rootstocks effect on plant nutrition concentration in different organ of grafted watermelon

Agricultural Sciences 2013年第5期4卷 230-237页

In this study carried out in 2009 and 2010 growing seasons, effect of rootstocks on plant nutrition partitioning in grafted watermelon onto four gourd rootstocks was investigated. Ferro, RS841 (Cucurbita maxima x C. moschata) and Argentario and Macis (Lagenaria hybrid) were used as rootstocks. Crimson Tide and Crisby watermelon cultivars were used as scion. Grafted and ungrafted seedlings were produced by a commercial seedling company. Plants were grafted by one cotyledon grafting techniques. Experiment was conducted in Alata Horticultural Research Station inMersin. The grafted plants were planted under low tunnel in early spring and regular cultural practices for watermelon were applied. Plant nutrition concentrations were determined in leaf, fruit rind, fruit flesh and seeds. Leaf sample was taken at flowering stage, rind, flesh and seed sample were taken from fully mature fruit. Nitrogen concentration was determined by modified Kjheldahl methods. Phosphorous concentration was determined by vanadomolybdophosphoric acid method. K, Ca, Mg, Fe, Mn, Zn and Cu concentration of samples were determined by atomic absorption spectrophotometry. Plant nutrient concentration in leaf, rind, flesh and seed were significantly affected by rootstocks. Increase in concentration of N, P, K, Ca and Mg in leaves was not observed in grafted plant. Ungrafted plant had higher concentration of Fe, Mn, Zn and Cu in their leaves. Ca concentration in rind of fruits from grafted watermelon was higher than ungrafted control plant except Crimson Tide/Macis and Crimson Tide/Argentario graft combinations. Plant nutrition content of fruit flesh was significantly affected by rootstocks and scion. Magnesium, Fe, Zn and Mn concentration of seed was not significantly influenced by rootstocks and scion while other plant nutrient content was significantly affected rootstocks and scion.

A Phenotyping Protocol for Detailed Evaluation of Apple Root Resistance Responses Utilizing Tissue Culture Micropropagated Apple Plants

引用

American Journal of Plant Sciences 2018年第11期9卷 2183-2204页

In the post-genomics era, reliable phenotypes are considered the bottleneck for unraveling the genetic control over the biology of interest. Phenotyping resistance response of roots to infection by soilborne pathogen is more challenging compared to that of plant aerial parts. In additional to the hidden nature and small stature of fine roots where infection occurs, extra obstacles exist for rosaceae tree crops such as apple. Due to self-incompatible reproduction and high-level heterozygosity of apple genome, genetically identical apple plants cannot be produced through apple seed germination. Here we report an established phenotyping protocol which includes a streamlined tissue culture procedure for micropropagation of uniform apple plants, standardized inoculation procedure using Pythium ultimum, and multilayered evaluating methods on apple root resistance traits. Because of the implementation of tissue culture based micropropagation procedure, constant availability of the uniform plants with defined genetic background, equivalent age and non-contaminated roots overcame a longstanding barrier of systematic and detailed phenotypic characterization of apple root resistance traits. Repeated infection assays by root-dipping inoculation demonstrated the reproducible and wide-range plant survival rates, from single-digit to over 90% survived plants for a given genotype. Genotype-specific values due to P. ultimum inoculation on shoot and root biomass reduction, maximum root lengths, leaf number and cumulative leaf areas were quantified between mock-inoculated and P. ultimum infected plants. Use of a glass-box container offered enhanced accessibility and minimized invasiveness for continuous and non-disruptive observation on the necrosis progression patterns along inoculated roots. With the assistance of a dissecting microscope, the genotype-specific resistance responses along the infected apple roots were captured and analyzed in detail. This reported phenotyping protocol
