“…In comparisons of diseased with healthy plants, mass per seed is the principal component determining yield differences (MADEIRA et al 1988), but in healthy plants that principal component is normally pod number (ISHAG 1973, NEWTON andHILL 1987). Thus considerable attention has been paid to factors associated with abscission of young bean pods.…”

Factors affecting the retention of faba bean flowers and their development into pods werde investigated. Racemes were scored for the date of anthesis of the first flower, and at maturity, the number of pods that developed. These data were correlated with meteorological data. The primary determinant of whether a flower would be retained was the weather during the 4 days from anthesis: incident light and rainfall accounted for over 55 % of the variation in the retention of flowers within a genotype. The results help to validate the model that the availability of assimilate at the time of pod setting is critical for the development of adequate yield. In some environments, such as the winter‐rainy Mediterranean climate, available light at flowering may be a major yield‐limiting factor. Zusammenfassung Begrenzende Faktoren für den Ansatz befruchteter Blüten bei Fababohnen (Vicia faba L.) Es wurden Faktoren untersucht, von denen der Ansatz der Fababohnenblüten und ihre Entwicklung in Hülsen abhängig ist. Die Blütenstände wurden hinsichtlich des Termins des Blühbeginns der ersten Blüte, der Reife und der Anzahl der enrwickelten Hülsen bestimmt. Diese Angaben wurden mit meteorologischen Daten korreliert. Die erste Bestimmungsmöglichkeit hinsichtlich des Ansatzes einer Blüte ergab sich aus den Witterungsbedingungen während der ersten vier Tage nach Blühbeginn: Lichteinfall und Niederschlag kontrollierten mit mehr als 55 % die Variation des Ansatzes von Blüten für den jeweiligen Genotyp. Die Ergebnisse bestätigen Modellvorstellungen, daß die Verfügbarkeit von Assimilaten zum Zeitpunkt des Hülsenansatzes für die Entwicklung eines angemessenen Ertrages kritisch ist. In einigen Umwelten, so z. B. der Winterniederschlag mediterranen Klimas, weist auf die Bedeutung des verfügbaren Lichtes während der Blüte als ein Hauptfaktor hin, der hinsichtlich der Ertragsbegrenzung wirksam wird.

“…The reproductive capability of infected plants is often decreased : effects include a decrease in seed production (Paul & Ayres, 1986b, e ;Madeira, Clark & Rossall, 1988;Hasan & Aracil, 1991) and a reduction in germination (Emge, Melching & Kingsolver, 1981 ;Alexander & Burdon, 1984;Madeira et al, 1988;Hasan & Aracil, 1991). Many smut fungi (Hodges, 1971 ;Lee, 1981 ;Jennersten et al, 1983 ;Alexander & Antonovics, 1988;Alexander, 1990;Jennersten & Kwak, 1991 ;Ericson et al, 1993) and some rusts (Roy, I 993) sterilize their hosts, with implications for population maintenance.…”

“…Solar radiation data used to compute photosynthetically active radiation (PAR) were obtained from a nearby weather station. Photosynthetically active radiation was calculated assuming 45% of the total solar radiation as PAR (10) 12). Linear interpolations of LAI were used for days between dates of LAI measurements including emergence date, when LAI and dry biomass were assumed to be zero.…”

Radiation use‐efficiency of field beans as affected by soil phosphorus management

A simple approach to modeling dry matter production is based on the assumption that radiation-use efficiency (RUE), which is the amount of dry weight produced per unit of intercepted photosynthetically active radiation (IPAR), is relatively constant for crops adequately supplied with water and nutrients.Recent evidences, however, indicate that RUE is not constant but is strongly affected by environment. Soil stresses also appear to affect RUE but few responses have been documented. Growth analysis data from a field experiment were used to compute RUE of field beans grown at differential phosphorus (P) regimes. The main objective of this study was to assess the effects of soil P management on RUE. Applied P rates significantly increased RUE with values ranging from 0.86 g M/J at 0 kg P/ha to 1.09 g M/J at 200 kg P/ha. The relationship between total dry matter and cumulative EPAR was linear at low P regimes but resembled a curvilinear relationship at high P regimes. The RUE of beans under high soil P regimes was not constant but decreased over time.
