Objective: To describe Heliconia uxpanapensis x latispatha var. Karely, interspecific variety generated for cut flower based on commercial standards. Design/Methodology/Approach: Interspecific hand pollination was carried out between H. Gutiérrez Báez Benth. The female parent is endemic to Mexico; it presents compact growth due its pachymorphic rhizome, red and erect inflorescence, bracts in di...

Dalechampia is a mainly South American genus of generally climbing shrubs with usually sharp stiff trichomes in some the inflorescence parts. The bisexual inflorescences are very condensed and subtended by two, often showy, large bracts. three pistillate flowers separate from staminate subinflorescence (both groups their own bracts). contains staminodial-like bractlets that provide resin for fe...

Abstract Background Walnut anthracnose caused by Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is an important walnut production problem in China. Although the long non-coding RNAs (lncRNAs) are for plant disease resistance, molecular mechanisms underlying resistance to C. remain poorly understood. Results The anthracnose-resistant F26 fruits from B26 clone anthracnose-susceptible F423...

Ecological restoration of rangelands using wild-collected seeds can be challenging due to low seed quality, inconvenient anatomy, and poor plant establishment. In North America, the half-shrub winterfat (Krascheninnikovia lanata) is a valuable protein-rich forage for wildlife livestock. Seeds this species are contained in one-seeded fruits enclosed four fluffy, silky bracts. While removed from ...

PREMISE OF THE STUDY Investigations of inflorescence architecture offer insight into the evolution of an astounding array of reproductive shoot systems in the angiosperms, as well as the potential to genetically manipulate these branching patterns to improve crop yield and enhance the aesthetics of horticultural species. The diversity of inflorescences in the economically important family Oleac...

Crude and purified aqueous extracts of cotton bracts shown to cause airway constriction in naive subjects were assayed for endotoxin content. Pulmonary function measured by flow changes on partial expiratory flow volume curves was used to assess airway responses to the bract extracts after their inhalation by a panel of volunteers. These responses are similar to the acute responses experienced ...

BACKGROUND AND AIMS Helichrysum bracteatum is called an 'eternal flower' and has large, coloured, scarious bracts. These maintain their aesthetic value without wilting or discoloration for many years. There have been no research studies of cell death or cell morphology of the scarious bract, and hence the aim of this work was to elucidate these characteristics for the bract of H. bracteatum. ...
