Net assimilation rate, specific leaf area and leaf mass ratio: which is most closely correlated with relative growth rate? A meta‐analysis [PDF]

Functional Ecology, 2006
Summary Data were compiled consisting of 1240 observations (614 species) from 83 different experiments published in 37 different studies, in order to quantify the relative importance of net assimilation rate (NAR, g cm−2 day−1), specific leaf area (SLA, cm2 g−1) and leaf mass ratio (LMR, g g−1) in determining relative growth rate (RGR, g g−1 day−1 ...

Estimation of Leaf Area of Taro (Colocasia esculenta)

Jurnal Ilmu Pertanian Indonesia, 2020
Estimation of leaf area by using leaf length and leaf width variables could be done without destruction of the leaves from plants and more practical than using the leaf areameter.

Variability in leaf and crown morphology correlated with light availability in five natural populations of Quercus castaneifolia C.A. Mey

Journal of Forest Science, 2017
In this study, we investigate seedlings of Quercus castaneifolia C.A. Mey, from five different provenances for the research on leaf and crown morphological variations in relation to a light gradient under controlled conditions in a greenhouse.

The effects of different potted mixtures on the growth and development of miniature roses (Rosa ‘Orange Meillandina’) [PDF]

International Journal of Recycling of Organic Waste in Agriculture, 2020
Purpose The miniature rose is one of the most important potted flowers. So far, however, no research has focused on its optimal growing medium. This experiment was performed to evaluate the effects of different media on the growth and development of ...

A Prototype Sensor for Estimating Light Interception by Plants in a Greenhouse [PDF]

, 2008
Light interception is one of the most important factors for plant growth. The intercepted amount depends on the incoming radiation in the greenhouse and the percentage of interception by the crop and is directly related to the leaf area.

Nutrient Solution Concentration Affects Shoot: Root Ratio, Leaf Area Ratio, and Growth of Subirrigated Salvia (Salvia splendens) [PDF]

HortScience, 2004
To evaluate the effects of nutrient concentration and pH of the fertilizer solution on growth and nutrient uptake of salvia (Salvia splendens F. Sellow ex Roem. & Schult. `Scarlet Sage'), we grew plants with five different concentrations of Hoagland nutrient solution [0.125, 0.25, 0.5, 1.0, and 2.0× full strength; electrical conductivity (EC) of 0 ...

Does shade improve light interception efficiency? A comparison among seedlings from shade-tolerant and -intolerant temperate deciduous tree species [PDF]

, 2006
• Here, we tested two hypotheses: shading increases light interception efficiency (LIE) of broadleaved tree seedlings, and shade-tolerant species exhibit larger LIEs than do shade-intolerant ones.
