| within-plant distribution and dynamics of thrips species (thysanoptera: thripidae) in cotton. | a 2-yr study in cotton (gossypium hirsutum l.) was conducted to determine the abundance and species composition of thrips (thysanoptera: thripidae) on different plant parts throughout the season in alabama, georgia, north carolina, south carolina, and virginia. plant parts sampled included seedlings, terminals with two expanded leaves, leaves from the upper, middle, and lower sections of the canopy, white flowers, and medium-sized bolls. adult thrips were significantly more abundant on seedlings ... | 2017 | 28475718 |
| flavobacterium gossypii sp. nov. isolated from the root tissue of field-grown cotton. | a yellow-pigmented bacterial strain, jm-222t, isolated from the root tissue of field-grown cotton (gossypium hirsutum) in auburn, alabama, usa, was studied for its taxonomic allocation. cells of the isolate were rod-shaped and gram-stain-negative. a blast analysis using the eztaxon database showed that strain jm-222t shared highest 16s rrna gene sequence similarity with the type strain of flavobacterium endophyticum (98.9 %) followed by flavobacterium qiangtangense (96.7 %). 16s rrna gene sequen ... | 2017 | 28840797 |
| carbon dioxide efflux from soil with poultry litter applications in conventional and conservation tillage systems in northern alabama. | increased co2 release from soils resulting from agricultural practices such as tillage has generated concerns about contributions to global warming. maintaining current levels of soil c and/or sequestering additional c in soils are important mechanisms to reduce co2 in the atmosphere through production agriculture. we conducted a study in northern alabama from 2003 to 2006 to measure co2 efflux and c storage in long-term tilled and non-tilled cotton (gossypium hirsutum l.) plots receiving poultr ... | 2013 | 18396538 |
| accumulation of biomass and mineral elements with calendar time by cotton: application of the expanded growth model. | accumulation of plant biomass (mg ha(-1)) with calendar time (wk) occurs as a result of photosynthesis for green land-based plants. a corresponding accumulation of mineral elements (kg ha(-1)) such as nitrogen, phosphorus, and potassium occurs from the soil through plant roots. field data from literature for the warm-season annual cotton (gossypium hirsutum l.) are used in this analysis. the expanded growth model is used to describe accumulation of biomass and mineral elements with calendar time ... | 2013 | 24039802 |
| variovorax gossypii sp. nov., isolated from gossypium hirsutum. | a beige-pigmented bacterial strain (jm-310t), isolated from the healthy internal root tissue of 4-week-old cotton (gossypium hirsutum, cultivar 'des-119') in tallassee (macon county), alabama, usa, was studied taxonomically. the isolate produced small rod-shaped cells, which showed a gram-negative staining behaviour. a comparison of the 16s rrna gene sequence of the isolate revealed 99.2, 98.8, 98.7, 98.7, 98.1 and 97.6 % similarity to the 16s rrna gene sequences of the type strains of variovora ... | 2015 | 26341669 |
