Effects 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 کاملInduction of Light Sensitive Dormancy in Seed of Lactuca sativa L. (Lettuce) by Patulin.
The antibiotic patiilin (I) has been reported to inhibit seed germination becauise of its toxicity (7). We considered that this butenolide (I) might induce light sensitive dormancy in seeds of lettuce because of its structural similarity to coumarin (II) and ramulosin (III), (see fig 1), which have been demonstrated to possess this biological activity (2,5,6). Possible activitv was tested in th...
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...
متن کاملSystematic silencing of a tobacco nitrate reductase transgene in lettuce (Lactuca sativa L.).
A population of 50 independent transgenic lettuces transformed with a nitrate reductase coding sequence under the control of the 35S promoter was studied. None of them showed significantly lower nitrate levels when compared with the untransformed plants, despite the presence of nitrate reductase (NR) activity that derives from the transgene in at least four of the transformants. No repercussion...
متن کاملGrowth and Yield of Lettuce (Lactuca sativa L.) At Abakaliki Agro-Ecological Zone of Southeastern Nigeria
Studies were carried out in 2005 and 2006 raing seasons at four locations (Abakaliki, Ezzamgbo, Ikwo and Okposi) within the Abakaliki Agro-ecological zone of southeastern Nigeria, to determine their suitability for the production of lettuce. The measurements included weather elements, soil physico-chemical propertiesand crop growth and yield. The data collected were subjected to statistical ana...
