Maturity group (based on the number of days to maturity) is an important growth trait for determining crop productivity, but there has been no attempt to examine the effects of elevated [CO(2)] on yield enhancement of rice cultivars with different maturity groups. Since early-maturing cultivars generally show higher plant N concentration than late-maturing cultivars, it is hypothesized that [CO...

With the objective to identify previously unknown parental relationships among grapevine cultivars, 352 cultivars of Vitis vinifera L. were analyzed at 17 microsatellite loci. 29 were found to be duplicate genotypes of other cultivars. From the 323 unique genotypes, 89 possible pairs of parents were identified for 52 cultivars (i.e., each putative progeny cultivar shared at least one allele wit...

Silver nanoparticles (AgNp) have been widely developed, one of which is an antibacterial agent. The ability AgNp to inhibit bacteria unquestionable. These properties and characteristics can be studied further by adding defects. defect used Cdots from tangerines. are new materials that synthesized natural unique properties. itself was the chemical reduction method with sodium citrate as a reduci...

We used native polyacrylamide gel electrophoresis to identify polymorphism levels in α- and β-esterase loci from leaf tissues of Brazilian soybean cultivars for the analysis of population genetic diversity and structure, and to investigate relationships between conventional and genetically modified cultivars. The cultivars included lines developed by a soybean-grower cooperative (CD), by ...

Acytogenetic study was performed on 66 tetraploid cotton cultivars (Gossypium hirsutum L.) and their hybrids. The cultivars studied differed significantly in their chiasma frequency and distribution as well as chromosome pairing indicating their genetic differences. Adjacent and alternate quadrivalents were formed in most of the cultivars. A-A or D-D heterozygote translocations occurred in most...

A replicated field study was conducted from 1972 to 1980 involving soybeans grown in 2-, 3-, and 4-year rotations with maize in soil infested with Meloidogyne incognita. Monocultured soybeans were maintained as controls. Cropping regimes involved root-knot nematode susceptible and resistant soybean cultivars and soybeans treated and not treated with nematicides. Yields of susceptible cultivars ...

Reasons for the variable amylose content of endosperm starch from waxy cultivars of barley (Hordeum vulgare) were investigated. The mature grains of most such cultivars contain some amylose, although amounts are much lower than in wild-type cultivars. In these low-amylose cultivars, amylose synthesis starts relatively late in grain development. Starch granules in the outer cell layers of the en...

Soybean (Glycine max) producers in Ohio rarely use soybean cyst nematode (Heterodera glycines, SCN)-resistant cultivars because of concerns over limited yield potential and lack of resistance to Phytophthora sojae. A two-year study was initiated to determine grain yield and nematode population increase on soybean cyst nematode-resistant cultivars in maturity groups II and III in production fiel...

Date palm is an important crop, especially in the hot-arid regions of the world. Date palm fruits have high nutritional and therapeutic value and possess significant antibacterial and antifungal properties. In this study, we performed bioactivity analyses and metabolic profiling of date fruits of 12 cultivars from Saudi Arabia to assess their nutritional value. Our results showed that the date ...

The genetic diversity of Saudi locally growing sorghum (Sorghum bicolor) cultivars has not been thoroughly characterized. To understand the genomic patterns of diversification in Saudi sorghum cultivars (N = 7), random amplified polymorphic DNA (RAPD) was used as a rapid, inexpensive method for providing information regarding genomic variability below the species level. Six commercially availab...
