Special Issue Information

Dear Colleagues,

Industrialization has been developing rapidly in China, leading to serious pollution in the ecological environment. Forests play an irreplaceable role in meeting people’s needs and improving the living environment. Forest seedlings are the basic materials for forest cultivation, that is, tree planting. Ensuring that a sufficient quantity of seedlings is used and that their quality is high plays an important role in guaranteeing the success of forestry construction and land greening. With global warming and the deterioration of the ecological environment, the study of tree seedling quality improvement has attracted wide attention. However, for many tree species, the mechanisms of seed dormancy and germination, as well as seedling nutrient accumulation, transportation, and allocation, remain unclear. Furthermore, climate change and soil environments have significant impacts on seed germination and seedling growth. The aim of this Special Issue is to bring together successful case studies, lessons learned, and experiences on the following:

(1) Forest tree seeds: seed provenance and its effect on seedling quality; seed development; seed storage methods and physiology; techniques for breaking seed dormancy; mechanisms of seed dormancy and germination; anatomical structures of tree seeds.

(2) Forest tree seedlings: seedling growth characteristics and seedling management of bare-rooted seedlings, container seedlings, vegetative-propagated seedlings and transplanting; factors affecting seedling growth; cutting, grafting, and tissue-culturing techniques for forest tree seedlings; seedling nutrient allocation; seedling irrigation thresholds; seedling storage; seedling quality assessment; stress resistance in seedlings.

(3) Others: nursery soil and pest management (involving water management, weed management, and fertilizer management); effects of soil environments, including fertility, pH, microorganisms, etc., on tree seeds and seedlings.

Chinese fir (Cunninghamia lanceolata) is an important fast-growing tree species for timber production and ecological protection in China. Yet, its tissue culture for seedling propagation is hampered by low proliferation and poor quality. Light quality is vital for seedling proliferation and growth, but the regulatory mechanisms remain poorly understood. In this study, a transcriptome and metabolome were integrated to explore light quality’s effects on adventitious shoot proliferation of tissue-cultured Chinese fir seedlings. The seedlings were grown under red, green, blue, and composite light-emitting diode conditions, with white light as the control. Results showed that blue and blue-dominant composite light enhanced proliferation by promoting auxin and cytokinin and increased biomass. Red light promoted shoot height, leaf area, and carotenoid content due to elevated gibberellin and reduced auxins and cytokinin levels but inhibited proliferation due to hormonal imbalances. Green light increased abscisic acid levels and suppressed growth. Transcriptome and metabolome analyses identified key pathways including plant hormone signal transduction, photosynthesis, and flavonoid and carotenoid biosynthesis. Weighted gene co-expression network analysis (WGCNA) identified four key genes regulated by light quality that further modulated hormone biosynthesis and signaling transduction. This research provided insights for optimizing Chinese fir seedling proliferation and growth, contributing to sustainable plantation management. Full article

Forest plantations represent an alternative to reduce timber extraction pressure in the Amazonian forests. In order to tolerate the hostile field conditions of deforested areas, high-quality seedlings are required. This study aimed to find the optimal dose of a native microbial consortium (NMC), which enhances seedling quality indicators, in three forest species at nursery phase. A completely randomized design (3 × 5) was used. Factor 1: Bolaina blanca (Guazuma crinita Mart.), Capirona (Calycophyllum spruceanum Benth. Hook. f.), and Marupa (Simarouba amara Aubl.). Factor 2: Incremental doses of 0, 160, 320, 480, and 640 mL NMC per plant. The nursery survival (%), robustness index, root height/length ratio, shoot–root index, Dickson Quality Index (DQI), Nitrogen (%), Phosphorus (%), and Potassium (%) content in tissues were analyzed. Statistical analyses consisted of two-way ANOVA per variable and correlation analysis. The results indicated that increasing doses of NMC did not improve nursery survival for any species; did not decrease the robustness index, plant height/root length ratio, or the shoot–root index for any species; and did not increase the DQI, P%, or K% for any species; however, they did increase the N% for all species. In conclusion, the incremental dose of 160 mL was chosen for increasing the N% without affecting nursery survival. Full article
