(In)determinacy in Woody Plants: Limits and Opportunities for Timing Growth in a Changing Climate. [PDF]

open access: yesEcol Lett
Tree growth is shaped not only by temperature and water availability, but also by intrinsic developmental programming that constrains when and how long meristems remain active. We use (in)determinacy—the continuum from fixed, preformed seasonal growth to more flexible, ongoing organ production—to predict how species will differ in risk exposure ...

In-Field Observation of Root Growth and Nitrogen Uptake Efficiency of Winter Oilseed Rape

open access: yesAgronomy, 2020
Field trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage.

Quantitative phenotyping of crop roots with spectral electrical impedance tomography: a rhizotron study with optimized measurement design. [PDF]

open access: yesPlant Methods
Background Root systems are key contributors to plant health, resilience, and, ultimately, yield of agricultural crops. To optimize plant performance, phenotyping trials are conducted to breed plants with diverse root traits.

Measuring the Root Length of Peanuts Grown in Rhizotrons Using Computer Vision

open access: yesAnais do XVII Workshop de Visão Computacional (WVC 2021), 2021
Peanut is one of the most grown leguminous crops in the world, but it can suffer during water deficit periods. In this paper, a new method to help monitoring root growth for laboratory experiments with this plant is proposed. By using a new combination of smoothing, thresholding, morphological filtering and skeletonization, our method has achieved a ...

Illustration of the rhizotron device.

open access: yes, 2015
(A) Sampling map showing the 56 samples (in green). The 8 depths are labeled from A to H and the 7 replicates are labeled from 0 to 6. Twenty-four supplemental samples (in gray) were used for soil humidity measurements.

Examining the effects of soil compaction on plant growth and root systems architecture through the development of a simple, lab-based rhizotron system

open access: yes, 2022
Soil compaction concerns have grown as both annual precipitation and machinery weights have increased in many parts of the world. Compact soil is created by the physical degradation of the soil structure by external factors.
