in this study, a set of experiments were conducted to investigate the influence of edta-grafted iron oxide nanoparticles exposure on agronomic traits of sunflower (helianthus annuus) plants. the experiment was implemented by applying nano-fe3o4-edta and fe-edta fertilizers applied through spray or soil amendment. a variety of parameters including aerial organ biomass, number of leaves, plant he...

In vitro micropropagation is already a current multiplication tool for walnut self-rooted cultivars and rootstocks, but grafting still performed in the field or greenhouses, mainly using seedlings as rootstocks. The present work describes new approach to obtain clonal walnut-grafted plants, involving shoot production of ‘Paradox’ (Juglans hindsi × Juglans regia) cl. ’Vlach’, be used rootstock, ...

The BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) scale is a system that helps producers monitor phenology by employing uniform methodology across different locations. This study aimed to evaluate the effect of scion×rootstock combinations on tomato yield and accumulated degree days for each phenological stage. A randomized block design with four repetitions treatmen...

Recently, we showed that microRNA399s (miR399s) control inorganic phosphate (Pi) homeostasis by regulating the expression of PHO2 encoding a ubiquitin-conjugating E2 enzyme 24. Arabidopsis (Arabidopsis thaliana) plants overexpressing miR399 or the pho2 mutant overaccumulate Pi in shoots. The association of Pi translocation and coexpression of miR399s and PHO2 in vascular tissues suggests their ...

poly n-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. in this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 kgy) under appropriate temperature and grafting conditions was investigated. the ftir analysis showed the existence of the graft pnipaam on the substrate. the optimal value of the dose for grafting was ...

Aim of this study was to investigate the influence two methods grafting on Passiflora gibertti in antioxidant capacity. Experiment conducted under field conditions agricultural years 2012/2013 and 2013/2014 following a randomized block design, being studied three treatments, plants not grafted, grafted by cleft laterally with maintenance root system. Fruit were harvested when they physiological...

Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well Embrapa’s new hybrid, BRS Acará, were evaluated rootstocks for the bell pepper Margarita (Syngenta) Pampa (Clause) scions, under natural infestation of Ralstonia pseudosolanacearum, upon artificial inoculation with a) ten isolates, b) one Phytopht...
