ABSTRACT:
Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely the extraction method and measurements with a portable chlorophyll meter, and determined whether the results of these two methods showed a significant correlation. Photosynthetic pigments were measured, using
both methods, in a greenhouse and laboratory, at four developmental stages: the vegetative stages I (30 days after sowing [DAS]), II (60DAS), and III (90DAS), and the reproductive stage (150DAS). The determination of the photosynthetic pigment content in R. sativus and V. sativa, obtained from the extraction method and chlorophyll index,revealed significant differences depending on the developmental stage in both species. Furthermore, the contents of chlorophyll a, chlorophyll b, and carotenoids determined using the extraction method showed high coefficients of
correlation with the total chlorophyll index determined using the portable chlorophyll meter. Therefore, the portable chlorophyll meter can be used for the accurate evaluation of the photosynthetic potential of Raphanus sativus and Vicia sativa, which also saves time and reagents. |

Wheat stem rust, a devastating disease of wheat and barley caused by the fungal pathogen
Puccinia graminis f. sp. tritici, was largely eradicated in Western Europe during the mid-to-late
twentieth century. However, isolated outbreaks have occurred in recent years. Here we
investigate whether a lack of resistance in modern European varieties, increased presence of its
alternate host barberry and changes in climatic conditions could be facilitating its resurgence.
We report the first wheat stem rust occurrence in the United Kingdom in nearly 60 years,
with only 20% of UK wheat varieties resistant to this strain. Climate changes over the past 25
years also suggest increasingly conducive conditions for infection. Furthermore, we document
the first occurrence in decades of P. graminis on barberry in the UK . Our data illustrate that
wheat stem rust does occur in the UK and, when climatic conditions are conducive, could
severely harm wheat and barley production. |
