“…In another study, Hemida et al [45] found an improvement in the soil physiochemical characteristics and productivity of Phaseolus vulgaris with the soil application of 0.5 kg −1 potassium humate and 1.0 mM-α-tocopherol as compared to the control. Baraldi et al [46] found that the higher application of potassium 500 mg kg −1 in an in vitro medium showed a lower root length and root system of golden delicious as compared to the lower rates of potassium humate application (0, 50 and 250 mg L −1 ). The strong and positive correlations were found among the growth, yield and fiber qualities except fiber length (Table 5).…”

Humus is the stable form of added crop and animal residues. The organic matter after a long-term decomposition process converts into humic substances. The naturally occurring humus is present in less amount in soils of the arid and semi-arid regions. The addition of commercially available humic acid can, therefore, contribute to improving soil health and crop yields. The present study was conducted to evaluate the effect of potassium humate, applied through soil seed dressing, on cotton productivity and fiber quality attributes. Seed dressing with potassium humate was done at the rate of 0, 100, 150 and 200 mL kg−1 seed while in soil potassium humate was applied at the rate of 0, 10, 20 and 30 L ha−1. Results showed that the combined application of potassium humate by seed dressing and through soil application improved the soil properties, productivity and fiber quality traits of cotton. All levels of soil applied potassium humate (10, 20 and 30 L ha−1) performed better over seed dressing in terms of cotton productivity and fiber quality attributes. Among the soil application rates, 20 L ha−1 potassium humate proved better as compared to other rates (0, 10 and 30 L ha−1). Higher soil application of potassium humate (30 L ha−1) showed depressing effects on all the traits studied like the reduction of 12.4% and 6.6% in Ginning out turn and fiber length, respectively, at a seeding dressing of 200 mL kg−1. In conclusion, potassium humate seed dressing and soil application at the rate of 200 mL kg−1 and 20 L ha−1, respectively, is a better approach to improve cotton productivity. Soil potassium humate should not exceed a rate of 20 L ha−1 when the seed dressing of potassium is also practiced.

“…The highest proliferation rates were obtained on media supplemented with 5.0 mg l -1 metatopolin or 2.0 mg l -1 BAR, which produced 6.9 and 5.9 shoots per explant, respectively. Explants cultured on media without cytokinin tended to form only one new shoot (on average 1.6 shoots per explant) confirming that cytokinins are necessary for adequate shoot proliferation (Lane, 1978;Sriskandarajah et al, 1990;Baraldi et al, 1991).…”

The in vitro shoot multiplication of apple cv. Jonagold was tested on media containing benzyladenine, benzyladenine riboside or meta-topolin in different concentrations (from 0.0 to 5.0 mg l -1 ). The optimal concentration for the best multiplication varied according to the type of cytokinin. The highest multiplication rate (on average 6.9 and 5.9 new shoots per explant) was achieved using 5.0 mg l -1 metatopolin or 2.0 mg l -1 benzyladenine riboside. The longest shoots were formed on media containing benzyladenine riboside at a concentration of 0.5 mg l -1 . The length of newly developed shoots was strongly suppressed by high concentrations of different cytokinins, but the suppression effect of a high concentration of meta-topolin on shoot length was less than that of benzyladenine or benzyladenine riboside. In this study meta-topolin and benzyladenine riboside proved to be effective cytokinins to induce adequate shoot proliferation, while benzyladenine was the least active cytokinin.

“…Além disso, Baraldi et al (1991), obtiveram a maior taxa de multiplicação (4,8%) quando adicionado humato de potássio na concentração de 50 mg L -1 e 1,0 mg L -1 de 6benzilaminopurina (BAP), no cultivo in vitro de maçã 'Golden delicious'.…”

O mirtileiro (Vaccinium sp.) é uma frutífera bastante apreciada pelos consumidores em virtude de suas propriedades nutracêuticas. Entretanto, ainda há dificuldade na propagação de algumas cultivares, comprometendo assim a expansão da cultura. Dessa forma, se faz necessários estudos direcionados ao aperfeiçoamento no sistema de produção de mudas. Através deste estudo, objetivou-se avaliar o uso de 2iP, bem como concentrações de substâncias húmicas na etapa de multiplicação in vitro da cultivar 'Woodard'. O delineamento experimental foi o inteiramente casualizado, em esquema bifatorial (duas concentrações (0; 100 mg L-1) de 2iP e quatro concentrações (0; 1; 2; 3 mg L-1) de substâncias húmicas), totalizando oito tratamentos e cinco repetições com cinco explantes. Aos 60 dias avaliou-se: sobrevivência, número de folhas, taxa de multiplicação, número de brotações, comprimento da maior brotação, comprimento da parte aérea, massa de matéria fresca e massa seca de parte aérea. Assim, concluiu-se que a multiplicação in vitro de pode ser realizada com o uso de 1 mg L-1 de substâncias húmicas, sem a utilização de 2iP.
