Impact of micronutrient seed priming on germination,growth, development,nutritional status and yield aspects of plants     

Sananda Mondal  Bandana Bose 《Journal of plant nutrition》2013,36(19):2577-2599

The present review article is dealing with the potentiality of micronutrients in terms of seed priming treatment and its effect within the plant system is considered. Since last 3 to 4 decades various scientists are working with different planting methods and introduced several seed invigoration techniques, one of them is seed priming. Seed priming is basically a restricted hydration treatment with appropriate timing, in which seeds are treated with various types of organic and inorganic compounds. Whereas in this review, we have discussed the potential of different micronutrients in seed priming treatments for escalating crop growth, development and grain yield. Micronutrient priming has several beneficial effects in the morpho-physiological, biochemical and molecular aspects of the plants. In most cases, micronutrient application through seed treatment has astonishingly performed better than other application methods. Being an easy and cost effective method of micronutrient application, seed priming offer an attractive option for resource-poor farmers.  相似文献   

Influence of indigenous inputs on the properties of old alluvial soil in a mustard cropping system     

Tanushree Mondal  Jayanta Kumar Datta  Naba Kumar Mondal 《Archives of Agronomy and Soil Science》2013,59(9):1319-1332

Field experiments were conducted at the Crop Research and Seed Multiplication Farm of Burdwan University, Burdwan, West Bengal, India, to evaluate the influence of integrated nutrient management on soil physicochemical properties in a mustard (Brassica campestris cv. ‘B9’) cropping system. The experiment was conducted during the winter seasons of 2011–2012 and 2012–2013 in old alluvial soil (pH 6–7). Seven different doses of biofertilizers (Azotobacter and phosphate solubilizing bacteria (PSB)), vermicomposts, organic (cow dung), and chemical fertilizers were applied on mustard in both the experimental seasons. The results indicated an improvement in soil quality by increasing soil porosity and water holding capacity significantly, as well as gradual build-up of the soil micronutrient status after harvesting of the crop. Dual applications of biofertilizers and vermicomposts have contributed significantly to higher soil organic matter, available nitrogen (N), phosphorus (P), and potassium (K) contents as well as micronutrient availability of iron (Fe), manganese (Mn), zinc (Zn), and copper (Cu) and subsequently increased the soil health.  相似文献

Effects of different levels of soil salinity on yield attributes,accumulation of nitrogen,and micronutrients in Brassica spp.     

K. Chakraborty  R. K. Sairam  D. Bhaduri 《Journal of plant nutrition》2016,39(7):1026-1037

The present study was conducted to assess the effect of soil salinity on yield attributes as well as nutrient accumulation in different plant parts of seven Brassica cultivars from two different species raised in pot culture experiment with two levels of salinity treatments along with control corresponding to soil electrical conductivity (EC) values of 1.65 (S₀), 4.50 (S₁) and 6.76 (S₂) dS m^?1. The experiment was consisted of twelve replications in a completely randomized design. Imposition of salinity stress affected various yield attributing characters including plant height, which ultimately led to severe yield reduction. However, tolerant cultivars, CS 52 and CS 54 performed better under salt treatment showing lesser yield loss. Salinity stress reduced the nitrogen (N) content in leaves of the Brassica plants, which reflected in decreased seed protein content. Reduced accumulation of iron (Fe), manganese (Mn) and zinc (Zn) was observed in leaf, stem and root at flowering and post-flowering stages, while CS 52 and CS 54 showed less reduction than susceptible cultivars under salinity stress.  相似文献   

Impact of Boron Deficiency on Changes in Biochemical Attributes,Yield, and Seed Reserves in Chickpea     

《Communications in Soil Science and Plant Analysis》2012,43(2):199-206

To determine the effect of boron (B) deficiency on biomass, reproductive yield, metabolism, and alterations in seed reserves of chickpea (Cicer arietinum L.) cv. ‘13.G‐256,’ plants were grown in refined sand until maturity at deficient (0.033 mg L^?1) and adequate (0.33 mg L^?1) B, supplied as boric acid (H₃BO₃). Boron‐deficient plants exhibited visible deficiency symptoms in addition to reduced number of pods and seeds, resulting in lowered biomass and economic yield. Boron deficiency lowered the concentration of B in leaves and seeds, photosynthetic pigments (leaves), Hill reaction activity, starch (in leaves and seeds), and proteins and protein N (in seeds), whereas phenols, sugars (in leaves and seeds), and nonprotein N (in seeds) were elevated. Specific activity of peroxidase (POX) increased in leaves and pod wall and decreased in seeds, while activity of acid phosphate and ribonuclease were stimulated in leaves, seeds, and pod wall in B‐deficient chickpea.  相似文献

IMPROVEMENT OF SCREENING FOR MANGANESE EFFICIENCY BY PRODUCING SEED WITH SIMILAR MANGANESE CONTENT IN DIFFERENT GENOTYPES AND GENETIC STOCKS     

《Journal of plant nutrition》2013,36(12):2803-2815

ABSTRACT

Genetic improvement of manganese efficiency of crops demands a precise bioassay that avoids the confounding effect of seed manganese on the bioassay for the trait, for a proper comparison of the genotypes the seed manganese content must be similar. Variation in seed manganese can be minimized by the addition of manganese to individual seeds to be planted providing the effect of seed manganese content on early growth and development for the chosen genotype has been determined. It was hypothesized that growing the plants as mono-culms in very small pots under subclinical manganese deficiency would limit grain yield and yield attribute among genotypes, resulting in seed with less variation in manganese content across genotypes. The effect on yield and components of soil fertility ranging from University of California (UC) potting mix, fortified with Osmocote, to 100% manganese-deficient calcareous sand from Wangary, South Australia (Psamment) was determined for 20 bread wheat genotypes and breeding lines. It was observed that a mix of 70% UC and 30% Calcareous Wangary sand from South Australia in small pots minimized variation in grain yield and its components (number of tillers, number of seeds/head, weight of seed) and also lowered variation in seed manganese content among wheat genotypes. This was confirmed in pots of 70/30 UC-sand mix for five bread wheat cultivars, Worrakatta, Barunga, Schomburg, Excalibur, and Frame. The pot results from three replicates were compared with field results for the same genotypes grown at five randomly selected wheat-growing areas in South Australia: Paskeville, Geranium, Minnipa, Nunji, and Cummins. The variation in seed manganese content across genotypes was much less in pot grown seed.

Aneuploid stocks (D-genome diosomic substitution lines) normally have highly variable seed size. Production of seed with similar manganese content was only feasible by growing the seed under multiple levels of soil manganese supply and after analysis selecting seeds with similar manganese content among the various manganese treatments. The effect of aneuploidy on seedling vigor, root growth, seed size and agronomic performance has been reported elsewhere. The effect on seed manganese content and the genetic analysis of micronutrient (manganese) efficiency were determined in the current study.  相似文献
