An experiment was conducted to standardize the different mowing height and inorganic nutrients for better establishment of lawn grass Zoysia matrella. The laid out in Factorial randomized block design (FRBD) with 2 replications at Botanical garden, Department Floriculture Landscape Architecture, Tamil Nadu Agricultural University, Coimbatore. Treatments included (1 inch, 1.5 inch 2.5 inch) leve...

the measurement of chlorophyll content of leaf is as an appropriate criterion in breeding programs to increase the rate of leaf photosynthesis. in order to study the relationship between chlorophyll content and seed yield under saline conditions, 41 wheat genotypes were evaluated in two conditions (normal and salinity stress) at the research field of the national salinity research center (nsrc)...

This experiment was conducted to evaluate the effects of normal CO2 level (350ppm) and elevated concentration (700ppm) on growth and competitive ability of millet and soybean against pigweed and lambsquaters. The plants were planted as mono and multicultural to study interand intra-specific competition in the greenhouse. Root and shoot dry weights and chlorophyll value was measured at the end o...

The color of plants depends to a great extent on the conditions of nutrition. Approximately fifty years ago VILLE (7) attempted to determine the proper provision of plants with elements of nutrition by their color from the amount of chlorophyll produced. The pale color of plants may depend on various causes. In some cases it is called forth by an actual reduction of the amount of chlorophyll ow...

Results from an innovative approach to improve remediation in the rhizosphere by encouraging healthy plant growth and thus enhancing microbial activity are reported. The effect of arbuscular mycorrhizal fungi (Am) on remediation efficacy of wheat, mungbean and eggplant grown in soil spiked with polyaromatic hydrocarbons (PAH) was assessed in a pot experiment. The results of this study showed th...

vetiver grass is known to survive under diverse soil and water conditions. in order to test its potential of salinity and aridity tolerance ability, the effect of salinity and aridity stress on the growth of the vetiveria zizanioides was studied by growing plants in arid soils that receiving salinity stress. the experiment was conducted in a greenhouse, arrangement in a completely randomized de...

The effect of low growth temperature on morpho-physiological traits of maize was investigated by the means of a QTL analysis in a segregating F(2:3) population grown under field conditions in Switzerland. Chlorophyll fluorescence parameters, leaf greenness, leaf area, shoot dry weight, and shoot nitrogen content were investigated at the seedling stage for two years. Maize was sown on two dates ...

Despite the numerous studies on the effect of the magnetic field on plants, the exact mechanism of these effects has not yet been determined. The aim of this study was to compare the effect of magnetic field on growth and photosynthetic characteristics of two almond species (Amygdalus scoparia and A. eburnea). For this purpose, 21-day-old almond plants were affected by 10 mT static magnetic fie...

Although the effects of silicon application on enhancing plant salt tolerance have been widely investigated, the underlying mechanism has remained unclear. In this study, seedlings of cucumber, a medium silicon accumulator plant, grown in 0.83 mM silicon solution for 2 weeks were exposed to 65 mM NaCl solution for another 1 week. The dry weight and shoot/root ratio were reduced by salt stress, ...

copper and nickel are an essential micronutrient for plants, playing an important role in maintaining plants' natural metabolism and growth, but in excess both heavy metal are also a proven inhibitor of various physiological functions. in this study maize (zea mays l.) plants grown in hydroponic culture were treated with 0, 50 and 100 μm cuso4 and 0, 100 and 200 μm niso4 . growth parameter...
