The Influence of Removing Tubers on Dry-matter Production and Net Assimilation Rate of Potato Plants

open access: yesAnnals of Botany, 1965
To study the effect of removing tubers on growth and net assimilation rate ( E ) of potato, plants were grown in pots partly filled with soil with the shoot growing through a polythene cover. Tubers developed in the space between the cover and the soil surface.

The Limitations and Robustness of Data Assimilation in Terrestrial Ecosystem Modelling. [PDF]

open access: yes, 2013
Accurately estimating how much carbon is leaving the atmosphere and being taken up by plants, by processes such as photosynthesis, is critical in order to make accurate climate forecasts. There is a large uncertainty of this atmosphere-plant carbon flux,

PHOTOSYNTHETIC AND RESPIRATORY COMPONENTS OF THE NET ASSIMILATION RATES OF SUGAR BEET AND BARLEY [PDF]

open access: yesNew Phytologist, 1965
SummaryThe net assimilation rate (E) of a plant population (the mean rate of increase in total dry weight per unit leaf area, measured over a period of 1 or 2 weeks), represents the excess of the rate of photosynthesis of the leaves (P) over the rate of respiration of the whole plants (R), both expressed per unit leaf area (E=P—R).

Wplyw stopnia krzewienia się roślin na akumulacje biomasy organicznej u niektórych odmian zwyczajnej pszenicy ozimej [Influence of tillering degree on the accumulation of dry matter of some winter wheat varieties]

open access: yesActa Agrobotanica, 2015

Growth index in massai grass under different levels of nitrogen fertilization

open access: yesRevista Brasileira de Zootecnia, 2011
This study aimed to evaluate the growth index of massai grass during two regrowth cycles in a greenhouse under five levels of nitrogen (0, 150, 300, 450 and 600 mg N/dm³ of soil) and eight growth ages (5, 8, 11, 14, 17, 20, 23 and 26 days) in a split ...

Response of vegetative and morphological characteristics of common mesquite (Prosopis juliflora (Swartz) DC.) seedling, under different humidity and light factors [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2015
Light and moisture are two important environmental factors that influence seedling growth, therefore the choice of appropriate combinations of these factors is important for afforestation projects.
