“…This trend was also observed by Zonta et al (2009), in coffee seedlings, when the increase in irrigation interval reduced the growth in diameter and height. Carvalho et al (2013), in yellow passion fruit seedlings, and Tsukamoto Filho et al (2013), in seedlings of Myracrodruon urundeuva Fr. All of them observed that the growth in stem diameter, height and number of leaves decreased when irrigation frequency changed from daily to alternating, and these results can be associated with the water stress that may occur as the intervals between irrigations increase.…”

The objective of this work was to evaluate the growth of sugar-apple seedlings under irrigation management with saline water in a substrate with soil amendment. Treatments were obtained from the arrangement between polymer doses (0, 0.2, 0.6, 1.0 and 1.2 g dm-3) and levels of irrigation water electrical conductivity (0.3, 1.1, 2.7, 4.3 and 5.0 dS m-1), associated with irrigation frequencies (daily and every alternate day), and two additional treatments to evaluate container volume (1.30 and 0.75 dm3), using a randomized complete block design, with four replicates. At 120 days after sowing, the variables substrate salinity, stem diameter, plant height, number of leaves and Dickson quality index were determined. Data were submitted to analyses of variance, regression and contrast. Substrate salinity increased with the increase in irrigation water electrical conductivity and polymer doses. Growth and quality of the seedlings were reduced with increasing irrigation water salinity, and highest values of the variables were obtained in seedlings under daily irrigation. Container with larger volume led to higher growth. The use of hydrated polymer at the adopted levels had no effect on growth and quality of seedlings, requiring further studies. To produce sugar-apple seedlings with better quality, irrigation frequency should be daily and water electrical conductivity should be lower than 2 dS m-1.

“…As to the Dickson Quality Index (DQI), none of the treatments evaluated resulted in values equal to the minimum mean (0.20), being the highest DQI referring to the substrate constituted by carnauba residue (0.17). However, it should be emphasized that this minimum mean refers to the Pseudotsuga menziessi and Picea abies species and may not be appropriate to the species in the present study, according to Tsukamoto Filho et al (2013) information in the literature on an adequate DQI related to most forest species is scarce. There was a significant different between the classes of soils for all variables shown in Table 6.…”

“…Freitas et al (2017) described the same, considering that various parameters allow nursery manegers to better choose seedlings that will perform better after planting. Tsukamoto-Filho et al (2013) and Lopes et al (2014) also refer to the management practices needed for plantations maintenance and related costs. In addition, a high quality seedling means hight timber production capacity, which is described in Silveira et al (2013) and Faria et al (2013) as the main goal of any forest company in the world.…”

The seedlings production process of forest plant species is found to be an important stage in the forest-based production chain. The present work was conducted in commercial nurseries aiming to assess morphological parameters of Eucalyptus clonal seedlings in the expedition phase. The experiment was performed in two nurseries located in the southern part (Nursery #1) and slopes' field (Nursery #2) of the State of Minas Gerais, Brazil. The Completely Randomized Design was used, with four treatments or clones (AEC 144 -Eucalyptus urophylla, AEC 244 -Eucalyptus urophylla, AEC 1528 -hybrid of E. urophylla x Eucalyptus grandis and AEC 100 -hybrid of E. urophylla x E. grandis), seven replications and 16 seedlings per plot. Seedlings were produced in 54 cm 3 tubetes according to nurseries protocols. The following parameters were assessed: plant height, collar diameter, dry matter, and seedlings quality index. The Sisvar statistical analysis system was run for Analysis of Variance, and averages were compared by means of Scott-Knott test at 5% significance. The clone AEC 1528 showed better quality standards at the Nursery #1, and clones AEC 100 and AEC 244 showed greater height and collar diameter at the Nursery #2. Therefore, seedlings from commercial nurseries under study showed adequate morphological quality standards for expedition and planting.
