Growth and development of tomato seedlings in sphagnum peat, vermiculite, and processed rice hull substrates
Tomato (Lycopersicum esculentum ‘Early Girl’) seedling growth was evaluated in substrates containing varying proportions of ground rice hulls. Substrates were formulated containing 0, 30, 60, and 90% ground rice hulls with one-half of the treatments also treated with a surfactant. Seedling growth in two of the ground rice hull-containing substrates was generally similar to the two controls of 9...
متن کاملThe effect of seed priming and culture medium type on germination characteristics and quality of tomato seedlings (Lycopersicon esculentum)
Extended Abstract Introduction: Today, seed priming is widely used to improve seed germination in a wide range of plant species. As a result of seed pre-treatment, several molecular and biochemical changes occur, including increased macromolecule synthesis, enzyme activity and formation of different metabolites. Enzymatic and metabolic activities, synthesis of proteins in quantitative and qual...
متن کاملeffect of different substrates on tomato production in soilless culture
abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...
متن کاملMechanical Conditioning of Tomato Seedlings Improves Transplant Quality without Deleterious Effects on Field Performance
Excessive stem elongation reduces plant survival in the field and hinders mechanical transplanting. Mechanical conditioning is an effective method for reducing stem elongation during transplant production. This investigation examined the conse quences of mechanical conditioning, using brushing and impedance, on subsequent field performance of tomatoes (Lycopersicon esculentum Mill.). Mechanica...
متن کاملComparison of germination and characteristics of desert mustard seedlings in the growth substrates of mineral tailings and habitat soil
Background and objectives: Iron and related mineral industries are one of the important pillars in industrial development. Extraction of iron ore and steel production is not possible without land degradation, and in this processing, in addition to steel, is a large volume of mineral tailings will be produced that, if not properly managed, will be able to pollute soil, air, and water, that can p...
