Plant roots sense soil compaction through restricted ethylene diffusion [PDF]

Science, 2021
Ethylene aplenty signals soil compaction It's tough to drive a spade through compacted soil, and plant roots seem to have the same problem when growing in compacted ground. Pandey et al. found that the problem is not, however, one of physical resistance but rather inhibition

Effect of Lycium barbarum L. Root Restriction Cultivation Method on Plant Growth and Soil Bacterial Community Abundance

Agronomy, 2022
The root restriction of protected cultivation has been widely used to increase productivity and sustainability in modern agriculture. However, there have been few studies of wolfberry (Lycium barbarum) root restriction, and it is cultivated mostly by ...

Root-shoot growth and time to transplant of different lettuce genotypes during nursery

Revista de la Facultad de Ciencias Agrarias, 2021
Although vegetable nursery growers decide on plug sizes based on the types, production time and schedule of the crops to grow, they usually choose individual small cell sizes because these allow short plant-raising periods and reduced costs. However,

Effects of Comparative Metabolism on Tomato Fruit Quality under Different Levels of Root Restriction

HortScience, 2023
In a soilless culture (perlite substrate), root restriction cannot only reduce production costs but also improve fruit quality. Therefore, this study used different levels of root restriction [T1: 0.5 L, T2: 4 L, nonrestriction treatment (CK): 35 L] on ...

Environmental and Cultivation Factors Affect the Morphology, Architecture and Performance of Root Systems in Soilless Grown Plants

Horticulturae, 2021
Soilless culture systems are currently one of the fastest-growing sectors in horticulture. The plant roots are confined into a specific rootzone and are exposed to environmental changes and cultivation factors.

Brassinosteroid signaling restricts root lignification by antagonizing SHORT-ROOT function in Arabidopsis

Plant Physiology, 2022
Abstract Cell wall lignification is a key step in forming functional endodermis and protoxylem (PX) in plant roots. Lignified casparian strips (CS) in endodermis and tracheary elements of PX are essential for selective absorption and transport of water and nutrients. Although multiple key regulators of CS and PX have been identified, the

Destackification with restricted root operations [PDF]

European Journal of Mathematics, 2018
Let \(X\) be a smooth separated Deligne-Mumford stack of finite type over a field \(k\). The stack \(X\) is assumed to be \textit{tame}, i.e., \(\text{char}(k)\) does not divide the order of the stabilizer group at any geometric point of \(X\) which is equivalent to that \(X\) has the étale local structure over its coarse moduli space of a quotient ...

The Effects of Root-zone Restriction on Water Consumption and Fruit Quality of Greenhouse Muskmelon under Mulched Drip Irrigation

Guan'gai paishui xuebao, 2021
【Background】 Improvement in living standard has shifted the demand of people for foods from quantity to quality. Given that roots not only anchor crops but also take up nutrients from soil to sustain crops growth, it has been conjectured that managing ...

Cadmium-induced lignification restricts soybean root growth

Ecotoxicology and Environmental Safety, 2010
The effects of cadmium (Cd), a well-known environmental pollutant with high toxicity to plants, were tested on root growth, cell viability, phenylalanine ammonia-lyase (PAL) soluble plus cell wall-bound peroxidase (POD) activities, hydrogen peroxide (H(2)O(2)) levels, and the content and monomeric composition of lignin in soybean (Glycine max) roots ...

Restriction method for approximating cube roots

Innovative Journal of Mathematics (IJM), 2022
The aim of this paper is to present a new method called "Restriction Method for Approximating Cube Roots", that helps students to find an approximate value for any cube root of any rational number with an easy and simple way. Also, we prove this method and we give some examples that enhance our method.
