ABSTRACT Organic residue in the substrate and availability of light influence production high-quality seedlings for ex situ cultivation native forest species. This study aimed to evaluate effect doses chicken manure incorporated soil shading levels on morphophysiological responses quality Alibertia edulis (Rich.) A. Rich seedlings. Five (CM) were tested, 0.00, 2.08, 4.16, 6.24, 8.32 g CM kg-1 s...

Protein hydrolysates are widely used in agricultural crops for improving plant nutrient uptake, growth, yield, and fruit quality. Tomato (Lycopersicon esculentum Mill.) is one of the most important vegetables consumed around world both its good taste rich content vitamins, minerals, lycopene, β-carotene. The objective present study was to assess effect new stimulant products based on protein ob...

Light-emitting diodes (LEDs) have been regarded as the best artificial source of light for a plant factory. However, effect quality on seedling production in such environments requires further study. On basis practical application cucumber seedlings (Ansha Company) factories, present investigation tracked and recorded specific effects red blue growth by analyzing photo-biological mechanism invo...

Developing seedlings of the Arabidopsis gun1 (genomes uncoupled1) mutant, which is defective in retrograde plastid-to-nucleus signalling, show several previously unrecognized mutant phenotypes. gun1 seedlings accumulated less anthocyanin than wild-type seedlings when grown in the presence of 2% (w/v) sucrose, due to lower amounts of transcripts of early anthocyanin biosynthesis genes in gun1. N...

BACKGROUND AND AIMS Crop yield and nutritional quality are significantly reduced when potassium (K) in soil is deficient. As a beneficial element for plants, silicon (Si) is effective in alleviating the toxic effects of mineral nutrients. However, the roles played by Si in mediating deficiency in essential mineral nutrients in general and K in particular have not been investigated. METHODS To...

The objectives were to determine the physical and chemical characteristics of different substrates, assess influence with without addition controlled-release fertilizer, on growth morphological quality taperebá (Spondias macrocarpa) seedlings. experimental design adopted was a 2 x 6 factorial scheme, presence absence 8.0 g L-1 encapsulated fertilizer six substrates [Sub1= soil; Sub2= soil + car...
