“…Finally, the neglected benefits of synzoochory likely are also widespread when considering partially gnawed ripe fruits with hard pericarps. That is likely the case of many tropical species of Bignoniaceae, Capparidaceae, Chrysobalanaceae, and Lecythidaceae families (Kinzey and Norconk 1993, Peres and Baider 1997) as well as temperate species of Betulaceae, Coriariaceae, and Rosaceae families (Kalkman 2004, Kubitzki 2010, Pipinis et al 2018). These benefits could be especially important in plant species producing thick hard fruit pericarps and multi‐seeded fruits such as figs (Bronstein and Hoffmann 1987), citrus species (Peris 2020), some nut‐producing species (Pipinis et al 2018), and palms (Bradford and Smith 1977), as more seeds can potentially escape from predation.…”

For example, Fedriani et al (2012) demonstrated that partial consumption of fully developed ripe fruits by rabbits and small birds increased germination of surviving seeds and, subsequently, seedling emergence and survival in P. bourgaeana (see also Fedriani and Delibes 2013).…”

The overlooked benefits of synzoochory: rodents rescue seeds from aborted fruits

et al. 2020

Large-scale abortion of immature fruits is a pervasive phenomenon across seed plants due to maternal physiological decisions associated with matching resources with fruit crop size. Aborted fruits are usually disqualified from studies of both fruit production and seed dispersal. However, a considerable number of developing seeds occur within immature aborted fruits. We evaluated the untested hypotheses that seeds within aborted fruits are viable and that incomplete predation of seeds within aborted fruits by hoarding rodents provides, in addition to seed movement, increased germination and seedling emergence. To this end, we studied the system composed by the Iberian pear Pyrus bourgaeana and several rodent species in Mediterranean Spain. About a third of aborted fruits found beneath tree canopies (n = 2430) were partially eaten by rodents. Using a seed sowing experiment, we revealed that a considerable fraction of seeds from P. bourgaeana aborted fruits are viable, germinating, and emerging seedlings. Paradoxically, however, these seeds are de facto unviable since they are confined within the extremely hard pericarp of aborted fruits, which prevents any seedling emergence and thus any contribution to tree recruitment. We show that only when rodents partially gnaw the pericarp walls of aborted fruits, seeds that escaped from predation have the prospect of emerging and thus potentially contributing to tree regeneration. Thus, in this and probably in many other similar synzoochore systems, rodents act as rescuers of seeds confined within aborted fruits, conferring the plants a largely overlooked benefit that could shape the reproductive strategy of many plant species.

“…The moisture content is an important factor affecting seed germination via softening of the seed coat and allowing mobility of nutrients (Pipinis et al 2020). According to the physical properties, oil palm trunk plantable bio-pot has a good ability to absorb and retain water, and it clearly performed well in seed germination of bird chili and Thai eggplant seeds, as shown in Fig.…”

The oil palm trunk contains great nutrients for plant growth, and its supporting cells are mostly parallel to the centerline. This study investigated the fabrication of a plantable bio-pot from 5 mm thick sheets of oil palm trunk. The effects of the three zones in the trunk (outer, middle, and inner) and the pressing mold temperature in the range from 160 °C to 200 °C on characteristics of a bio-pot were evaluated. The results demonstrated that the outer zone of an oil palm trunk with 200 °C molding temperature had the highest ultimate compression load, and the pot shape appeared stable after soaking in water for 24 h, showing 105% water absorption. The changes to oil palm trunk chemistry caused by elevated temperature contributed to the mechanical properties and improved durability. The oil palm trunk plantable bio-pots facilitated germination of chili and eggplant seeds. The leaf number, leaf greenness, plant height, and total dry biomass had no significant difference between using the oil palm trunk bio-pot and a plastic pot for a seedling of either of these plants.

“…Therefore, because the thresholds among orthodox, intermediate, and recalcitrant seed behavior are not always well defined, efforts to allocate seeds in a particular category may lead to varied conclusions. For example, in the case of Corylus avellana L., its seeds were already classified as recalcitrant, intermediate and orthodox [ 65 , 66 , 67 ].…”

Seeds are the most commonly used source of storage material to preserve the genetic diversity of plants. However, prior to the deposition of seeds in gene banks, several questions need to be addressed. Here, we illustrate the scheme that can be used to ensure that the most optimal conditions are identified to enable the long-term storage of seeds. The main questions that need to be answered pertain to the production of viable seeds by plants, the availability of proper protocols for dormancy alleviation and germination, seed tolerance to desiccation and cold storage at −20 °C. Finally, it is very important to fully understand the capability or lack thereof for seeds or their explants to tolerate cryogenic conditions. The proper storage regimes for orthodox, intermediate and recalcitrant seeds are discussed.
