“…Diameter is an important predictor of survival and growth in the field, as it is a proxy indicator for the size of the root system [50]. Plants with a larger stem diameter tend to survive better than small stem diameter seedlings, which is why it is considered the most useful morphological measure of seedling quality [51].…”

Rooting substrate and fertilization are key components in the production of containerized seedlings, as they can influence the morphological and physiological characteristics of the plants, which in turn can impact outplanting performance. The objective of the study was to evaluate the effect of four substrates based on mixtures of peat moss (PM), composted bark (CB) and raw pine sawdust (PS), combined with two doses of controlled release fertilizer (CRF) and one non-fertilized control, on the growth of Pinus cembroides Zucc. in the nursery. The treatments were: M1: 50+25+25, M2: 25+25+50, M3: 25+50+25 and M4: 50+50+0 of PM+ CB+ PS (% by volume), respectively. Fertilizer treatments used a controlled release fertilizer (Multicote®): F1: 3 kg m−3 and F2: 6 kg m−3 and a control (WF: with no added fertilizer). The treatments were distributed in a randomized complete block design, with a factorial arrangement of 4 × 3 and six replications. The variables evaluated were: height, seedling diameter, dry biomass, Dickson Quality Index, N, P and K content. Regardless of the substrate, the high fertilizer dose (6 kg m−3) improved most morphological variables. In addition, the high fertilizer dose resulted in foliar N, P and K concentrations within recommended ranges for all substrates. The substrate containing only peat moss and composted bark (M4 + F1 and M4 + F2) had the best growth response. However, the substrate composed of 25% peat moss, 50% composted bark and 25% raw pine sawdust with the high fertilizer dose (M3 + F2) resulted in acceptable seedling growth, and may be preferred if the cost of the substrate is a concern to nursery manager.

“…While RCD is positively and significantly correlated with both survival and growth after seedlings planting at the field, seedlings height can have both, positive and negative effect on seedlings field survival and growth, as reviewed by Ivetić and Devetaković [50]. Their combination as the HD (height/RCD) ratio was the most reliable plant attribute to forecast Austrian pine seedlings field performance [4] and there is evidence that initial seedling height and RCD are equally related to the field performance [3]. Our results show a consistent effect of seed colour on seedlings field growth of height and RCD.…”

“…The success of forest establishment program, including afforestation, reforestation, and forest restoration [1,2] mainly depends on the quality of Forest Reproductive Material (FRM), i.e., seedlings [3,4] and seeds [5]. FRM is often subjected to transfer and trade [6,7], emphasizing the genetic component of FRM quality regarding the seed source [8] and genetic diversity of seed lot used for production of seedlings in nursery or for direct seeding on the field [9].…”

Research Highlights: One of the ways to improve the quality of a seedlot used in the forest nursery is the grading of seed by colour. Background and Objectives: The study is intended for forest’s engineers and owners because it offers an alternative solution for forest seeds improvement before sowing. The success of forest establishment program mainly depends on the quality of Forest Reproductive Material. At this time usual practices during the seed processing is seed grading on size. This causes a lot of controversy about the possible reduction of genetic diversity through directional selection. Materials and Methods: Aiming to study the effect of seed coat colour on seedling performance, a one-year old container seedlings of Pinus sylvestris L. were planted at the post-fire site. Seedlings were produced from three fractions, previously graded in the visible wavelength range on a standard optical separator, plus control obtained without separation by colour. Results: Seedlings from different seed fractions performed differently in the first growing season after planting on the field. Seedlings from light seed fraction grow better in height, but those from dark seed fraction resulted with the highest survival rate. Light-dark seeds, which constitute the largest group in the initial sample by absolute weight, resulted with seedlings of the lowest growth rates and survival. The good results showed by seedlings from the control, for both growth rates and survival, indicate the weak effect of seed colour grading on seedlings field performance, but also the need for the more comprehensive studies in the future.

“…Since the spring of 2018, each month during the first growing season in the field, a seedlings height from the root collar to the apical bud was measured with an accuracy of 1 mm (see Table 1). Although the seedlings diameter is usually recognized as the single most reliable quality attribute [35,36], the seedlings height is useful in forecasting their growth and survival in the field [37,38].…”

Seed coat color grading conjecture is also known as Pravdin's conjecture. To verify the conjecture, we established a long-term field experiment. This data set included unique empirical data of Scots pine (Pinus sylvestris L.) container-grown seedlings produced from different seed color grades, outplanted on a post fire site in the Voronezh region, Russia. Variables were provided for 10 rows of 90 samples in each row. These data contribute to our understanding of seed germination and seedlings growth dynamics from size and color gradings of seeds. This structure is the future basis of the Forest Reproductive Material Library (FRMLib) and will be used for assisted migration and forest seed transfer.Dataset: Dataset access at http://dx.
