TLDR
Seasonal cycle of cambial activity was compared among the trees of Azadirachta indica growing in Moist Deciduous (MDF), Dry Decidulent (DDF) and Scrub land Forest (SF) of Gujarat State and vascular cambium was discussed in relation to phenology and local climatic conditions.Abstract:
Seasonal cycle of cambial activity was compared among the trees of Azadirachta indica growing in Moist Deciduous (MDF), Dry Deciduous (DDF) and Scrub land Forest (SF) of Gujarat State. Radial growth occurred in two growth flushes in MDF and DDF. Cambial cell divisions in MDF started in February and June resulting maximal radial growth in August-September when the rains were heavy and ceased in January and May during the drier part of the year. In DDF the first flush of growth commenced in January with maximal xylem development in April and ceased in May. The second flush of cambial activity began in June with the arrival of rains, reached peak in October and ceased in December. Cambium was active throughout the year in SF and attained its peak activity thrice i.e. in February, July and October. With complete maturation of leaves in November, the cell divisions were rather slow in MDF and SF whereas no divisions were encountered in DDF. Cambial rays exhibited large intercellular spaces during drier months in all the three fo- rests. Seasonal behavior of vascular cambium was discussed in relation to phenology and local climatic conditions.read more

Seasonal development of secondary xylem and phloem in Schizolobium parahyba (Vell.) Blake (Leguminosae : Caesalpinioideae)
TL;DR: The relationship between seasonal cambial activity, xylem and phloem development, and phenology in Schizolobium parahyba, a fast growing semideciduous seasonal forest tree from southeastern Brazil, is described.
PART OF A HIGHLIGHT ON TREE BIOLOGY Fluctuations of cambial activity in relation to precipitation result in annual rings and intra-annual growth zones of xylem and phloem in teak (Tectona grandis) in Ivory Coast
TL;DR: The seasonal formation pattern and microstructure of teak xylem suggest that AXGRs and XGZs can be used as proxies for analyses of the tree history and climate at annual and intra-annual resolution.

TL;DR: In this article, the structural variations of tree rings and their periodicity of formation are known, which can be used to carry carbon sequestration and climate information in the tropics.

TL;DR: It was evident that the monthly mean minimum temperature plays an important role for the cambial activity and xylem production rather than influence by rainfall and relative humidity in D. indica L. (Dilleniaceae) growing in sub-tropical wet forest of Meghalaya state, India.

TL;DR: It is concluded that classical dendrochronological methods (ring width measurements) should not be applied to A. marina (from Kenya) and more than one cambium was found to be simultaneously active.
