Sorghum bicolor (L.) Moench is an important grain and forage crop grown worldwide. We developed a simple sequence repeat (SSR) linkage map for sorghum using 352 publicly available SSR primer pairs and a population of 277 F2 individuals derived from a cross between the Westland A line and PI 550610. A total of 132 SSR loci appeared polymorphic in the mapping population, and 118 SSRs were mapped ...

Beef and dairy industries form the base of livestock production in New Mexico. In 2003, Curry, Roosevelt, and Chaves counties accounted for over 48% of all livestock cash receipts in the state (New Mexico Agricultural Statistics, 2003). Milk is the state’s number one cash commodity, producing over $790 million in 2003; and these three counties accounted for over 63% of milk cow numbers and milk...

Sorghum (Sorghum bicolor (L.) Moench) pericarp pigments can affect grain quality. Pigments found in vegetative parts of the plant and in the peduncle and glumes of flowers (12,44) also may indirectly impact sorghum grain quality. Pigments associated with the “purple wound response” accumulate following mechanical injury, insect feeding, or pathogen invasion (22,31). Grain with nonpigmented peri...

Six ruminally cannulated steers, five Holsteins and one Hereford (250 to 295 kg), were fed 84% forage sorghum silage plus 16% supplement or 50% forage sorghum silage plus concentrate and supplement diets containing either no addition (controls), 1% sodium bicarbonate (NaI-1CO 3 ) or 2% sodium bentonite in a 2 X 3 factorial arrangement of treatments in a 6 • 6 Latin-square experiment with 3-wk p...

that ‘Coastal’ hybrid bermudagrass receiving 670 kg N ha 1 and 153 kg P ha 1 from swine effluent removed Five warm-season annual grasses were compared for dry matter an average of 382 kg N ha 1 yr 1 and 43 kg P ha 1 yr 1. (DM) yield and nutrient uptake alongside bermudagrass [Cynodon dactylon (L.) Pers.] on a Brooksville silty clay (fine, montmorillonitic, Adeli and Varco (2001) found that ‘Ali...

Seedlings of both KS8 and N32 sorghum [Sorghum bicolor (L.) Moench] were high in dhurrin [p-hydroxy-(S)-mandelonitrile-BD-glucoside] and thus in hydrocyanic acid potential (HCN-p), but the HCN-p of mature leaves from field-grown plants of KS8 was only about one-tenth as high as that of N32. A study of the inheritance of this large difference between KS8 and N32 revealed that a single major gene...

Hydrocyanic acid or prussic acid poisoning of livestock by sorghums [Sorghum bicolor (L.)Moenchl and sudangrasses [Sorghum sudanese (Piper) StapfJ is caused by the digestive liberation of hydrocyanic acid (HCN) from the cyanogenic compound, dhurrin [(S)-p-hydroxymandelonitrile ,8-D-glucopyranosideI found in tissue of these plants. Recent research documented that dhurrin is also present in india...

An oxalate oxidase was purified to apparent homogeneity from the leaves of 10-days old seedlings of forage Sorghum (Sorghum vulgare var. KH-105). The enzyme had a Mr of 124 kDa with two identical subunits, an optimum pH of 4.5, optimum temperature of 37 degrees C and activation energy (Ea) of 2.0338 Kcal/mol. The rate of reaction was linear up to 7 min. K(m) value for oxalate was 0.22 mM. The e...

Root segments and root-soil cores (6.5-cm diameter) from fields and nurseries of winter wheat and sorghum were tested for N2 fixation by using the acetylene reduction assay. Wheat samples (approximately 1,200) from 109 sites generally had low or no activity (0 to 3.1 nmol of C2H4 produced per h per g [dry weight] of root segments), even after 24 h of incubation. However, a commercial field of S...

The aim of this study was to evaluate morphophysiological indices, phenology and cutting time forage cactus (Opuntia Nopalea spp.) clones intercropped with sorghum cultivars (Sorghum bicolor). experiment carried out from 2017 2018, in two cropping systems (monocropping intercropping), comprising 12 treatments, consisted three clones: ‘IPA Sertânia’—IPA, ‘Miúda’—Miu ‘Orelha de Elefante Mexicana’...
