“…The rapid increase in the stem diameter of the rootstock is desirable since this variable is directly related to the moment when the rootstock is ready for grafting (Souza et al, 2018b). Working under similar conditions to the present study, Souza et al (2017) obtained rootstocks of the Capdeboscq and Okinawa cultivars with stem diameters of 7.14 and 6.23 mm, respectively, at 154 days after sowing. According to Menegatti et al (2019c), growing conditions and genotype can influence the number of days to reach the grafting stage after planting the rootstock.…”

“…Considering seedling production in plastic bags or other types of containers, knowledge of the effects of fertilizer doses and frequency is important, as there can be intense nutrient leaching due to constant irrigation in protected environments, and due to the small dimensions of the containers, as well as plant stress associated with high salt concentrations (Souza et al, 2018). Due to their potential effects on plant growth, nitrogen fertilizers should be applied judiciously during the seedling production process to achieve the best productive performance (Menegatti et al, 2019a).…”

The objective was to evaluate whether the different levels of fertilization with Ca(NO3)2 influenced the growth of rootstocks cultivated in packaging. The plant material used in the experiment was obtained from seeds produced by mother plants of the rootstock cultivar Tsukuba 1, and from two intraspecific F1 hybrids of Prunus persica, derived from reciprocal crossing, selections being NR 0080412 ('Capdeboscq' x ' Flordaguard') and NR 0280401 ('Flordaguard' x 'Capdeboscq'), all with purple leaves. The experimental design was completely randomized, in a 3 x 5 factorial scheme, with three genotypes and five different doses of nitrogen, in the form of calcium nitrate. Five replications were used for each treatment, with the experimental unit consisting of one plant. It was verified that the highest dose of Ca(NO3)2, provided the best quality of the seedlings, which was expressed in the highest DQI, for the three genotypes evaluated, highlighting the seedlings of the 'NR 0080412' selection, which also proved to be more vigorous in relation to the other evaluated genotypes.

“…The soil in the orchard is moderately deep, with an average texture in the A horizon and a clayey texture in the B horizon, and is classified as a typic dystrophic Red-Yellow Argisol (Souza et al, 2017c). The mean cold accumulation in the region, below 7.2 °C, is around 400 hours, the mean annual rainfall is 1,367 mm, and the mean annual minimum and maximum temperatures are 13.8 °C and 22.9 °C respectively (EAP, 2018).…”

The aim of the present study was to carry out a search for phytonematodes to verify the abundance and frequency of nematodes present in a peach orchard at eight years of age. Soil and root samples from nine peach rootstocks were collected in an experimental area in the district of Capão do Leão, in the State of Rio Grande do Sul, Brazil. After extraction, the samples were evaluated under an optical microscope. Nematodes of the following genera were identified in the samples: Meloidogyne spp., Pratylenchus spp., Helicotylenchus spp., Mesocriconema spp., Trichodorus spp., Longydorus spp., Tylenchorchynchus spp., Hemiciclyophora spp., Xiphinema spp., Tylenchulus spp., Dorylaimus spp., Rotylenchulus spp. and Mononchus spp., all associated with the roots or soil rhizosphere of ‘Aldrighi’, ‘Capdeboscq’, ‘Flordaguard’, ‘Nemaguard’, ‘Okinawa’, ‘Tusukuba’, ‘Umezeiro’, ‘Viamão’ and ‘Industry’ rootstocks. The most frequent phytoparasitic nematodes were Meloidogyne spp., and Mesocriconema spp., which, under high populations or under inadequate management of the cultivated area, represent a risk to peach cultivation. Xiphinema and Pratylenchus are two other phytonematodes that can cause damage to peach trees and were identified in greater abundance in the ‘Industry’, ‘Viamão’ and ‘Nemaguard’ rootstocks. Under the conditions of the present research the ‘Okinawa’ and ‘Umezeiro’ rootstocks proved to be unfavourable hosts, especially for Meloidogyne spp. and Mesocriconema spp. The ‘Viamão’, ‘Capdeboscq’, ‘Aldrighi’ and particularly the ‘Industry’ rootstcks should not be recommended for use in areas with an incidence of the nematodes Meloidogyne spp. or Mesocriconema spp.

“…The DQI is a quality parameter initially developed for forest species [38] that is now widely used as a quality, vigour, and yield potential indicator for a broad range of species [15,39]. However, few studies have described plant quality using this index for fruit [40][41][42][43] and ornamental [24] species and for herbaceous crops, including aromatic species and horticultural crops [44]. Therefore, the objectives of this study were to conduct a review and bibliometric analysis of the application potential of the DQI as a main parameter for assessing plant quality during plant production, as well as in relation to other scientific applications of this index.…”

Plant quality and survival prediction tools are useful when applied in the field in different agricultural sectors. The objectives of this study were to conduct a review and bibliometric analysis of the Dickson Quality Index (DQI) as a key plant quality indicator and with respect to its scientific applications. A third objective was to identify the main morphological and physiological parameters used in plant production research. The methodology and findings of 289 scientific articles were analysed based on the morphological, physiological, and mathematical parameters used as plant quality indicators in research on forest, medicinal, horticultural, aromatic, and ornamental species. During the last 10 years, the number of publications that have used the DQI as a plant quality parameter has increased by 150%, and Brazilian researchers stand out as the most frequent users. Forestry is the discipline where quality parameters and their biometric relationships are most often used to facilitate intensive plant production. Use of the DQI increases the certainty of prediction, selection, and productivity in the plant production chain. The DQI is a robust tool with scientific application and great potential for use in the preselection of plants with high quality standards among a wide range of plant species.
