Responses of radish (Raphanus sativus) to drought stress
Abstract
With this study the effects of water deficit on radish growth, dry mass production and partitioning, source–sink relations, physiological responses and accumulation of secondary metabolites in storage roots and leaves have been investigated. Three water stress treatments were applied: (Control) 100% of water holding capacity (WHC), (WS50) 50% of WHC, (WS30) 30% of WHC. Water stress was effectively acquired starting from 287 growing degree days (GDD) as demonstrated by the lower values of relative water content (RWC), higher leaf temperature and NIR‐based water indices values in water stressed conditions. Water...

Seed vigour contributes to yield improvement in dry direct ‐seeded rainfed lowland rice
The objective of this study was to dissect the physio‐morphological characteristics associated with crop establishment and early vigour of DSR under drought and P deficiency conditions in the Philippines. It was found that new drought‐resistant cultivars bred for DSR (Rc348 and Rc192) had faster germination and sprout growth than popular irrigated rice cultivars (Rc222 and Rc10) under soil water deficit due to rapid moisture acquisition by the germinating seeds from drying soils. There was a significant correlation between seed moisture content and the reduction in seed dry weight, and between reduction in seed dry wei...

Gall mite Fragariocoptes setiger (Eriophyoidea) changes leaf developmental program and regulates gene expression in the leaf tissues of Fragaria viridis (Rosaceae)
Abstract
The interaction of plants with certain types of parasites leads to the formation of galls, organised structures that create the habitat of the parasite, caused by an abnormal proliferation of host plant's cells under the influence of growth regulators, secreted by the parasite, or by the plant itself under the influence of the parasite. Arthropods, mites in particular, are the largest group of gall‐inducing phytoparasites, but the mechanisms of their interaction with plants remain virtually unexplored. The interaction of the gall‐inducing eriophyoid mite Fragariocoptes setiger with Fragaria viridis plants was ...

Intercropping hampers the nocturnal biological control of aphids
Abstract
Increasing plant diversity in agroecosystems (i.e. intercropping) has been widely accepted as a means of promoting conservation biological control of mites and insect pests. Nevertheless, the contribution from underlying mechanisms such as the provision of non‐prey alternative food (i.e. pollen and nectar) and shelter have not been properly disentangled; and additionally, it remains unexplored whether the performance of nocturnal and diurnal natural enemies is improved when provided with diverse plant communities. Using open field experiments and a greenhouse microcosm, we investigated whether intercropping coll...

Insecticide resistance and control failure likelihood of the whitefly Bemisia tabaci (MEAM1; B biotype): a Neotropical scenario
Abstract
Insecticide resistance is a standing concern for arthropod pest species, which may result in insecticide control failure. Nonetheless, while insecticide resistance has remained a focus of attention for decades, the incurring risk of insecticide control failure has been neglected. The recognition of both problems is paramount for arthropod pest management and particularly so when invasive species notoriously difficult to control and exhibiting frequent cases of insecticide resistance are considered. Such is the case of the putative whitefly species Middle East‐Asia Minor I (MEAM1) (Bemisia tabaci B‐biotype), fo...

Density ‐independent reproductive success of the hemiparasitic plant Striga hermonthica, despite positive and negative density‐dependent phases
Abstract
The hemiparasite Striga hermonthica is a major constraint to smallholder farmer livelihoods and food security in sub‐Saharan Africa. A better understanding of its life‐cycle can help developing more effective management strategies. Here, we studied density dependence in S. hermonthica on Sorghum bicolor. We exposed two genotypes of S. bicolor that differed in the level of tolerance and resistance to S. hermonthica to a range of seed densities of the parasite. We evaluated multiple host and parasite performance parameters through periodic, destructive harvests and related these to the initial seed density using...

Crop production structure and stability under climate change in South America
We report the results of general patterns in the internal process (biophysical adjustments by rapid negative feedbacks) regulating crop production and analyse how it influences crop persistence and yield ceilings. The structure of a crop yield dynamic system defines its behaviour, but climate variations could displace it from yield equilibrium and affect its stability. Our findings suggest that weather conditions have a stronger impact on yield growth at high rather than at low yield levels (non‐additive impacts). This allows agriculture management to be refined and applied more efficiently, weakening the relationship be...
