Occurrence of nodulation in the Leguminosae [PDF]

New Phytologist, 1989
summaryReports of nodulation in the Leguminosae are examined in the light of current views on the taxonomy of the family. In the subfamily Caesalpinioideae, nodulation is largely restricted to the tribe Caesalpinieae and the genus Chamaecrista from the Cassieae.

Desenvolvimento de espécies arbóreas em sistemas agroflorestais para recuperação de áreas degradadas na floresta ombrófila densa, Paraty, RJ

Revista Árvore, 2013
Os sistemas agroflorestais implantados consistiram da combinação de espécies leguminosas e não leguminosas em plantio "solteiro" (uma planta/cova) e "casado" (duas plantas/cova). Aos quatro anos após o plantio, foram realizadas medições de circunferência

Determination of the capability of common bean “amachamiento” (Aphelenchoides besseyi Christie) of being seed-transmitted.

Agronomía Mesoamericana, 2015
The objective of this research was to determine the capability of Aphelenchoides besseyi of being seed-transmitted in common bean. During 2007 and 2008, seeds were collected from nematode-infested common bean plants (cv.

Resistance mechanisms in collard green genotypes to Plutella xylostella: role of physical and morphological traits

Pest Management Science, Volume 82, Issue 2, Page 1974-1984, February 2026.
Resistance to Plutella xylostella in collard greens is mediated by antixenosis and antibiosis, associated with traits such as leaf wax, hardness, and color. Genotypes showed strong resistance potential, supporting their use in breeding and integrated pest management strategies. Abstract BACKGROUND The diamondback moth, Plutella xylostella (Lepidoptera:

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...

Can the physical‐hydraulic properties of degraded soil be improved using polymers?

Soil Science Society of America Journal, Volume 89, Issue 6, November/December 2025.
Abstract For a degraded soil it is assumed that improvements in key physical‐hydraulic properties occur at an optimum superabsorbent polymer (SAP) application rate, following repeated wetting and drying cycles. A column experiment was carried out in a shade house (Ceará State, Brazil), following a completely randomized design, in a 6 × 4 factorial ...
