Schizolobium Parahyba

Abstract S. parahyba is a fast growing tree, and is used widely in mixed plantations in Brazil for land reclamation, environmental purposes and also as an ornamental and shade tree. In some South American countries the species is used in agroforestry systems. In Ecuador, it has been planted since the 1980s for timber production; there are currently about 12,000 ha. Its low quality wood is mainly used for light boxes (such as for packing fruits) and corestock veneers. It is considered excellent for pulp and short-fibre paper production, with fibre length varying from 1.10 to 1.59 mm.

Fibre Characteristics

In single-coated animal species selected for fibre production, such as sheep and Angora goats, nutrition is known to have a positive effect on fibre length and diameter, and hence on the weight of fibre produced, while in double-coated species, such as the cashmere goat, the fibre characteristics of the undercoat appear relatively insensitive to nutritional influence. Recent studies on the relationship between nutrition and fibre production in the llama, a double-coated species, indicate that it conforms to the above generalisation in that the growth rate and diameter of its fibre are not amenable to nutritional manipulation (Russel and Redden, 1994). There is a lack of information on the effects of nutrition on fibre characteristics and production in the other domesticated species of South American camelid, the single-coated alpaca. The experiment reported here was designed to provide such information.

Abstract Farmers’ households in upstream watersheds in Indonesia experience crop failure in their business cultivation as a result of climate change. The aim of this study, knowing the level of farmer resilience in various agroforestry systems of mixed gardens – talun developed in various agroforestry systems of mixed gardens – talun developed on the highlands in the upstream Minraleng sub-watershed. Data collection was carried out through observation and interviews with farmer household respondents. The results showed that farmer households developed an intercropping agroforestry system of teak and corn in the first phase (1-4 years) and mixed plantations of bananas, cacao and papaya in the second phase (4-15 years), and continued with mixed plantations dominated by teak, have a higher adaptive capacity and levels of resilience to climate change. This is because it has more diversity of plants and a variety of livelihoods, and has the power of mutual association between plants in dealing with drought.

Coppice Management

Coppice management is an ecologically important silvicultural practice to provide the quicker and higher potential of wood biomass production for industrial demands. Understanding morphological and anatomical responses of coppiced trees could help to determine the quantity and quality of wood and thus provide better management of coppiced tree plantations for short-time biomass production. However, there is a little investigation in morphological and anatomical adaptation in different fast-growing tree species. The present study, therefore, studied how morphology and anatomy vary between two fast-growing coppices of Populus nigra L. (black poplar) and Salix alba L. (white willow). Each coppiced tree was grown in a similar habitat and was at a similar age. However, each coppiced tree showed different morphological and anatomical plasticity in their stems in response to environmental factors. Poplar coppices showed better anatomical properties due to greater vessel diameter, fibre length, fibre width, fibre wall thickness, and ray height; however willow coppices had better morphological plasticity which had higher average stem height and ring width. The results suggest that willow coppices had the greater height growth potential even at 2 years of age than poplar coppices.

Shade Tree

Cacao agroforestry systems offer the potential to diversify farmer income sources, enhance biodiversity, sequester carbon, and deliver other important ecosystem services. To date, however, studies have emphasized field- and system-scale outcomes of shade tree integration, and potential impacts on the rhizosphere of adjacent cacao trees have not been fully characterized. Interactions at the root–soil interface are closely linked to plant health and productivity, making it important to understand how diverse shade tree species may affect soil fertility and microbial communities in the cacao rhizosphere. We assessed the impacts of neighboring shade tree presence and identity on cacao yields and physical, chemical, and biological components of the cacao rhizosphere in a recently established diversified agroforestry system in South Sulawesi, Indonesia. Stepwise regression revealed surprising and strong impacts of microbial diversity and community composition on cacao yields and pod infection rates. The presence of neighboring shade trees increased nitrogen, phosphorus, and pH in the rhizosphere of nearby cacao trees without yield losses. Over a longer time horizon, these increases in rhizosphere soil fertility will likely increase cacao productivity and shape microbial communities, as regression models showed nitrogen and phosphorus in particular to be important predictors of cacao yields and microbiome diversity and composition. However, neither presence nor identity of shade trees directly affected microbial diversity, community composition, or field-scale distance-decay relationships at this early stage of establishment. These results highlight locally specific benefits of shade trees in this agroecological context and emphasize the rhizosphere as a key link in indirect impacts of shade trees on cacao health and productivity in diversified systems.

Abstract P. tomentosa is one of the most important tree species in China. It is a fast-growing tree with high-quality wood, and produces approximately 0.4 cubic metres of timber after 10 years' growth. Currently there are about 1.1 billion Paulownia trees planted throughout China and about 3.0 million cubic metres of Paulownia timber worth US$55 million is exported overseas each year; P. tomentosa represents a substantial proportion of this. The wood is used in furniture, decorative products and musical instruments. P. tomentosa is also suitable for use in agroforestry systems in semi-humid temperate areas. A disadvantage is that this species grows well only on fertile land. More research is needed in order to improve its wood properties and stress tolerance, and increase its use in plantations.
