1 INTRODUCTION 1.1 Plant biomechanics and lodging-resistance. The failure of crop plants to maintain a vertical position is referred to as lodging and can affect both crop yield and grain quality (Berry et al., 2004; Fedenko et al., 2015; Rajkumara, 2008).Plant lodging occurs due to weak stalk and/or failed root anchorage, and multiple factors contribute to lodging susceptibility.

Mechanical Support STILT ROOTS: - These roots normally arise from a few lower nodes of a weak stem in some monocots, shrubs and small trees. - They grow obliquely downwards and penetrate the soil and provide mechanical support to the plant. - In plants like maize, sugarcane, bajra and jowar, the roots grow in whorls.
Breeding for crop plants with deeper root systems and stronger anchorage to the soil will greatly favor the development of mechanical control technologies (Kurstjens et al. 2004). The selection of ...
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water.
In general, anchorage failure is a universal danger for small plants attached to soft sediments but declines rapidly as sediment strength increases, particularly for larger plants. The model predicts that Myriophyllum is the least susceptible of the four species to anchorage failure and consequently the most likely to break ( Fig. 5 ).
Answer (1 of 4): Cytoskeleton is a stable and dynamic proteins that gives the cell shape, structure, and mechanical resistance to deformations. It is extended throughout cytoplasm. All cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Micro...
Chapter 7 – Getting to Know Plants consists of answers to the questions related to each and every topic present in this chapter. In this chapter, we shall deal with concepts related to different functions of a plant. Students can refer to NCERT Exemplar Class 6 Science solutions which is the best reference material any student can rely on.
Plant cells have a cell wall, chloroplasts, and a central vacuole. The plant cell wall, whose primary component is cellulose, protects the cell, provides structural support, and gives shape to the cell. Photosynthesis takes place in chloroplasts. The central vacuole expands, enlarging the cell without the need to produce more cytoplasm.
Plant Parts and Their Functions – Structural Organization in Plants. The Root. The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis of plant growth regulators.
Anchorage: root systems extend outward and/or downward through soil, thereby stabilizing plants. Oxygen: the spaces among soil particles contain air that provides oxygen, which living cells (including root cells) use to break down sugars and release the energy needed to live and grow.
Cereal crops are faced with a complex mechanical challenge: they must be rigid enough to support their own weight, but flexible enough to be resilient in the face of external forces (e.g., wind) (Gardiner et al., 2016).Mechanical failure of cereal crops is known as lodging (see Box 1 for a glossary of terms used in this article) and refers to the "permanent displacement of plants from their ...

This review provides an overview of field-based mechanical testing approaches to assess stalk and root lodging resistance. These approaches are placed in the context of future perspectives. Best practices and recommendations for acquiring field-based mechanical phenotypes of plants are also presented.
An anchorage is a location at sea where ships can lower anchors. Anchorages are where anchors are lowered and utilised, whereas moorings usually are tethering to buoys or something similar. The locations usually have conditions for safe anchorage in protection from weather conditions, and other hazards. What provides anchorage to plant?

The method presented in this study uses measured plant anchorage forces to quantify crop and weed sensitivity to being uprooted by a weed harrow and predicts the relationship between weed and crop uprooting by mechanical weeding. Uprooting and anchorage force of young perennial ryegrass and garden cress plants were measured in laboratory ...

mechanical harvesting of peppers requires es-tablishing complementary horticultural prac-tices. One such practice is using beds and soil hilled to the base of the plants. Hilling soil to the base of the plants provides structural sup-port and increases anchorage, which helps to reduce plant uprooting during mechanical har-vesting (Marshall, 1984).
balance between investment in anchorage and in breakage resistance is needed to survive in the fluctuating physical environment of lakes. 6 Pulling forces experienced by aquatic plants are distinct from the mainly bending forces on more rigid land plants. We provide the first theoretical and quantitative framework for understanding their effects.

tribute to plant stability by forming rigid elements in the root system, e.g. deep taproots, or by forming a rigid root–soil plate. Tree anchorage may also be related to various architectural root characteristics. Mechanical stress may cause an increase of total root cross sectional area (CSA) (Crook and Ennos, 1996; Mickovski and Ennos ...

Mechanical failure, known as lodging, negatively impacts yield and grain quality in crops. Limiting crop loss from lodging requires an understanding of the plant traits that contribute to lodging-resistance. In maize, specialized aerial brace roots are reported to reduce root lodging. However, their direct contribution to plant biomechanics has not been measured.
Therefore, mechanical stability requires that the root–soil system provides a restoring moment (M R) that equals the bending moment (M R =M B); that is, anchorage failure may occur when M R
