Adopt principal component regression for researching the optimal subsidy mode of cotton production in China. The result indicates that, from the perspective of economic stimulatory effect, the optimal cotton subsidy in China is farm chemical subsidy rather than seed subsidy. The reason is that there are frequent pest disasters in cotton producing areas in China. So farm chemical subsidy is the ...

an ex-situ experiment to assess the metal extractive potential of fourteen agriculture plants (vigna unguiculata, gossypium hirsutum, jatropha curcas, etc.) was conducted on magnesite mines which had above permissible levels of cadmium and lead. there was no much difference in the total chlorophyll a and b, carbohydrate and protein contents in the plants grown in the mining soil and adjacent co...

In this work, morphological and anatomical features of seeds 15 Alyssum taxa (A. caricum, A. davisianum, filiforme, haussknechtii, murale subsp. var. murale, simplex, sibiricum, desertorum, hirsutum hirsutum, minutum, strictum, strigosum strigosum, szowitsianum, dasycarpum linifolium linifolium) from Turkey were examined with the cluster analysis, systematic importance these characteristics was...

The germination stimulants for root parasitic plants Striga and Orobanche produced by cotton (Gossypium hirsutum L.) were examined in detail. Seeds of cotton were germinated and grown on glass wool wetted with sterile distilled water in sterile filter units. The root exudate was collected daily and extracted with ethyl acetate. Each of these ethyl acetate extracts was analyzed directly by high-...

Kinetics and osmoregulation of cotton (Gossypium hirsutum L.) fiber growth (primarily extension) have been studied. Growth is dependent on turgor pressure in the fiber. It is inhibited when a decrease in the water potential of the culture medium due to an addition of Carbowax 6000, equals the turgor pressure of the fiber. Potassium and malate accumulate in the fiber and reach peak levels when t...

Effective use of Gossypium hirsutum L. lines in cotton genetic improvement programs depends on the extent of genetic variation for desirable alleles and the accurate characterization of the variability among germplasm accessions. Marker assisted selection has provided the potential for efficient development of disease and pest resistant plants. Association mapping is used to identify chromosoma...

A putative advantage of allopolyploidy is the possibility of differential selection of duplicated (homeologous) genes originating from two different progenitor genomes. In this note we explore this hypothesis using a high throughput, SNP-specific microarray technology applied to seed trichomes (cotton) harvested from three developmental time points in wild and modern accessions of two independe...

Single-celled cotton fiber (Gossypium hirsutum) provides a unique experimental system to study cell elongation. To investigate the role of the actin cytoskeleton during fiber development, 15 G. hirsutum ACTIN (GhACT) cDNA clones were characterized. RNA gel blot and real-time RT-PCR analysis revealed that GhACT genes are differentially expressed in different tissues and can be classified into fo...
