Salt Tolerance of Glycinebetaine-Deficient and -Containing Maize Lines

Ability to Remove Na+ and Retain K+ Correlates with Salt Tolerance in Two Maize Inbred Lines Seedlings

Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Here, excellent salt-tolerant maize inbred line TL1317 and extremely salt-sensitive maize inbred line SL1303 were screened to understand the maize response to salt stress and its tolerance mechanisms. Relative water content, membrane stability index, stomatal conductance, chlo...

Salt tolerance of sunflower varieties during germination

Exogenous application of glycinebetaine increases chilling tolerance in tomato plants.

Tomato (Lycopersicon esculentum Mill. cv. Moneymaker) plants are chilling sensitive, and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant. We reported previously that exogenous GB application enhanced chilling tolerance in tomato. To understand its protective role better, we have further evaluated various parameters associated with improved tol...

Salt Tolerance and Salt Poisoning of Swine

COMMON SALT is recognized as one of the chemical substances required in the diet of animals; hence it is good husbandry to include a supply in the rations of livestock. The quantitative requirements vary with the species. Those for swine are regarded as among the lowest. That excessive aniounts may be harmful to the extent of being toxic is not at all surprising, since there are recognized limi...

Flooding tolerance in interspecific introgression lines containing chromosome segments from teosinte (Zea nicaraguensis) in maize (Zea mays subsp. mays).

BACKGROUND AND AIMS Nicaraguan teosinte (Zea nicaraguensis), a species found in frequently flooded areas, provides useful germplasm for breeding flooding-tolerant maize (Z. mays subsp. mays). The objective of this study was to select flooding-tolerant lines using a library of introgression lines (ILs), each containing a chromosome segment from Z. nicaraguensis in the maize inbred line Mi29. M...
