, with fast-growing pioneer and slow-growing shade tolerant species as emblematic representatives. We...

Increased tree growth in temperate and boreal forests has been proposed as a direct consequence of a warming climate. Acid deposition effects on nutrient availability may influence the climate dependency of tree growth, however. This study presents an analysis of archived soil samples that has enabled changes in soil chemistry to be tracked with patterns of tree growth through the 20th century....

Control of tree size is one of the main problems for which techniques to reduce vegetative growth and increase fruit quality and yield are important in the orchard management system. With this aim in mind, mature peach trees of the cultivars J. H. Hale and Red Skin grown on peach seedling at the Moghan agro industrial orchard were used. The effect of paclobutrazol soil treatments, (0,0.5 and 1....

date palm tree reaction to fertilizer is very slow, due to the trunk nutrients. this fact leads to farmer unwillingness to feed the trees. however, balance fertilizing improves vegetative growth and reduce the period for flowering. this study aimed to assess the effects of manure, chemical and organic sulfur on vegetative characteristics of ‘piarom’ date palm offshoot in a randomized complete b...
