Postharvest senescence of fresh lotus pods and seeds is delayed by treatment with 1 ‐methylcyclopropene
Absract
Fresh lotus pods were treated with 1‐methylcyclopropene (1‐MCP) at a concentration of 0.5 μL L−1 for 24 h at 25°C and then stored at 25°C for 8 days. First, their quality and physiological changes during storage were measured in terms of visual appearance, respiration rate, firmness, and the contents of sugars, protein, total phenolics and malondialdehyde (MDA). The results showed that the 1‐MCP treatment reduced the browning of fresh lotus pods, and inhibited the respiration rate during storage. In addition, the 1‐MCP treatment alleviated changes in firmness, delayed starch and protein degrada...

Seed treatment with salicylic acid invokes defence mechanism of Helianthus annuus against Orobanche cumana
Abstract
The root holoparasitic angiosperm sunflower broomrape (Orobanche cumana) specifically affects sunflower (Helianthus annuus) growth and causes severe damage all over the world. This investigation was designed to examine the protective effects of salicylic acid (SA) treatment to the seeds of an O. cumana‐susceptible cultivar of sunflower (TK0409). Sunflower seeds were pretreated with different concentrations (0, 0.5 and 1 mM) of SA and inoculated with O. cumana for 4 weeks. O. cumana infection resulted in reduction in plant biomass, endogenous SA level, and the expression of SA‐related genes including pal, c...

New phenological growth stages of garlic (Allium sativum)
Abstract
The advantages of using Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie (BBCH) phenological scales are well‐known in the field of agronomy. Currently, specific scales exist for the majority of crops. Although garlic has international importance due to its worldwide cultivation, a specific phenological scale has not been developed; in general, garlic is integrated into the BBCH description for onion. While garlic and onion belong to the same genus, this generalisation should be avoided due to their many differences. The means of propagation of garlic is vegetative, from cloves of the previous c...

Sporisorium scitamineum colonisation of sugarcane genotypes susceptible and resistant to smut revealed by GFP ‐tagged strains
We examined (GFP)‐tagged S. scitamineum infecting tissues of three sugarcane genotypes with distinct responses to smut (susceptible, intermediate resistant and resistant). Mating compatible haploid cells gfp‐expressing were obtained by Agrobacterium tumefaciens‐mediated transformation (ATMT) using the integrative vector pFAT‐gfp. Regardless of the inoculation method (drop inoculation and hypodermal syringe inoculation), all genotypes were colonised by the fungus. GFP‐tagged strains of opposite mating reaction were able to: (a) grow in vitro as fluorescent yeast‐like cells; (b) generate infectious dikaryon; (...

Genetic diversity and population structure of Sorghum mosaic virus infecting Saccharum spp. hybrids
Abstract
Sugarcane mosaic disease is widespread in many countries and has been identified to be caused by Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV) and Sugarcane streak mosaic virus (SCSMV). Viral surveys of SCMV, SrMV and SCSMV were performed from 104 leaf samples of Saccharum spp. hybrid growing in China and two leaf samples in Myanmar. Sorghum mosaic virus was a major causal agent for sugarcane mosaic disease in China whereby 72.1% (75/104) of samples had SrMV infection alone, 6.7% (7/104) were mixed with SCMV and 17.3% (18/104) were mixed with SCSMV. Sugarcane streak mosaic virus infection alone occurr...

Arbuscular mycorrhizal fungi induced changes in rhizosphere, essential oil and mineral nutrients uptake in dill/common bean intercropping system
Abstract
The fundamental aim of this research was to evaluate the effects of Funneliformis mosseae on nutrient uptake and distribution in solo cropping and intercropping of common bean Phaseolus vulgaris and dill Anethum graveolens in the field, using a factorial arrangement of treatments. The factors were seven cropping systems including (a) common bean sole cropping (40 plants m−2), (b) dill sole cropping at different densities (25, 50 and 75 plants m−2) and (c) the additive intercropping of dill/common bean (25/40, 50/40 and 75/40 plants m−2), with (+AM) or without (−AM) arbuscular mycorrhiza coloni...

