What Are the Benefits of High-Density Orchards?

The dwarfing rootstocks that increase tree numbers in high-density orchards have a smaller and shallower root system. Several vital root traits like root length density (RLD), lower root number density (RND), and fewer and smaller fine roots are characteristics of dwarfing rootstocks. The root traits in dwarfing rootstocks lower the vegetative vigor but increase flower… Continue reading…

Understanding the Impact of High Temperatures on Crop Roots

Due to climate change-related high temperatures on crop roots, root architecture is altered. Roots change the carbohydrate/amino acid ratio and lipid metabolism to limit growth disruption and activate heat pathways. Temperature-induced hormone changes trigger signals to activate root responses to stress. Roots must also deal with climate change effects like drought, nutrient deficiency, salinity, and… Continue reading…

Climate Change Effects on Plant Development: Comprehensive Insights

Climate change can alter plants’ roots, vegetation, and reproductive development. Climate change effects on plant development can sometimes be similar across species or depend on tissue, species, genotype, and development stage. Plants are most sensitive to temperature and drought stress effects during the reproductive phase. Several features characterize climate change, like higher concentrations of greenhouse… Continue reading…

Understanding Fine Root Dynamics: Key Insights and Methodologies

Fine roots have a diameter of 0.1–2 mm and are essential for nutrient acquisition for individual plants and carbon and nutrient cycling for ecosystems. Research shows fine roots are not a single group; root order determines form, anatomy, physiology, and function. Fine root age is another significant factor that influences functioning and dynamics. Though fine… Continue reading…

Understanding Drought Impact on Crop Yield: Stages, Mechanisms, and Adaptations.

Drought’s impact on crop yield affects plant stages differently, moderated by genotype and external environmental factors. Very early drought can inhibit germination and seedling establishment, reducing stand density and yield. Drought during reproductive and grain filling can reduce yield quantity and quality more than during the growth phases. Drought is the primary environmental stress crop… Continue reading…

How Does the Rhizosphere Effect Influence Plant Growth and Soil Health?

The rhizosphere is the soil surrounding the plant root and soil interface. Root exudates, controlled by plant species, functional type, root traits, and biomes, can determine the biology, physics, and chemistry of the rhizosphere effect. The rhizosphere effect can enhance nutrient availability and defense at the plant level; carbon and nutrient cycling and possible bioremedial… Continue reading…

Advances in the Measurement of Root Turnover with Minirhizotron Technology

Root turnover rates are complex to measure as growth and death co-occur in plants. Minirhizotron is a standard method for estimating root turnover as it is non-destructive, rapid, and accurate. One challenge in the widespread use of minirhizotrons for root turnover is the lack of analysis methods to directly convert root scans to turnover estimation.… Continue reading…

What We Learned About Roots in 2023

Most studies in 2023 focused on root responses to agricultural practices to improve yield using fewer resources. Research into the basic science of roots and the influence of biotic and abiotic factors are the second significant areas of study. Fine roots are a particular area of focus, given their importance in nutrient and water uptake… Continue reading…

Measuring Heat Stress on Forest Trees

The impact of high temperatures directly and alone on trees is significant without the associated drought. Heat effects are recorded at cellular, leaf, and tree levels, inhibiting tree growth and productivity or even mortality. More research is necessary to fully understand the effects of heat stress, which must be supported by on-site, non-destructive data collection… Continue reading…

Minirhizotron Systems for Root Disease Detection

Root diseases are a significant issue in reducing crop yields globally. The damage and symptoms caused by root diseases change morphology and growth dynamics that images and scans can detect. Minirhizotron systems can detect a wide range of root changes reflecting various levels of root disease severity, providing a novel detection method. Root diseases are… Continue reading…
