Grow a tomato inside a square box, and you’ll end up with a square tomato. It’s an experiment that shows clearly how confinement can influence a body’s evolving shape.
Urbanization delays spring plant growth in warm regions（图）
Urbanization delays spring plant growth warm regions
2019/11/22
The first appearance of bright green leaves heralds the start of spring, nudging insects, birds and other animals into a whirlwind of action. But a new NSF-funded study shows that urbanization shifts ...

Shining a Light Plant Growth Development
2017/12/19
Plants don’t have eyes, but they do “see” their surroundings using light.That’s made possible by proteins called photoreceptors that absorb light and convert it into a signal that turns genes on or of...
From Alaska To Amazonia:First Global Maps Of Traits That Drive Vegetation Growth（图）
Alaska Amazonia:First Global Maps Drive Vegetation Growth
2017/12/19
Based on measurements of 45,000 individual plants from 3,680 species, and using high-tech statistical mapping protocols, the team created global maps of plant traits including leaf nitrogen concentrat...
Researchers develop equation that helps to explain plant growth（图）
Researchers equation plant growth
2017/3/30
It is rare in biology that a single trait can answer questions spanning several fields of research. One such trait is plant biology’s “leaf mass per area,” a simple measurement calculated by weighing ...
Gene network controls how many flowers and fruits plants will produce during critical growth window
Gene network controls flowers and fruits plants critical growth window
2016/11/29
There is staggering diversity in the number of flowers produced by each of the 2,800 or so species of plants in the nightshade family, which includes economically important crops such as tomatoes, pep...
Ethylene is involved in nitrate-dependent root growth and branching in Arabidopsis thaliana
Arabidopsis thaliana ethylene production lateral root development nitrate concentration nitrate transporters
2015/2/5
Here, we investigated the role of ethylene in high nitrate-induced change in root development in Arabidopsis thaliana using wild types and mutants defective in ethylene signaling (etr1, ein2) and nitr...
BLOOMINGTON, Ind. -- Research by Indiana University geologists suggests that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater rive...
Shrub growth decreases as winter temperatures fluctuate up
Shrub growth decreases winter temperatures fluctuate up
2014/6/12
Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs because the growing season would be longer. But shrubs achieve less yearly growth when...
Parametric identification of a functional-structural tree growth model and application to beech trees (Fagus sylvatica)
Parametric identification functional-structural tree growth model application to beech trees
2010/11/16
Functional-structural models provide detailed representations of tree growth and their application to forestry seems full of prospects. However, owing to the complexity of tree architecture, parametr...
Modeling the effects of cymene on the distribution of germination and growth of Beauveria bassiana
Modeling effects cymene distribution germination growth Beauveria bassiana
2010/11/15
Essential oils have antifungal and antipathogenic effects and therefore are targets in plant pathology research for their potential uses as natural substitutes for inorganic plant pesticides. Beauveri...
The effects of gibberellic acid and kinetin on overcoming the effects of juglone stress on seed germination and seedling growth
Juglone stress alleviation gibberellic acid kinetin seed germination seedling growth
2010/3/17
Juglone (5-hydroxy-1,4-naphthoquinone) is an allelochemical responsible for walnut allelopathy. The effects of gibberellic acid (GA3) and kinetin (KIN) on overcoming the effects of juglone stress on s...
Callus induction, biomass growth, and plant regeneration in Digitalis lanata Ehrh.: influence of plant growth regulators and carbohydrates
Callus regeneration carbohydrates nitrogen source rooting
2010/3/17
The effect of plant growth regulators (PGRs) and carbohydrate sources on callus induction, callus growth, and plant regeneration in foxglove was examined. Explants were transferred onto MS medium with...
STUDIES ON ECOLOGICAL PREREQUISITES FOR GROWTH OF PINELLIA TERNATA
Rinella ternata ecological Preretwsites temperature soil humidity light intensity
2009/5/31
Results of the Present paper show that the normal growth of Pinellia ternata requires the following three ecological Pre-requisites:warm climate (suitable temperatare is l0 ~ 27℃), higher soil humidit...
ISU researcher identifies genetic pathway responsible for much of plant growth
