Leaf area ratio and net assimilation rate of 24 wild species differing in relative growth rate
Oecologia, 1990Which factors cause fast-growing plant species to achieve a higher relative growth rate than slow-growing ones? To answer this question 24 wild species were grown from seed in a growth chamber under conditions of optimal nutrient supply and a growth analysis was carried out.

Remote sensing observations of vegetation derived from satellite retrievals provide spatially comprehensive measurements that are well-suited for data assimilation in land surface modeling over large areas. However, the temporal intervals of such satellite-based observations are usually multi-daily or monthly, which may not be frequent enough to ...

A Multiscale Assimilation Approach to Improve Fine-Resolution Leaf Area Index Dynamics
IEEE Transactions on Geoscience and Remote Sensing, 2019Fine spatial details of vegetation growth are usually lost in leaf area index (LAI) products obtained from coarse spatial resolution satellite sensors. This may bring uncertainties in ecosystem process models, which usually require LAI products with fine spatiotemporal resolutions.

Our limited ability to accurately simulate leaf phenology is a leading source of uncertainty in models of ecosystem carbon cycling. We evaluate if continuously updating canopy state variables with observations is beneficial for predicting phenological events. We employed ensemble adjustment Kalman filter (EAKF) to update predictions of leaf area index (

Predicting plant leaf area production: shoot assimilate accumulation and partitioning, and leaf area ratio, are stable for a wide range of sorghum population densities [PDF]
, 2002 Predicting plant leaf area production is required for modelling carbon balance and tiller dynamics in plant canopies. Plant leaf area production can be studied using a framework based on radiation intercepted, radiation use efficiency (RUE) and leaf area ratio (LAR) (ratio of leaf area to net above-ground biomass).

LEAF AREA AND NET ASSIMILATION RATE AS DETERMINANTS OF CROP YIELD
1966The relation of agronomic practice to crop yield is discussed in terms of photosynthetic efficiency of the crops (as measured by Leaf Area and Net Assimilation rates). The importance of a study of these factors in certain tropical crops is indicated.

AbstractThe low returns from nitrogen fertilization in central and eastern Sudan stimulated an investigation into the response of grain yields of irrigated wheat (Triticum aestivum L. em. Thell.) to two sources of nitrogen (ammonium sulfate and urea), two methods (broadcasting and sidedressing), and several times of application.
