“…This corroborates the results of Pereira et al (2019) also in rubber tree seedlings of the GT1 clone, with apical pruning treatments. In testing substrates for GT1, PR255, and RRIM600 clones, Vieira et al (2016) obtained the same proportion, whereas Silva et al (2020) reported 34% in roots and 66% in shoot. Our findings show that the use of reflective material provides robust root systems, improving quality of seedlings and their settling in the field.…”

“…Some studies have shown production of better rubber tree rootstocks clone G1 by using 50% shading screen (Sombrite® and Aluminet®) when compared to direct sunlight (Vieira et al, 2016). In turn, when covered with low-density polyethylene, agricultural greenhouses have shown better results than the former mentioned screens (Silva et al, 2020).…”

Success in production of any perennial tree depends on the use of high-quality seedlings. This study aimed to evaluate cultivation benches with reflective material and protected environments for production of rubber tree rootstock seedlings. The experiments were conducted in two types of protected environments: 35% shading aluminized screen and 30% shading black screen. Cultivation benches with and without reflective material were tested inside the protected environments. A completely randomized design with 7 replications and 5 seedlings per plot was adopted for each environment, and the environments were compared by joint analysis. Solar radiation (global and photosynthetically active) was the most influencing micrometeorological factor on plant environment and plant growth differentiation. Regardless of the environment, the use of reflective material in cultivation bench had a positive effect on production of rubber rootstock seedling (clone GT1), providing seedlings with a robust root system and better quality. The use of reflective material also improved rubber tree rootstock seedlings (clone GT1) grown in the black screen environment.

“…Esse foi obtido com a aplicação foliar de bioestimulante. Valores adequados de RMS devem variar de 1 a 2, ou seja, uma distribuição equilibrada (1/1) até no máximo o dobro (Carneiro, 1995;Silva et al, 2020). Mudas com RMS acima dos valores ideais indicam que a parte aérea é bem mais desenvolvida do que o sistema radicular.…”

Objetivou-se avaliar o crescimento e qualidade de mudas de Schizolobium amazonicum (Huber ex Ducke) sob tratamento pré-germinativo de semente e aplicação foliar de agentes químicos durante a formação. O experimento foi realizado realizados no laboratório de análises de sementes e casa de vegetação da Universidade Estadual de Mato Grosso do Sul/Unidade Universitária de Cassilândia-MS. Utilizou-se o delineamento inteiramente casualizado, em esquema fatorial 2x3, sendo constituído por dois tratamentos pré-germinativos por hidratação das sementes (TS1 – água e TS2 – nitrato de cálcio 0,2%) e três agentes químicos fornecidos via foliar (TF1 – testemunha sem tratamento, TF2 – Bioestimulante composto por giberelina 0,1% + auxina 0,2% + nitrato de cálcio 0,2% e TF3 – mistura contendo paclobutrazol 0,01% + uréia 0,2%) com 10 repetições por tratamento e 6 plantas por repetição. Aos 45 dias foi realizada as primeiras medições e a avaliação final foi realizada aos 60 dias (período de plantio das mudas no campo). O tratamento de sementes com nitrato de cálcio produziu mudas com qualidade semelhante as mudas originadas de sementes que foram hidratadas somente com água. O uso de paclobutrazol e nitrogênio na aplicação foliar resultou em mudas de eleva a qualidade de Schizolobium amazonicum.

The rubber tree (Hevea brasiliensis) is an important forest species that yields natural rubber. Traditionally, rubber tree grafts are cultivated in clonal gardens on soil, which necessitates enormous acreage. However, this approach is not only inefficient in terms of productivity, but it also has nutritional and water control constraints. A tiny clonal garden with a balanced fertilizer treatment is an approach that has previously been employed for other species. To apply this same system to the rubber tree, the goal was to investigate the effects of applying macro and micronutrients via fertigation on the productivity of a mini rubber tree clonal garden, as well as to assess the efficacy of using green stems produced under these conditions in three grafting techniques. Five dosages of macro and micronutrients were administered to grafted rubber tree seedlings (clone ‘RRIM 600’ on ‘GT1’) before transplanting them into plastic pots. A totally randomized design was adopted, with five treatments and ten replications, each with two plants per pot, for a total of twenty plants per treatment. The shoot apex was cut after 105 days, and the green stems measuring more than 20 cm were harvested throughout the course of a year. The number of stems was highest in the months of January to March 2014, after 135 days, reaching 3 green stems per plant-1 per month-1, and productivity increased up to an estimated electrical conductivity of 1.64 mS cm-1. Nutrition was found to boost the output of the rubber tree clonal mini garden as well as the survival of grafts after grafting. The tiny clonal garden is a potential method for getting more vegetative rubber tree propagules.
