Cryopreservation of cassava zygotic embryos and whole seeds in liquid nitrogen
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/83253
Abstract
Cryopreservation in liquid nitrogen of isolated zygotic embryos and whole seeds of cassava have been studied. A simple method is proposed for utilization in germplasm conservation or other related uses. Very high percentage survival values (ca. 97 percent) of zygotic embryos and whole seeds were obtained by both slow and rapid cooling…

Mirid bug outbreaks in multiple crops correlated with wide-scale adoption of Bt cotton in China
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/43861
Abstract
Long-term ecological effects of transgenic Bacillus thuringiensis (Bt) crops on nontarget pests have received limited attention, more so in diverse small holder based cropping systems of the developing world. Field trials conducted over 10 years in northern China show that mirid bugs (Heteroptera: Miridae) have progressively…

Abstract
Rats fed a corn base diet supplemented with dehulled cottonseed kernels which were boiled in a ferrous sulfate solution for 30 min gained as rapidly and required no more feed per unit of gain than those fed a corn-soybean meal diet. Boiling cottonseed kernels…

Genetic study on post-harvest root deterioration in cassava
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/65780
Abstract
Postharvest root deterioration or vascular streaking of cassava clones (accessions and breeding lines) was evaluated with harvests at different ages (8 and 12 mo.), seasons (beginning and end of wet season), and locations (CIAT-Palmira, Carimagua, and Caribia in Colombia) to assess the effect of environmental factors on cassava genotypes. Vascular streaking…

Abstract
A glasshouse experiment was conducted to determine how reduction conditions would affect plant nutrient availability and uptake in a red-yellow latosol (Acrustox). Soil analysis showed that the most important changes were a marked increase in extractable iron and an inhibition of…

Abstract
In the Cerrado region of Brazil conventional soybean monoculture is since the 1980s being replaced by direct seeding mulch-based cropping (DMC) with two crops per year and absence of tillage practices. The objective of this study was to assess the long-term impact of DMC on soil organic…

Abstract
The extent of 5S and 45S ribosomal DNA (rDNA) variation was investigated in wild and domesticated common beans (Phaseolus vulgaris) chosen to represent the known genetic diversity of the species. 5S and 45S rDNA probes were localized on mitotic chromosomes of 37 accessions by fluorescent in situ hybridization (FISH). The…
