“…In the same way Costa et al (2012) studying Tamarindus indica reported a relationship between substrate and DQI. Contrasting our results Silva et al (2018) did not find significant differences for DQI in Achachairu (Garcinia humilis) seedlings grown in different substrate compositions, the authors attributed this result to the adaptability of the seedlings in high quality substrates.…”

An obstacle to the production of mangosteen seedlings (Garcinia mangostana L.) is the long nursery time of approximately two years. Among other factors, the identification of a suitable substrate for seedling production from this species is a preponderant factor to reduce nursery time. This study aimed to evaluate the growth of seminal mangosteen seedlings grown in four different substrate compositions. Growth rate was determined using the following variables: stem diameter, plant height, stem dry mass, leaf dry mass, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI). The substrate S1 (sphagnum turf and vermiculite) was superior to substrates S2 (pinus bark and vermiculite), S3 (pinus bark and coconut fiber) and S4 (soil) in all evaluated parameters. The principal component analysis separated the treatments into three response groups, in which S1 exerted the greatest influence on the growth variables, concluding that this one of the substrates tested was the most adequate for the formation of mangosteen seedlings. Susbtrato e qualidade de mudas de mangostanzeiroResumo-Um entrave para a produção de mudas do mangostanzeiro (Garcinia mangostana L.) é o prolongado tempo de viveiro de aproximadamente dois anos. Dentre outros fatores, a identificação de um substrato adequado à produção de mudas dessa espécie é fator preponderante para reduzir o tempo de viveiro. Este estudo objetivou avaliar o crescimento de mudas seminais de mangostanzeiro cultivadas em quatro diferentes composições de substrato. A avaliação do crescimento foi realizada por meio das variáveis diâmetro do coleto, altura das plantas, número de folhas, área foliar, matéria seca do caule, matéria seca da folha, matéria seca da parte aérea, matéria seca da raiz, matéria seca total e Índice de Qualidade de Dickson (IQD). O substrato S1 (turfa de sphagnum e vermiculita) foi superior aos substratos S2 (casca de pínus e vermiculita), S3 (casca de pínus e fibra de coco) e S4 (solo) em todos os parâmetros avaliados. A análise de componentes principais separou os tratamentos em três grupos de resposta, em que o S1 foi o que exerceu maior influência sobre as variáveis de crescimento, concluindo ser este, dentre os substratos testados, o mais adequado para formação de mudas de mangostão.

“…In the production of G. humilis seedlings, Silva et al (2018) compared two production environments with 50 % shading screens and showed that the nursery with aluminized thermal-reflective screen resulted in more vigorous seedlings with a higher dry matter of shoots and roots, when compared to the nursery with black shading screen. Studies with sunlight restriction levels for forest tree species have reported that the 50 % shading level resulted in high-quality seedlings for Schizolobium amazonicum Huber ex Ducke (Gondin et al 2015), Caesalpinia ferrea C. Mart.…”

“…Materials from organic or mineral sources are easy to acquire and have a good porosity to provide physicochemical properties essential to the requirements of each species. According to Silva et al (2018), the use of substrate based on the mixture of cattle manure, soil, vermiculite and sand is adequate to produce G. humilis seedlings.…”

The successful establishment of a Garcinia humilis orchard depends on planting high-quality seedlings. This study aimed to evaluate the effects of the shading level (0 %, 18 % and 50 %) and substrate composition on the formation of G. humilis seedlings. Four substrates (S) were evaluated combining different proportions (v:v) of soil (SO), cattle manure (CM), commercial substrate (CS), sand (SA) and fine grain vermiculite (FV): S1 = 0 % SO + 45 % CM + 20 % CS + 20 % SA + 15 % FV; S2 = 15 % SO + 30 % CM + 20 % CS + 20 % SA + 15 % FV; S3 = 30 % SO + 15 % CM + 20 % CS + 20 % SA + 15 % FV; S4 = 45 % SO + 0 % CM + 20 % CS + 20 % SA + 15 % FV. The experiment was conducted in a completely randomized design in each environment, being the environments compared by a joint analysis. The G. humilis seedlings with the highest quality were obtained in the environment with a 50 % shading screen. G. humilis seedlings do not grow when exposed to full sunlight and, therefore, the seedling production of this species with direct solar radiation, without some shading level, should not be recommended. Different combinations from the mixture of soil, cattle manure, commercial substrate, sand and fine grain vermiculite may be used in the formulation of substrates for G. humilis seedlings.

“…The production of seedlings in protected environments can improve the quality and sanity of the plants due to the improvement of environmental conditions such as temperature, humidity, and light intensity during all seasons of the year. Silva et al (2018) studied the initial growth of achachairu seedlings (Garcinia humilis Vahl.) in two production environments with 50% shading, showed that nursery with aluminized thermal-reflective screen produced better quality seedlings when compared to the nursery with black shading screen.…”

The successful establishment of a forest restoration program depends of the seedling quality, and the choice of substrate and growing environment plays a significant role in the production of high-quality seedlings. A study was conducted to evaluate the production of croada seedlings (Mouriri elliptica Mart.) grown in thirteen substrate combinations and subjected to two production nurseries constructed with black shading screen (Sombrite®) and aluminized thermal-reflective screen (Aluminet®). The substrates were prepared from different proportions of bovine manure, soil, vermiculite, and sand. In each protected environment, the thirteen different substrate compositions were arranged in a completely randomized design with five replicates of the five seedlings each. Because there was no replication of the cultivation environments, the joint analysis was carried out, allowing the comparison of the environments in the factorial scheme 2 × 13 (two environments × thirteen substrates). Growth and quality of seedlings were measured at 188 days. Seedling production environment has no effect on the germination and emergence process of the seedlings, but the growth and quality of the seedlings can be improved when grown in the nursery with black shading screen. Substrates containing low proportion of bovine manure (from 10 to 30%) and high proportion of vermiculite (from 30 to 40%) resulted in high-quality croada seedlings.
