Maize (Zea mays L.).
Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...
متن کاملResponses of Seed Germination, Seedling Growth, and Seed Yield Traits to Seed Pretreatment in Maize (Zea mays L.)
A series of seed priming experiments were conducted to test the effects of different pretreatment methods to seed germination, seedling growth, and seed yield traits in maize (Zea mays L.). Results indicated that the seeds primed by gibberellins (GA), NaCl, and polyethylene glycol (PEG) reagents showed a higher imbibitions rate compared to those primed with water. The final germination percenta...
متن کاملCO(2) Compensation Concentration in Maize (Zea mays L.) Genotypes.
Heichel and Musgrave (4, 5) reported photosynthetic rates of maize genotypes ranging from 21 to 85 mg CO2 dmhr-' which were inversely associated with similar large differences in CO2 compensation concentration of from 9 to 25 plll. Since genotypic differences of the magnitude reported by Heichel and Musgrave would be of great value in breeding for increased photosynthetic efficiency, we conduct...
متن کاملMitigation effects of non-enzymatic antioxidants in maize (Zea mays L.) plants under salinity stress
The effects of non-enzymatic antioxidative compounds such as ascorbic acid, thiamine HCl and β-carotene were investigated on salt stressed maize plants. The maize plants were sprayed with 100 mg L of ascorbic acid, thiamine or β-carotene solutions once a week, up to harvesting of plants. The treatment of NaCl was initiated 25 days after sowing by irrigating the plants with 125 mM NaCl solution....
متن کاملBanding Patterns Activity of Antioxidant Enzymes and Physiological Indices in the Maize (Zea mays L.) Genotypes under Water Deficit Stress
Extended Abstract Introduction and Objective: Various environmental stresses, especially water deficit stress have several and major effects on maize growth and production. Drought is one of the abiotic stresses that due to the great variety of rainfall conditions, it is known from Iran as the most important factor limiting the growth and production of crops. Therefore, the effect of water def...
