Micropropagation of Calathea ornata Koern.

Biologia plantarum, 1997
In vitro cultures of Calathea ornata Koern. cv. Sanderiana shoots were maintained on modified medium of Murashige and Skoog. With the aim to find effective micropropagation method the effects of cytokinins, paclobutrazol, saccharose, mineral salts and shoot-tip damage on the shoot growth and quality were studied.

Extraction and Comprehensive Characterization of Starch From Ryegrass (Lolium multiflorum L.) Seeds as a Non‐Conventional Source

Starch - Stärke, Volume 78, Issue 1, January 2026.
A native starch was extracted from ryegrass (Lolium multiflorum L.), yielding a high‐purity product with a significant starch content. The starch exhibited type A and V crystallinity, with a mean particle size (D50) ~7 nm, high swelling power, and low retrogradation tendency.

Bulbil formation in stress: Crucial role of triploid fitness in mixed ploidy dynamics in Costus speciosus

Plant Species Biology, Volume 41, Issue 1, January 2026.
Upon prolonged waterlogging, a Costus speciosus plant developed bulbils at stem node. Karyotype analysis, nucleolar staining, and anatomical study revealed its triploid status and developmental aspects. Prevalence of tetraploid, abundance, and unique reproductive fecundity of the triploid, indicates its determinant role in coexistence of the multiple ...

A Conservation Assessment and Phylogenomic Evaluation of Protection Status in the Tropical Genus Heliconia L. (Zingiberales: Heliconiaceae)

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1438-1457, September 2025.
The primarily neotropical plant genus Heliconia has been cultivated commercially in gardens and nurseries for hundreds of years. Many of these same species are ecological keystones in their native habitats as important resources for herbivorous insects and pollinating hummingbirds, yet they face threats of habitat loss and degradation, competition with

Niche packing, but not niche expansion, explains the co‐occurrence of hummingbirds‐visited plants

Ecography, Volume 2025, Issue 6, June 2025.
Tropical mountains often harbour high species richness. Yet the mechanisms behind such high richness remain poorly understood. One prominent hypothesis for high species richness is niche partitioning, which reduces competition and promotes coexistence.

Reasons of leaves withering in tropical plants cultivated under greenhouse conditions

Acta Agrobotanica, 2013
In order to determine the reasons of necrosis of exotic plants leaves cultivated in greenhouses plants belonging to ten following species were examined: Ceratozamia mexicana Brongn., Stangeria eriopus (Kunze) Nash (Cycadaceae), Eriobotrya japonica Lindl.

Pest categorisation of Selenaspidus articulatus

EFSA Journal, Volume 23, Issue 5, May 2025.
Abstract Following the commodity risk assessment of Jasminum polyanthum unrooted cuttings from Uganda, in which Selenaspidus articulatus (Hemiptera: Diaspididae) was identified as a pest of possible concern, the European Commission requested the EFSA Panel on Plant Health to conduct a pest categorisation of S.

Anti‐Motion Artifacts Iontronic Sensor for Long‐Term Accurate Fingertip Pulse Monitoring

Advanced Science, Volume 12, Issue 15, April 17, 2025.
Flexible pressure sensors are essential for pulse monitoring and cardiovascular disease diagnosis but are affected by motion artifacts (MAs) due to stretching stress. The S‐smooth sensor with a soft‐hard stretchable interface that dissipates energy, reducing MAs by 90% is developed.

Pyriculariopsis calatheae sp. nov., a novel anamorphic hyphomycete from the Atlantic forest of Brazil causing leaf spots on Calathea longifolia

Mycological Progress, 2010
The new species Pyriculariopsis calatheae is described causing leaf spots on Calathea longifolia (Marantaceae). It represents an addition to the mycobiota of the tropical seasonal semi-deciduous montane forest, a component of the Brazilian Atlantic forest and a highly threatened ecosystem.
