Phenological growth stages of Montpelier Rock ‐Rose Mediterranean shrub (Cistus monspeliensis): codification and description according to the BBCH scale
Abstract
Shrubland species are important vegetation component resulting from the degradation of Mediterranean forests due to anthropic activities, and constitute the first step of soil covering process subsequent to disturbances such as fire, grazing and deforestation. They represent interesting case studies for their adaptability to challenging climate and soil conditions, and for their potential use in the protection and enhancement of biodiversity. Montpelier Rock‐Rose (Cistus monspeliensis) is a shrubland species growing widespread around the Mediterranean Basin. It is a drought semi‐deciduous species well adapted ...

Intraguild interactions between two biological control agents in citrus fruit: implications for biological control of medfly
Abstract
The parasitoid wasp Spalangia cameroni and the predatory beetle Pseudoophonus rufipes have long been studied for use as biological control agents against the Mediterranean fruit fly Ceratitis capitata, particularly in citrus fruit orchards. Nevertheless, these two species of natural enemies, when competing for a common resource, may experience intraguild predation (IGP) interactions. These possible interactions, affecting parasitism and predation, have been evaluated in the present work, under laboratory conditions, through potential changes in functional response. Regarding host/prey density, both natural enemies...

A nodule endophytic Bacillus megaterium strain isolated from Medicago polymorpha enhances growth, promotes nodulation by Ensifer medicae and alleviates salt stress in alfalfa plants
Abstract
A Gram‐positive, fast‐growing, endophytic bacterium was isolated from root nodules of Medicago polymorpha and identified as Bacillus megaterium. The isolate, named NMp082, co‐inhabited nodules with the symbiotic rhizobium Ensifer medicae. B. megaterium NMp082 contained nifH and nodD genes that were 100% identical to those of Ensifer meliloti, an unusual event that suggested previous lateral gene transfer from a different rhizobial species. Despite the presence of nodulation and nitrogen fixation genes, the endophyte was not able to form effective nodules; however, it induced nodule‐like unorganised structu...

Identification and characterisation of antixenosis and antibiosis to pea aphid (Acyrthosiphon pisum) in Pisum spp. germplasm
In this study, we screened a germplasm collection of Pisum spp. under field conditions over two seasons yielding the identification of a number of accessions with intermediate levels of resistance. Selected accessions were further studied under semi‐controlled and controlled conditions in no choice and choice assays to validate the responses, and to further characterise the mechanisms of resistance operative. Results elucidated the valuable resistance of accession P40 (Pisum sativum ssp. sativum) and P665 (P. sativum ssp. syriacum), with the combination of both antixenosis, by reducing aphid preference, and antibiosis, b...

Growth promotion and root colonisation in pepper plants by phosphate ‐solubilising Chryseobacterium sp. strain ISE14 that suppresses Phytophthora blight
This study was conducted to identify strain ISE14 by 16S rRNA gene sequence analysis and to characterise biocontrol and plant growth promotion activities of the strain in pepper plants. Strain ISE14, identified as Chryseobacterium sp., significantly reduced disease severity in plants inoculated with Ph. capsici and promoted plant growth (lengths and dry weights of shoots and roots) compared with those in plants treated with Escherichia coli DH5α (negative control) or MgSO4 solution (untreated control). This strain effectively colonised pepper plant roots as assessed by bacterial population analysis and confocal laser scan...

Grafting influence on the weight and quality of tomato fruit under salt stress
Abstract
Two commercial tomato cultivars were used to determine whether grafting could prevent decrease of fruit weight and quality under salt stress conditions. The cultivars Buran F1 and Berberana F1 were grafted onto rootstock ‘Maxifort’ and grown under three levels of elevated soil salinity (EC 3.80 dS m−1, 6.95 dS m−1 and 9.12 dS m−1). Fruit weight reduction of grafted plants was lower (about 20–30%) in comparison with non‐grafted ones. Salt stress at the second salinity level (EC 6.95 dS m−1) induced the highest alteration of examined growth and quality parameters. The total increase of phenols, flavo...

Pecan phenology in Southeastern China
Abstract
Pecan (Carya illinoensis) is heterodicogamous, which often leads to unstable yield of its nut crops. Relating pecan orchard management to the phenological stage of the trees is the key to increasing yields; however, describing morphology alone does not lead to an orchard management system that is simple and practical. In this work, we extend the BBCH (Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie) coding method to describe the morphology of the protogynous Mahan pecan cultivar over two consecutive years in southern China. Eight main growth stages, from vegetative bud dormancy to fruit harvest,...

Roles of bacteria in the bark beetle holobiont – how do they shape this forest pest?
Abstract
Bark beetles are well‐known forest pests, some species inducing massive attacks on trees, resulting in the devastation of entire woodlands. Bark beetles are associated with microorganisms, forming an entity known as ‘holobiont’. Beetles and fungi are the best‐studied members of this multipartite symbiosis. However, recent studies have shown that bacteria may play important roles in the bark beetle holobiont, such as providing certain nutrients, promoting the growth of beneficial fungi, detoxifying the environment by lowering the levels of phenolic compounds synthesised by the host tree or by inhibiting the...
