Semi-High Throughput Screening for Potential Drought-tolerance in Lettuce (Lactuca sativa) Germplasm Collections.
This protocol describes a method by which a large collection of the leafy green vegetable lettuce (Lactuca sativa L.) germplasm was screened for likely drought-tolerance traits. Fresh water availability for agricultural use is a growing concern across the United States as well as many regions of the world. Short-term drought events along with regulatory intervention in the regulation of water a...
متن کاملThe Effect of Cutflower-Rose Waste Biochar on Morphological Traits and Heavy Metals in Lettuce (Lactuca sativa L. cv. Syaho)
Biochar reduces the bioavailability of a wide range of pollutants, especially heavy metals (HMs).To evaluate the effects of waste biochar of cutflower rose on growth characteristics and accumulation of lead (Pb) and cadmium (Cd) HMs of in lettuce, a factorial experiment, based on completely randomized design, with four replications was conducted. The amount of rose biochar at 3 levels (0, 5 and...
متن کاملA Genetic Map of Lettuce (Lactuca sativa L.) with Restriction Fragment Length Polymorphism, Isozyme, Disease Resistance and Morphological Markers.
A detailed linkage map of lettuce was constructed using 53 genetic markers including 41 restriction fragment length polymorphism (RFLP) loci, five downy mildew resistance genes, four isozyme loci and three morphological markers. The genetic markers were distributed into nine linkage groups and cover 404 cM which may be 25-30% of the lettuce genome. The majority (31 of 34) of the RFLP probes det...
متن کاملEffects of Nitrogen Fertilizers on the Growth and Nitrate Content of Lettuce (Lactuca sativa L.)
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer i...
متن کاملInflorescence Development and the Role of LsFT in Regulating Bolting in Lettuce (Lactuca sativa L.)
Lettuce (Lactuca sativa L.) is one of the most important leafy vegetable that is consumed during its vegetative growth. The transition from vegetative to reproductive growth is induced by high temperature, which has significant economic effect on lettuce production. However, the progression of floral transition and the molecular regulation of bolting are largely unknown. Here we morphologically...
