F. Mora, S. Perret, C.A. Scapim, and E. Arnhold. 2010. Genetic parameters for growth and survival in Acacia saligna shrubs. Cien. Inv. Agr. 37(2):5-14. Acacia species have valuable agronomic characteristics, such as the tolerance to unfavorable environmental conditions. In this study, genetic parameters and selection response in Acacia saligna shrubs were investigated in two arid environments o...

phenotypic and genotypic diversity as well as symbiotic effectiveness of twenty one symbionts isolated from nodules of four acacia species (acacia melanoxylon, a. mearnsii, a. saligna and acacia tortillis) grown in morocco were evaluated. growth in various media (yma, yma-bbt, yma-rc), colony morphology, tolerance to stress factors (temperature, ph, salt concentrations, various heavy metals) an...

the introduction of acacia saligna in the north nile delta of egypt is causing harmful impacts on the plant diversity. thirty stands were established in both invaded and non-invaded areas. the species abundance and diversity were determined. soil samples were collected and analyzed. the correlation between vegetation and soil variables was investigated. the allelopathic potential of water and m...

In a runoff irrigation system using levelled basins, the water uptake patterns of different plant species (Acacia saligna (Labill.) H. L. Wend. and Sorghum bicolor (L.) Moench.) with contrasting root and shoot development were compared. Rainfall amounts during 1995 led to enough runoff water for realizing two cropping cycles. The amount of irrigation water was sufficient to fill the moisture-de...

The study aimed to provide the appropriate level of Acacia Saligna (AS) for ram supplementation that enhances their reproductive performance without compromising carcass and sensory qualities.

The objective of the study was to compare the performance of exotic (Eucalyptus grandis and Acacia saligna) and indigenous (Acacia polyacantha and Bauhinia thonningii) tree species in rehabilitating active gold mine tailings dump. The seedlings were produced in a nursery and transplanted onto the tailings dumps during the rainy season in the years 2000, 2001 and 2002. The saplings were monitore...

Riparian ecosystem along rivers and streams are characterised by lateral and longitudinal ecological gradients and, as a result, harbour unique biodiversity. Riparian ecosystems in the fynbos of the Western Cape, South Africa, are characterised by seasonal dynamics, with summer droughts followed by high flows during winter. The unique hydrology and geomorphology of riparian ecosystems play an i...

Six woody legume tree species, Acacia ehrenbergiana (Hayne.), Acacia nilotica (Willd.), Acacia saligna (Labill.), Acacia tortilis (Forssk.), Acacia tortilis var. reddiana ( Savi.) and Leucaena leucocephala (Lam.) were performed the growth characteristics and to identify the resistance of native isolated Rhizobium strains from root zone surrounding trees to environmental stressesantibiotic, high...

Australian Acacia are invasive in many parts of the world. Despite significant mechanical and biological efforts to control their invasion and spread, soil-stored seed banks prevent their effective and sustained removal. In response South Africa has had a strong focus on employing seed reducing biological control agents to deal with Australian Acacia invasion, a programme that is considered as ...

Thirteen indigenous and exotic Acacia species grown in Saudi Arabia were evaluated for their host status for Meloidogyne javanica in pot tests both in the growth chamber and under outdoor conditions. In both experiments, 21-day-old seedlings were transplanted individually into 15-cm-diam. plastic pots containing a steam-sterilized mixture of equal parts loam and sandy loam. Seedlings were inocu...
