    en.wikipedia.org/wiki/Erythroxylum_novogranatense

    In controlled environment studies, the optimum average daily temperature for leaf growth for E. novogranatense var. novogranatense was found to be around 27 °C (81 °F), whereas leaf growth was generally higher at photosynthetic photon flux densities (PPFD) of 250 or 400 micromol per meter square per second than at 155 micromol per meter ...

    The plants thrive best in hot, damp and humid locations, such as the clearings of forests; but the leaves most preferred are obtained in drier areas, on the hillsides. The leaves are gathered from plants varying in age from one and a half to upwards of forty years, but only the new fresh growth is harvested.

    An alternative method of growth curve analysis is latent growth curve modeling using structural equation modeling (SEM). This approach will provide the same estimates as the multilevel modeling approach, provided that the model is specified identically in SEM. However, there are circumstances in which either MLM or SEM are preferable: [4] [6]

  5. Plant growth analysis - Wikipedia

    en.wikipedia.org/wiki/Plant_growth_analysis

    Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .

    Figure 1: A bi-phasic bacterial growth curve.. A growth curve is an empirical model of the evolution of a quantity over time. Growth curves are widely used in biology for quantities such as population size or biomass (in population ecology and demography, for population growth analysis), individual body height or biomass (in physiology, for growth analysis of individuals).
