This study aimed at carrying out the vegetative propagation of Griffonia simplicifolia. This was achieved by growing nodal and stem cuttings of G. simplicifolia using two types of soils under varying environmental conditions including open area and humidity propagator. This revealed that terminal nodal stem cuttings showed the best growth forms in terms of shoot development as well as root development when subjected to open area and topsoil. However, when subjected to the humid propagator and river sand, the distal stem cuttings gave the best growth forms thereby promoting shoot and root development. Hence, it is concluded that the terminal nodes are the best parts to be used for the propagation of G. simplicifolia and the best growth medium is river sand. Furthermore, this research demonstrates that G. simplicifolia can be reproduced through macro propagation using stem cuttings and it can be seen as a basis for conservation and other breeding research on G. simplicifolia.

Abstract Kayu ules (Helicteres isora) or screw tree has bioactive compounds benefiting for anti-diabetes, antioxidant and antibacterial. In Indonesia, the fruits have been commercially harnessed for traditional medicine. The benefit of kayu ules has attracted some farmers to evolve this species in their garden, however, the domestication technique has not mastered well yet. Therefore, this study aimed to domesticate kayu ules under a home garden (HG) and analyze the feasibility of cultivating kayu ules through stem cuttings. Kayu ules development underwent two split HG’s: tree shade (HG1) and open area (HG2). Other nursery performances at each home garden were made with no shade (N1), with shading net (N2) and a coco-leaf shade (N3). The result showed that within 60 days on HG1, the best survival was on N2 with 76% of survival and declined on N1 at 30%. Conversely, under HG2, N1 gave the best survival compared to N2, 81% and 46% each. Meanwhile, N3 was in between N1 and N2 on HG1 (56%) and HG2 (58%). The shading treatments, which allowed 20 to 40 % sunlight to pass through, effectively increased the survival of stem cuttings. According to an online market platform at the highest price, nursery N1 delivered the highest IRR at 106% and the second was on N3, followed by N2, which were 104% and 85%, respectively.

This paper presents a study of patterns in the distribution and transmission of medicinal plant knowledge in rural Andean communities in Peru and Bolivia. Interviews and freelisting exercises were conducted with 18 households at each study site. The amount of medicinal plant knowledge of households was compared in relation to their socioeconomic characteristics. Cluster analysis was applied to identify households that possessed similar knowledge. The different modes of knowledge transmission were also assessed. Our study shows that while theamountof plant knowledge is determined by individual motivation and experience, thetypeof knowledge is influenced by the community of residence, age, migratory activity, and market integration. Plant knowledge was equally transmitted vertically and horizontally, which indicates that it is first acquired within the family but then undergoes transformations as a result of subsequent contacts with other knowledge sources, including age peers.

Homeostasis Theory

Climate change is having profound influences on Arctic tundra plant composition, community dynamics, and ecosystem processes. Stoichiometric homeostasis (H), the degree to which a plant maintains its internal nutrient concentrations independent of nutrient variations in its environment, may be a useful approach to predict the impacts of these influences. In this case study, we used fertilization manipulation data to calculate homeostasis indices based on nitrogen (HN), phosphorus (HP), and nitrogen to phosphorus ratios (HN:P) of aboveground tissues for seven common tundra vascular species belonging to three growth forms. We then analyzed species H relationships with dominance, spatial stability, and responsiveness to various experimental manipulations. Each of the H indices was correlated amongst tissue types within each species and was generally highest in ericoid mycorrhizal host species and lowest in the ectomycorrhizal birch. Species HP and HN:P were consistently positively correlated with aboveground biomass within the controls and across all manipulations. Furthermore, these same species were spatially stable across experimentally warmed field plots. Stoichiometric homeostasis theory has been successful in predicting grassland community dynamics. This first test of its applicability across a variety of Arctic plant growth forms highlights its considerable potential in predicting tundra plant community structure and responses to environmental change.
