SHORT COMMUNICATION Germination of kiwifruit, Actinidia chinensis, after passage through Silvereyes, Zosterops lateralis

چکیده
Silvereyes, Zosterops lateralis Latham, commonly feed on kiwifruit rejected for export and either stored in open bins at packhouses or in piles ready to be fed to livestock, and may play a role in the spread of wild kiwifruit in native and exotic forest in the Bay of Plenty, New Zealand. We determined the germination rate and percentage germination of Actinidia chinensis Planch. seed sown (1) after gut passage through silvereyes, (ingested seed), (2) after a standard laboratory fruit pulp removal method (enzyme-extracted seed), (3) as entire fruit and (4) as fruit sections. Ingested and enzyme-extracted seed sown in trays in a glasshouse had nearly identical percentage germination (63.7% and 64.7% respectively) after 71 days. No seed germinated from intact fruit or fruit slices during the experiment. Gut-passage accelerated the germination rate compared with enzyme-extracted seed. This study supports the view that Z. lateralis is involved in dispersing kiwifruit seed into native and exotic forest. ___________________________________________________________________________________________________________________________________

High-density interspecific genetic maps of kiwifruit and the identification of sex-specific markers
Kiwifruit (Actinidia chinensis Planchon) is an important specialty fruit crop that suffers from narrow genetic diversity stemming from recent global commercialization and limited cultivar improvement. Here, we present high-density RAD-seq-based genetic maps using an interspecific F1 cross between Actinidia rufa 'MT570001' and A. chinensis 'Guihai No4'. The A. rufa (maternal) map consists of 2,4...
متن کاملDraft genome of the kiwifruit Actinidia chinensis
The kiwifruit (Actinidia chinensis) is an economically and nutritionally important fruit crop with remarkably high vitamin C content. Here we report the draft genome sequence of a heterozygous kiwifruit, assembled from ~140-fold next-generation sequencing data. The assembled genome has a total length of 616.1 Mb and contains 39,040 genes. Comparative genomic analysis reveals that the kiwifruit ...
متن کاملInvestigation of Antifungal Effect of Actinidia chinensis Extract
Background: Kiwifruit (Actinidia chinensis) belongs to the Actinidiaceae family which is a Chinese endemic plant and is cultivated in New Zealand, USA, Spain, France, Greece, Italy, Japan, Iran and Turkey. Kiwifruit includes different varieties such as Hayward, Bruno, Monty, and Abbott. These varieties are different in taste, odor, shape, and chemical compositions. Some antifungal effect for ...
متن کاملEffect of a magnetic pulse on the orientation of silvereyes, zosterops l. lateralis, during spring migration
The orientation behaviour of Australian silvereyes, Zosterops l. lateralis, was tested during their spring migration, when they head southward to their Tasmanian breeding grounds. With only the local geomagnetic field as a cue, the birds significantly preferred their normal southerly migratory direction. Treatment with a short, strong magnetic pulse designed to alter the magnetization of single...
متن کاملA Randomized Steady-State Bioavailability Study of Synthetic versus Natural (Kiwifruit-Derived) Vitamin C
Whether vitamin C from wholefoods has equivalent bioavailability to a purified supplement remains unclear. We have previously showed that kiwifruit provided significantly higher serum and tissue ascorbate levels than synthetic vitamin C in a genetically vitamin C-deficient mouse model, suggesting a synergistic activity of the whole fruit. To determine if these results are translatable to humans...
