Seedling vigor in tomatoes determines the quality and growth of fruits and total plant productivity. It is well known that the salient effects of environmental stresses appear on the internode length; the length between adjoining main stem node (henceforth called node). In this study, we develop a method for internode length estimation using image processing technology. The proposed method cons...

The objective of this work was to evaluate the losses in process, survival, uniformity and growth during an entire short rotation a clonal planting Eucalyptus grandis x urophylla Brazil as function different morphological characteristics seedlings considered proxy seedling quality. Seedlings were classified descending order quality by following treatments: A > B C. Treatment D composed prime...

Citrus species are among the most important fruit crops. However, gene regulation and signaling pathways related to etiolation in this crop remain unknown. Using Illumina sequencing technology, modification of global gene expression in two hybrid citrus cultivars-Huangguogan and Shiranuhi, respectively-were investigated. More than 834.16 million clean reads and 125.12 Gb of RNA-seq data were ob...

Abstract The creation of highly productive forests should be based on the use high quality seedlings. Those machines and technologies that have been used for cleaning subsequent sorting coniferous seeds with their sowing in nursery do not fully provide forestry complex good-quality planting material. reason this is unsorted fractions nurseries, failure to observe conditions during ensure amicab...

Eastern black walnut (Juglans nigra L.) has potential for agroforestry practices in the eastern United States because of its value for nuts and timber; however, practices for optimum nut production are poorly defined. Studies were conducted to determine the type of planting material that can assure successful establishment of black walnut for nut production. The first study compared the surviva...

Morphological quality of black walnut (Juglans nigra L.) seedlings largely dictates their capacity to establish well in plantations and their performance potential for use as rootstocks in grafting. Larger seedlings and rootstocks, attained from propagation at relatively low nursery sowing densities, have comparatively more expansive root systems for exploitation of soil resources and greater n...

A method combining solid-phase extraction and reversed-phase high-performance liquid chromatography is described for the isolation of two key metabolites in the limonoid biosynthetic pathway critical to citrus quality. Potassium salts of limonoate A-ring lactone and nomilinoate A-ring lactone were isolated from young Chandler pummelo seedlings and characterized on the basis of proton and carbon...

Seedling quality is an important input affecting the outplanted seedling performance. Morphological attributes and association with symbiotic ectomycorrhizal (ECM) fungi belong to influential traits determining quality. In this study, effect of pre-sowing applied commercial additives Ectovit (containing hydrogel ECM fungi), Mycorrhizaroots (ECM nutrients) Vetozen (natural mineral fertilizer) on...