Fruiting pattern in longan, Dimocarpus longan: from pollination to aril development
Abstract
In most fleshy fruits, the edible part of the fruit is formed either by the pericarp derived from the ovary wall or by an engrossed receptacle. However, in a number of fruit tree species the edible part is the aril, an outgrowth of the ovule that envelops the seed, and there is a paucity of information on fruit development and fruiting pattern in these crops. To fill this gap, in this work, we have characterised the progamic phase, fruit development and fruit/fruitlet drop in longan, Dimocarpus longan. The progamic phase from pollination to fertilisation took just 3 days; the pollen tubes arrived to the base of ...

Mycorrhizal associations and soil properties of native Allanblackia stuhlmannii stands in the Eastern Usambara Mountains, Tanzania
Abstract
Allanblackia stuhlmannii is a tree species currently under domestication. Potential mycorrhizal relationships of A. stuhlmannii and soil properties of native stands were investigated to determine the soil–environmental requirements of the species. Roots and soil samples were collected from five sites with A. stuhlmannii stands along an altitudinal transect in Amani Nature Reserve, Tanzania. Mycorrhizal status was investigated by combining microscopy with molecular analysis of the fungal communities. Soil adjacent to the A. stuhlmannii seedlings was analysed for physical and chemical properties and the sites were...

The red imported fire ant, Solenopsis invicta, modifies predation at the soil surface and in cotton foliage
We examined the contribution of fire ants to predation at the soil surface and in cotton foliage at two sites and over the course of two field seasons in Georgia, using egg masses of the beet armyworm, Spodoptera exigua. To assess interactions between fire ants and other arthropod species, we also measured the densities of edaphic predators and honeydew‐producing hemipterans at both sites. The sites occurred in different growing regions (Piedmont and Coastal Plain), and allowed us to characterize the importance of fire ants as predators under different climatic and soil conditions. Fire ant suppression decreased egg pred...

Leaf traits as indicators of limiting growing conditions for lettuce (Lactuca sativa)
Abstract
Lettuce growth under unstressed conditions was compared to growth under four limiting conditions, i.e. no phosphorus fertilization (0_P), no nitrogen fertilization (0_N), low light (LR) and water stress (WR) over two different growing periods. We investigated the adaptive changes in terms of the morphological and physiological leaf traits, identifying stress‐specific and ‘stable’ indicators suitable for use in breeding programmes. The plants subjected to the WR treatments had lower leaf expansion and specific leaf area (SLA), as well as lower soil–plant analysis development (SPAD) values, stomatal conducta...

Bio‐efficacy of a chitosan based elicitor on Alternaria solani and Xanthomonas vesicatoria infections in tomato under tropical conditions
This study investigated the ability of a commercial chitosan extract (Armour‐Zen®) to reduce disease incidence and induce the production of enzymes and expression of marker genes involved in plant defences for two important tomato pathogens, Alternaria solani and Xanthomonas vesicatoria. Foliar spray applications of the chitosan extract significantly reduced the incidences of both diseases in greenhouse and field grown tomato plants and also displayed a positive effect on growth and yields of tomato fruits. Chitosan‐treated plants recorded elevated levels of defence enzymes and upregulation of the PIN II marker gene f...

The phytoplasma associated with purple woodnettle witches'‐broom disease in Taiwan represents a new subgroup of the aster yellows phytoplasma group
Abstract
In October 2013, a new disease affecting purple woodnettle, Oreocnide pedunculata, plants was found in Miaoli County, Taiwan. Diseased plants exhibited leaf yellowing and witches'‐broom symptoms. Molecular diagnostic tools and electron microscopic cell observation were used to investigate the possible cause of the disease with a specific focus on phytoplasmas. The result of polymerase chain reaction with universal primer pairs indicated that phytoplasmas were strongly associated with the symptomatic purple woodnettles. The virtual restriction fragment length polymorphism (RFLP) patterns and phylogenetic analysis...
