Arboriculture

Premise: Pollinator sharing of co-flowering plants may result in interspecific pollen receipt with a fitness cost. However, the underlying factors that determine the effects of heterospecific pollen (HP) are not fully understood. Moreover, the cost of stigma closure induced by HP may be more severe...

In the south of the Russian Far East, an alien North American species Nematus tibialis Newman, 1873 was registered for the first time. The insect develops on the main food plant, Robinia pseudoacacia L., cultivated in the settlement of Gorno-Taezhnoye and in the arboretum of the Gorno-Taezhnaya...

Gibberellin (GA) is frequently used in tree peony forcing culture, but inappropriate application often causes flower deformity. Here, 5-azacytidine (5-azaC), an efficient DNA demethylating reagent, induced tree peony flowering with a low deformity rate by rapidly inducing PsFT expression, whereas...

A new distribution map is provided for Macrohomotoma gladiata Kuwayama. Hemiptera: Homotomidae. Hosts: ornamental Ficus spp. especially F. macrocarpa. Information is given on the geographical distribution in Africa (Algeria, Morocco, Tunisia), Asia (China, Fujian, Shanghai, Hong Kong, India,...

Trees and greenspaces are valuable as part of urban areas for many reasons, including improving air quality, providing spaces and corridors for...

This review of tree biomechanics covers recent research publications that offer new insights into how trees respond to mechanical loads and resist failure, especially in winds. Biomechanical studies using dynamic rather than static structural methods are showing that the form of the tree influences...

Roses are one of the most highly produced and purchased ornamental plants worldwide. Procurement and preservation of pollen is essential for the production of diverse rose varieties. In this study, we analyzed pollen management conditions, such as the pollen collection stage, drying time, and...
