Fragmentation of Cotton Bract and a Technique for Detecting Bract in Cotton Dust¹

Agronomy Journal, 1978
AbstractBract fragments are thought to be a major component of the respirable dust generated during the processing of cotton (Gossypium sp.) lint in textile mills. Byssinosis is an occupational disease affecting susceptible textile workers exposed to respirable dust. Procedures designed to reduce mill dust require that the dust components be identified.

Multifunctionality of angiosperm floral bracts: a review

Biological Reviews
ABSTRACTFloral bracts (bracteoles, cataphylls) are leaf‐like organs that subtend flowers or inflorescences but are of non‐floral origin; they occur in a wide diversity of species, representing multiple independent origins, and exhibit great variation in form and function.

Polygenic Inheritance of Bracts Number in Sunflower

Helia, 2019
Abstract Two inbreds of mutant origin, differing in the number of bracts, were crossed to obtain the F1 hybrid. One mutant line had 24.5 ± 1.01 bracts, while the other, 78.6 ± 1.69 bracts. The F1 hybrid had an average value between parents, which practically did not differ from the mean value in the F2 population.

Selection against the bracting defect of cauliflower

Euphytica, 1975
The appearance of bracts through the surface of the cauliflower curd had a heritability estimate of 0.73 ± 0.10 based on the regression of progeny on parent when grown under field conditions. When curds were taken from field grown plants and aseptically cultured, their bracting characteristics were enhanced.

Evolution of bract development and B‐class MADS box gene expression in petaloid bracts of Cornus s. l. (Cornaceae)

New Phytologist, 2012
Despite increasing interest in the molecular mechanisms of floral diversity, few studies have investigated the developmental and genetic bases of petaloid bracts. This study examined morphological patterns of bract initiation and expression patterns of B-class MADS-box genes in bracts of several Cornus species.

Araucaria bract-scale complex and associated foliage from the early-middle Eocene of Antarctica and their implications for Gondwanan biogeography

Historical Biology, 2018
The early-middle Eocene Fossil Hill flora from King George Island in the Antarctic Peninsula regions is one of the most diverse Cenozoic plant assemblages in Antarctica. It represents a rich Nothofagus and conifer dominated vegetation.

Hop Bract Polyphenols Reduced Three-day Dental Plaque Regrowth

Journal of Dental Research, 2007
Previous research has shown the inhibitory effects of hop bract polyphenols (HBP) on cariogenic streptococci in vitro, but their effects in humans have not been investigated. This double-blind, crossover clinical study tested the hypothesis that HBP delivered in a mouthrinse suppresses plaque regrowth in humans. Twenty-nine healthy male volunteers had

Research on Degumming Experiment of Corn Bracts

Advanced Materials Research, 2012
In this paper, using chemical degumming method on corn bract fiber degumming experiment, in order to find a more suitable degumming process of corn bracts and to realize the development and utilization of corn bract fiber. "Pre-oxygen pretreatment + Two scouring" chemical degumming method was used, and the optimal combination of process parameters was ...
