Abstract:

Modern truffle cultivation is based on use of inoculated seedlings, which should exhibit highly colonised roots as well as a vegetative quality enhancing field plant performance. However, poor shoot and fine root growth has been a frequent issue in inoculated <em>Quercus</em> seedlings production. Fertilisation is a common solution in forest nurseries, but high fertilisation levels have been found to inhibit the formation of ectomycorrhizas of many fungal species. The influence of slow-release fertilisation (52 mg N, 26 mg P and 36 mg K per seedling) on growth and ectomycorrhizal sta

Abstract:

The seed accelerated ageing test is one of the most important tests for testing seed vigour, which provides the determination of the degree of preservation for germination and the determination of the duration of the seed storage. The aim of this study was to observe effects of two different production methods (organic and conventional) on seed vigour of soybean cultivar Kaca, by the application of the seed accelerated ageing test. The seeds were exposed to stress conditions for 72 h (temperature of 45?C and air humidity of 100%). After the test was applied, the number of non-germinated seeds

Minimizing environmental stress in bedding plant and greenhouse and seedling development has occupied many researchers in academia and industry for many years. The dependence on single plant germination units (plugs) for bedding plant production and high value hybrid seed demand high rates of germination and successful seedling establishment. Pre-germinating or priming of seed is an important method of germination enhancement and methods and benefits of “priming” will be discussed. Environmental options to enhance seed germination of non-primed seed include control of vapor pressure deficit (V

Production and use of doubled haploids (DH) is becoming an essential part of maize breeding programs worldwide as DH lines offer several advantages in line development and evaluation.

This step of artificially doubling the chromosomes is labor-intensive and costly; hence, optimizing protocols to improve the doubling success is critical for achieving efficiencies in the DH production pipeline

Abstract:

This paper reports on a new graphical analysis technique that facilitates screening alternative strategies for crop management in programs of integrated vegetation management in young forest plantations. The responsiveness of black spruce seedlings to three vegetation management measures (herbicide application, fertilization and seedling nutrient loading) on two contrasting site types (Hardwood [ST 10] and Feathermoss [ST 4]) located in northern Ontario, were compared and evaluated using vector competition analysis. The approach is based on vector diagnosis and regression analysis that compare

(1) Background: In recent years, the use of light emitting diodes (LEDs) for plant production purposes has expanded. However, LEDs’ effect on seed germination and early seedling growth has been scarcely documented. (2) Methods: In this work, the effect of monochromatic red light (RL, 100 µmol m−2 s−1) for up to 60 min applied to seeds of pea and melon was analyzed in terms of seedling growth and antioxidant enzymes levels. An experimental LED chamber coupled to an electronic control system was developed for this purpose. (3) Results: RL did not alter the germination rate, but significantly imp

Abstract:

Initiation, development, and subsequent growth of seedling root and shoot components can have a direct influence on the quality, adaptation, and survival of seedlings, particularly under stress conditions. Taproot, basal, lateral, and adventitious root components (common indicot plants) each have their own development sequence, growth rate, and may have separate functions for subsequent seedling growth and development. Stresses originating in root components may be expressed in shoots affecting dry matter partitioning between roots and shoots. Partitioning and development of root morphological

Abstract:

To characterize the adaptability of strip tillage for wheat production in a rice–wheat rotation system in China, a two-year experiment was conducted. Three methods of tillage and sowing were designed, including broadcast and drill sowing following full tillage (TS1 and TS2) as well as drill sowing following strip tillage (TS3), under two planting densities. Compared to TS2, TS1 only increased seedling tiller number (by 17%–54%) at the beginning of the over-wintering stage, while TS3 improved tiller number, leaf area, and shoot weight (by 17%–39%, 14%–15%, and 19%–27%, respectively), achieving

Abstract:

The article presents the results of research on optimizing the methods of intensification of growing seed rootstocks based on common quince of VNIISPK breeding in a nursery. In the course of the research, it has been found that the highest yield of seed rootstocks with optimal economic and biological characteristics is provided by sowing germinated seeds in late April. Seeds should be sown in artificial beds according to the scheme of 0.5 cm x 20 cm, which will allow to obtain a high yield of seedlings of good quality and increase the efficiency of growing seed rootstocks.

Abstract:

Assessing the quality of maize seedlings is crucial for field management and germplasm evaluation. Traditional methods for evaluating seedling quality mainly rely on manual field surveys, which are not only inefficient but also highly subjective, while large-scale satellite detection often lacks sufficient accuracy. To address these issues, this study proposes an innovative approach that combines the YOLO v8 object detection algorithm with Voronoi spatial analysis to rapidly evaluate maize seedling quality based on high-resolution drone imagery. The YOLO v8 model provides the maize coordinates
