Breeding Sweet Basil for Chilling Tolerance
نویسندگان
چکیده
Sweet basil (Ocimum basilicum L., Lamiaceae) is a tropical species native to East Africa (Simon et al. 1990; Vieira and Simon 2000, 2006; Vieira et al. 2003). Sweet basil can be damaged in the field by chilling temperatures in spring and fall, and when stored and transported. Temperatures below 5°C lead to significant leaf necrosis and damage has been observed when temperatures drop below 10°C (Lange and Cameron 1997). Chilling causes brown discoloration of interveinal leaf areas, an increase of leaf blade thickening, decrease of plant growth, a reduction of the postharvest shelf life, and deterioration of quality and marketability (Cantwell and Reid 1993; Lange and Cameron 1994). The present study was undertaken to identify and develop chilling tolerant basil.

Assessment of Five Chilling Tolerance Traits and GWAS Mapping in Rice Using the USDA Mini-Core Collection
Rice (Oryza sativa L.) is often exposed to cool temperatures during spring planting in temperate climates. A better understanding of genetic pathways regulating chilling tolerance will enable breeders to develop varieties with improved tolerance during germination and young seedling stages. To dissect chilling tolerance, five assays were developed; one assay for the germination stage, one assay...

To evaluate the effect of nitrogen sources on yield and quality of sweet basil and forage maize under intercropping (additive series), a field experiment was carried out at the experimental field of faculty of agriculture, Lorestan University, Khorramabad, Iran, in 2013-2014 and 2014-2015 growing seasons. Experimental treatments were arranged as factorial in randomized complete block design wit...

The goal of this study was to identify cold-tolerant genotypes within two species of Miscanthus related to the exceptionally chilling-tolerant C4 biomass crop accession: M. ×giganteus 'Illinois' (Mxg) as well as in other Mxg genotypes. The ratio of leaf elongation at 10 °C/5 °C to that at 25 °C/25 °C was used to identify initially the 13 most promising Miscanthus genotypes out of 51 studied. Ne...
متن کاملChilling Injury of Sweet Potato Shoots Reduced by Prior Incubation of H2O2 and NaCl
Excised shoot tips of sweet potato (Ipomoea babatas L.) were incubated in H2O2 or NaCl aqueous solution for 24h or 48h prior to a 3-day chilling at 2.5°C. Severity of chilling injury was visually observed during a post-chilling 7-day recovery at 21°C, and scored at 0 to 5 (none to most severe injury). In the first experiment, when cv. Purple (PUR) sweet potato shoots were subjected to 3-day chi...
