Abstract Ecoprint is a technique that process the shape and colors of leaves, flowers, stems into media namely fabric. In this case, plants used as ecoprint are weeds. Weeds can grow in any place its existence often considered hinder due to fact it interfere other cultivated well human activities. The processing Cacabean (Ludwigia octavalvis) Ketul (Bidens pilosa) weeds raw materials for natura...

Environmental degradation and poverty are linked, and this means that conservation and poverty reduction must be tackled together. However, finding a successful integrated strategy has been an elusive goal. We describe the career of a Chinese scholar, Shixiong Cao, whose persistent efforts to find and follow win-win paths have led to ecological restoration accompanied by long-term benefits for ...

This study aimed to assess the phytotoxic potential of fleagrass (Adenosma buchneroides) on weeds and crops. We assessed effects applying aqueous extracts seed germination seedling growth three (Bidens pilosa, Paspalum thunbergia, Bromus japonicus) two crops (Oryza sativa Zea mays). The influence six doses extract was through a Petri dish experiment. qualitatively characterized using widely tar...

Pricking one cotyledon of young Bidens pilosus plants induces rapid inhibition of hypocotyl growth, essentially in its middle portion. Analysis of soluble peroxidases indicates rapid changes (increase of activity) in basic isoenzymes followed by more progressive enhancement of the acidic ones. Pretreatment of the plants with lithium prevents the inhibition of elongation due to pricking as well ...

Portulacaceae is one of 19 families of terrestrial plants in which species having C(4) photosynthesis have been found. Representative species from major clades of the genus Portulaca were studied to characterize the forms of photosynthesis structurally and biochemically. The species P. amilis, P. grandiflora, P. molokiniensis, P. oleracea, P. pilosa, and P. umbraticola belong to the subgenus Po...

Jasminanthes xuanlienensis (Apocynaceae, Asclepiadoideae), a new species from Vietnam is described, illustrated and compared with its five congeners. Jasminanthes xuanlienensis differs distinctly from congeners by the longer peduncles (14-18 cm vs. 4 cm at most in Jasminanthes pilosa and Jasminanthes saxatilis, salmon-pink color of the inner corolla lobes (white or greenish in the other species...

The species of Braunsia Kriechbaumer, 1894 (Hymenoptera, Braconidae, Doryctinae) from China are revised and ten species are recognized. Two new species, B. guangdongensissp. n. and B. shenyangensissp. n., are described and illustrated. B. fumipennis (Cameron, 1899), B. pilosa Belokobylskij, 1986, B. postfurcalis Watanabe, 1937, and B. smithii (Dalla Torre, 1898), are recorded from China for the...
