Effect of Root-Zone Temperature on Growth and Quality of Hydroponically Grown Red Leaf Lettuce (Lactuca sativa L. cv. Red Wave)
Soil temperature influences crop growth and quality under field and greenhouse conditions; however, precise investigation using controlled cultivation systems is largely lacking. We investigated effects of root-zone temperatures on growth and components of hydroponically grown red leaf lettuce (Lactuca sativa L. cv. Red Wave) under a controlled cultivation system at 20 ̊C. Compared with ambient ...
متن کاملIntegrated Effects of Root-Zone Temperatures and Phosphorus Levels on Aeroponically-Grown Lettuce (Lactuca sativa L.) in the Tropics
In this study, butterhead lettuce (Lactuca sativa L. cv. Baby Butter) plants were grown at three root-zone temperatures (RZTs): 25 o C, 30 o C and ambient-RZT (A-RZT) ranging from 26 o C-42 o C while their shoots were maintained at hot ambient temperature ranging from 26 o C-42 o C. Three phosphorus (P) concentrations: -25% P (minus P, 23.25ppm), control (31.00ppm) and +25% P (plus P, 38.75ppm)...
متن کاملeffect of carbon dioxide injection to root zone on the growth and nitrate accumulation in two cultivars of lettuce (lactuca sativa l. cv. capitata and sativa)
nitrate is an essential component for plants and vegetables are of the most important source of nitrate for human being. it is estimated that vegetables provide 92 % of nitrate for human nutrition. the positive and negative effects of elevated root zone co2 on growth and yield of some plants have been reported. this study has been conducted in order to examine the effect of root zone co2 on gro...
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...
متن کاملRoot exudation and root development of lettuce (Lactuca sativa L. cv. Tizian) as affected by different soils
Development and activity of plant roots exhibit high adaptive variability. Although it is well-documented, that physicochemical soil properties can strongly influence root morphology and root exudation, particularly under field conditions, a comparative assessment is complicated by the impact of additional factors, such as climate and cropping history. To overcome these limitations, in this stu...
