“…It was verified that the seedlings grown on the Bioplant ® substrate obtained a larger stem diameter, where a mean diameter of 1.08 mm was verified. According to Freitas et al (2013) in a study of the production of seedlings grown on substrate with humic acid, it was verified that the Bioplant ® substrate demonstrated efficiency in the development of guava plants. These authors also observed that the sand substrate, although being well used in the seed germination process, does not present colloidal or nutrient properties, and it is necessary to add other organic sources to obtain superior results in both germination and plant development.…”

The guava (Psidium guajava L., Myrtaceae) is originates of Tropical America and is distributed throughout the Brazilian territory. The seedling production stage is very important because seedlings of higher quality have a direct influence on success and final production. Therefore, it is necessary to use substrates with good nutritional quality to supply the nutrient demand of the crop. In this way, the objective of this study was to evaluate the germination of 'Cortibel' guava seeds and initial development of the plants in different substrates. The seeds were obtained in physiologically mature fruits and sown in 1.5 L bags with two types of substrate (sand and commercial substrate Bioplant ®). The design was completely randomized, two substrates were the treatments with nine replicates and each repetition with five bags, totaling 45 experimental units for each treatment. Germination was monitored for 129 days. The characteristics of plant height, stem diameter and number of leaves were evaluated. The substrate sand provided a higher germination rate in relation to the Bioplant ® substrate, however, the use of commercial substratum presented a higher initial development, with higher values of plant height and stem diameter, which is indicated for the production of seedlings of guava 'Cortibel' by seeds due to the presence of nutrients in its composition.

“…According to Freitas et al (2013) The degree of success of the propagation will depend on the interaction between these factors, the possibility of manipulation and the knowledge of each specie needs. For , the environmental variations and the characteristics of each season of the year are factors that can cause variation in the production of buds in the mini-stumps and rooting of the minicuttings.…”

“…The use of clonal mini-gardens for the production of mini-cuttings is being used in several crops, such as guava (Freitas et al, 2013), 'pitangueira' (Peña et al, 2015), blueberries (Affonso et al, 2015) and forestry species such as Cedrela fissilis (Xavier et al, 2003), Toona ciliata (Souza et al, 2014) and Paulownia fortunei (Stuepp et al, 2015).…”

Productivity and rooting of olive mini-cuttings grown in a clonal mini-garden according to season

et al. 2018

The mini-cuttings productivity in clonal mini-garden using the semi-hydroponic system is a promising technique for the olive propagation, to obtaining a satisfactory amount of cuttings and with good quality. The objective was to evaluate the mini-stumps productivity and rooting of olive mini-cuttings in successive collections at different times of year in a clonal mini-garden in a semi-hydroponic system. In each collection the productivity of the clonal mini-garden was evaluated counting the collected cuttings. The mini-cuttings were prepared with 3-5 cm long with leaf area reduced by 50% and placed in plastic boxes with vermiculite for a period of 80 days. The evaluated variables were: mini-stumps productivity, mini-stumps and mini-cuttings percentage of survival, rooting percentage and number and length of mini-cuttings root. The olive mini-cuttings presented higher productivity during the spring of 2014. The mini-cuttings rooting percentage collected during the evaluated periods demonstrated that mini-cutting is a viable technique for olive propagation when grown in clonal mini-garden using a semi-hydroponic system.

“…As miniestacas são obtidas de minitouceiras, e estudos recentes têm apontado a miniestaquia como técnica promissora para produção de mudas de goiabeiras, possibilitando ganhos no enraizamento de cultivares menos propensas a emitir raízes adventícias, como é o caso da 'Cortibel 6', pertencente a um grupo de variedades cultivadas no Espírito Santo (FREITAS et al, 2013).…”
