Clonal propagation of fruits, flowers, and forest trees leads to high levels of heterozygosity, fixes favorable combinations of traits, eliminates undesirable deleterious effects, allows easy identification, propagation of favorable mutations, and is an efficient method for in vitro and ex vitro ...

Shoot-tips 15cm long from 15 soybean cultivars and breeding lines were individually immersed in Hoagland's solution in 1 × 14 cm test tubes, and supported by cotton plugs. All leaves were removed leaving about 1 cm of each petiole on the shoot. A 4 mm mycelial plug of Sclerotium rolfsii Sacc., ta...

The starchy staples of cassava (tuberous roots) provides more than half the calories consumed by more than 200 million people in sub-Saharan Africa, and the leaves are often used as a vegetable providing protein, vitamins and minerals. The cyanogenic potential of cassava has often been cited as a...

An in vitro growth system was used to determine the virulence of two samples of Striga gesnerioides from Zakpota in southern Benin. Cowpea variety B301, previously considered resistant to all races of S. gesnerioides, was susceptible to both samples of the parasite. Two other cowpea varieties, 58...
