Growth and nutrition in plants
Research Guide
What is Growth and nutrition in plants?
Growth and nutrition in plants refers to the physiological processes of plant development driven by essential nutrient uptake, including studies on fertilization methods, substrate influences, genetic diversity, soil fertility, and hydroponic systems to optimize seedling quality and crop yield.
This field encompasses 66,226 works on plant nutrition, substrates, and growth optimization. Research examines the influence of different substrates and fertilization methods on seedling quality, crop yield, and soil fertility. It also addresses genetic diversity in passion fruit cultivation and hydroponic systems for plant growth.
Topic Hierarchy
Research Sub-Topics
Potassium Nutrition in Plants
This sub-topic studies K+ uptake transporters, deficiency symptoms, and roles in enzyme activation and osmoregulation. Researchers examine crop yield responses to K fertilization under stress.
Salinity Tolerance Mechanisms
This sub-topic explores ion exclusion, osmotic adjustment, and Na+/H+ antiporters in halophytes and crops. Researchers use physiological and genetic approaches to breed salt-resistant varieties.
Nutrient Use Efficiency
This sub-topic quantifies uptake, utilization, and remobilization efficiencies for N, P, and micronutrients. Researchers develop 15N and 32P tracing methods for breeding efficient genotypes.
Chlorophyll Fluorescence Analysis
This sub-topic applies PAM fluorometry to assess PSII efficiency, stress detection, and photosynthetic performance. Researchers correlate Fv/Fm with yield under field conditions.
Hydroponic Cultivation Systems
This sub-topic optimizes nutrient solutions, root zone oxygenation, and soilless media for high-yield production. Researchers compare NFT, DWC, and aeroponics for various crops.
Why It Matters
Soil salinization causes crop loss worldwide, and understanding salt tolerance mechanisms in halophytes aids in developing resilient crops, as Flowers et al. (1977) outlined cellular and physiological responses in "The Mechanism of Salt Tolerance in Halophytes" with 1937 citations. Potassium enhances plant stress responses, improving crop yield quality under biotic and abiotic stresses, with Wang et al. (2013) demonstrating its role in biochemical processes in "The Critical Role of Potassium in Plant Stress Response" (1705 citations). Nutrient use efficiency addresses deficiencies in agricultural soils from acidity, salinity, and erosion, where Baligar et al. (2001) showed fertilizer additions improve plant health in "NUTRIENT USE EFFICIENCY IN PLANTS" (1174 citations), directly supporting global maize production supplying 365 Kcal/100g as detailed by Ranum et al. (2014).
Reading Guide
Where to Start
"Avaliação do estado nutricional das plantas: princípios e aplicações" by Malavolta et al. (1997), as it provides foundational principles for assessing nutritional status, cited 1999 times, essential before exploring specific tolerances or efficiencies.
Key Papers Explained
Malavolta et al. (1997) in "Avaliação do estado nutricional das plantas: princípios e aplicações" establishes nutritional assessment basics. Flowers et al. (1977) in "The Mechanism of Salt Tolerance in Halophytes" builds on this by detailing salt response mechanisms. Wang et al. (2013) in "The Critical Role of Potassium in Plant Stress Response" extends to nutrient-specific stress roles, while Baligar et al. (2001) in "NUTRIENT USE EFFICIENCY IN PLANTS" integrates efficiency under deficiencies. Baker (2004) in "Applications of chlorophyll fluorescence can improve crop production strategies: an examination of future possibilities" applies monitoring techniques across these contexts.

Advanced Directions
Research continues on salinity impacts, with Munns and Gilliham (2015) in "Salinity tolerance of crops – what is the cost?" quantifying yield costs amid rising salinized land from poor drainage and warming. Nutrient efficiency persists as a focus given 66,226 works, emphasizing substrates and hydroponics for yield optimization.

Frequently Asked Questions
What principles guide the evaluation of plant nutritional status?
Malavolta et al. (1997) detailed principles and applications for assessing plant nutritional status in "Avaliação do estado nutricional das plantas: princípios e aplicações", cited 1999 times. These methods support monitoring nutrient levels to optimize growth. They apply across various crops and conditions.
How do plants tolerate salt stress?
Flowers et al. (1977) described cellular and physiological mechanisms in halophytes responding to salt in "The Mechanism of Salt Tolerance in Halophytes" (1937 citations). Responses occur in time- and tissue-dependent contexts. This reduces crop losses from soil salinization.
What role does potassium play in plant stress response?
Wang et al. (2013) showed potassium affects biochemical and physiological processes influencing growth and metabolism in "The Critical Role of Potassium in Plant Stress Response" (1705 citations). It counters biotic and abiotic factors reducing crop yield. Potassium application improves plant resilience.
How does chlorophyll fluorescence aid crop production?
Baker (2004) reviewed chlorophyll fluorescence parameters linked to photosynthetic performance in "Applications of chlorophyll fluorescence can improve crop production strategies: an examination of future possibilities" (1593 citations). Non-invasive monitoring guides production strategies. It assesses leaf performance effectively.
What limits nutrient use efficiency in plants?
Baligar et al. (2001) identified soil deficiencies from acidity, salinity, and erosion in "NUTRIENT USE EFFICIENCY IN PLANTS" (1174 citations). Fertilizers and amendments address these issues. They support healthy plant growth globally.
What is the cost of salinity tolerance in crops?
Munns and Gilliham (2015) analyzed yield reductions from soil salinity in "Salinity tolerance of crops – what is the cost?" (1245 citations). Inadequate drainage and global warming exacerbate affected land. Most plant species experience growth inhibition.
