At present, problems exist in walnut production in China. These include the diversity and at times low quality of available cultivars suggesting a need to simplify types and uses, the prevalence of serious diseases and the susceptibility to late frost damage. Together these are restricting the sustainable development of the industry. In the 21st century, Shandong Institute of Pomology, using intraspecific plus interspecific hybridization breeding and seedling selection, has created a collection of new walnut germplasms.

Mango Resources Information System was developed for management of phenotypic, genetic, molecular, chemical and other available information on indigenous and exotic mango cultivars. The information system is enriched with 682 accessions with the details of fruit, leaf and other characteristics. It has a collection of 26 expressed sequence tag (EST) and 285 nucleotide sequences present in mango varieties which contains complete and partial genomic sequences having the molecular type, generally genomic DNAs, m-RNAs and unassigned DNAs.

The role of urban parks in the microclimatic conditions of cities in summer is investigated in this paper through monitoring campaigns carried out at the Beijing Olympic forestry park. Five kinds of land cover, namely urban woods, lawn, bare concrete cover, water areas and wetlands were selected to study on the temperature, humidity and human comfort. The air temperature and relative humidity were measured once every two hours from 8:00 to 20:00 every day and continuously three days in July 2010.
