“…The use of plant growth-promoting rhizobacteria (PGPRs) can be a promising biological alternative for increasing the rooting of cuttings [13]. Azospirillum is a genus of PGPRs that inhabits the roots of host plants and provides beneficial effects to the plant under normal growth and/or stress conditions [14].…”

Association between auxins and plant growth-promoting bacteria can stimulate root growth and development of fruit crop nursery plants, and can be a promising biological alternative to increase the rooting of cuttings. The objective of this study was to assess the viability of producing ‘Powderblue’ blueberry nursery plants from cuttings using different doses of indolebutyric acid (IBA) in association with Azospirillum brasilense. The following treatments were tested: 0 (control); 500 mg L−1 of IBA; 1000 mg L−1 of IBA; A. brasilense; 500 mg L−1 of IBA + A. brasilense; and 1000 mg L−1 of IBA + A. brasilense. The experimental design was completely randomized, with six treatments and four replicates, and each plot (box) consisted of 10 cuttings. The boxes were arranged in a mist chamber with an intermittent regimen controlled by a timer and solenoid valve. After 90 days, the following variables were assessed: rooted cuttings; survival of cuttings; foliar retention; sprouting; cuttings with callus; root dry mass per cutting; number of roots per cutting; and root length. It was observed that the application of IBA with the A. brasilense rhizobacteria increased the number of roots of ‘Powderblue’ blueberry cuttings, while the treatments with IBA alone and IBA 1000 mg L−1 + A. brasilense increased the root length of cuttings. However, treatments with IBA and A. brasilense had no impact on % rooted cuttings and % survival of cuttings.

“…Embora inoculação de A. brasilense não tenha apresentado resultados satisfatórios neste estudo, outros autores vêm destacando efeitos positivos e potenciais em sua utilização com relação ao enraizamento, bem como de outros organismos considerados rizobactérias promotoras do crescimento de plantas (RPCP). Exemplo disso são os trabalhos desenvolvidos por Erturk et al (2010) e Mariosa et al (2017), onde os autores observaram a produção in vitro de ácido indolacético (IAA), principal auxina endógena sintetizada pelos vegetais, Vivas Mortas por diferentes isolados de RPCP. Quando aplicados com intuito de estimular o enraizamento, os resultados apontam o potencial de uso desses microrganismos e sugerem o desenvolvimento de mais estudos a fim de verificar as possibilidades de produção desses inoculantes de maneira comercial.…”

“…Microrganismos, tais como fungos micorrízicos arbusculares e bactérias diazotróficas, têm chamado a atenção por contribuir com um modelo atual de agricultura sustentável (Ferreira et al 2015;Mariosa et al 2017). Além disto, outros trabalhos têm reportado o papel destes organismos influenciando no desenvolvimento de raízes adventícias e brotos de plantas aéreas (Melo et al 2012;Vogel et al 2014; Abdel-Rahman e El-Naggar 2014).…”

“…Embora sejam poucos os estudos relacionados a utilização de rizobactérias na propagação vegetativa, é importante conhecer o efeito destes organismos especialmente como uma alternativa orgânica aos reguladores vegetais (Mariosa et al 2017;Rosa et al 2018). Assim, o objetivo desse estudo foi avaliar a influência de bactérias promotoras de crescimento (Azospirillum brasilense) e do ácido indolbutírico (IBA) no enraizamento de estacas de Jasminum mesnyi.…”

There are two primary forms of plant propagation: sexual and asexual. In nature, propagation of plants most often involves sexual reproduction, and this form is still used in several species. Over the years, horticulturists have developed asexual propagation methods that use vegetative plant parts. Innovation in plant propagation has supported breeding programs and allowed the production of high-quality nursery plants with the same genetic characteristics of the mother plant, and free of diseases or pests. The purpose of this Special Issue, “Innovation in Propagation of Fruit, Vegetable and Ornamental Plants”, was to present state-of-the-art techniques recently developed by researchers worldwide. The Special Issue has brought together some of the latest research results of new techniques in plant propagation in nine original papers, which deal with a wide range of research activities.
