Two parental lines of Upland cotton (Gossypium hirsutum L.) plus their reciprocal F(1), F(2), and backcross populations were field-tested for environmental and genetic components of leaf diffusive resistance. Leaf resistance was measured with a diffusion porometer three times each day during 6 days in August. A large, consistent environmental component was present during the morning, afternoon,...

High residue conservation tillage systems for cotton (Gossypium hirsutum L.) production have been proposed as having the potential to be both economically and environmentally sustainable, and research regarding till­ age systems has indicated that several advantages may exist for conservation tillage systems compared to con­ ventional tillage systems. However, adoption of new farming systems on...

A detailed restriction fragment length polymorphism map was used to determine the chromosomal locations and subgenomic distributions of quantitative trait loci (QTLs) segregating in a cross between cultivars of allotetraploid (AADD) Gossypium hirsutum (‘‘Upland’’ cotton) and Gossypium barbadense (‘‘Sea Island,’’ ‘‘Pima,’’ or ‘‘Egyptian’’ cotton) that differ markedly in the quality and quantity ...

Kapas Gossypium hirsutum adalah anggota keluarga Malvaceae, dan biji serta daunnya telah banyak digunakan untuk perawatan kesehatan. G. memiliki metabolit sekunder berupa flavonoid, tanin, saponin steroid yang dapat memberikan efek farmakologis. Penelitian ini bertujuan mengetahui perbandingan toksisitas antara ekstrak etanol daun kersen (Muntingia calabura) kapas (Gossypium hirsutum) menggunak...

The DNA content of eukaryotic nuclei (C-value) varies approximately 200,000-fold, but there is only a approximately 20-fold variation in the number of protein-coding genes. Hence, most C-value variation is ascribed to the repetitive fraction, although little is known about the evolutionary dynamics of the specific components that lead to genome size variation. To understand the modes and mechan...
