“…We found low rates of seedling survival, consistent with previous studies on Quercus establishment in Mediterranean environments (Rey Benayas et al 2005;Castro et al 2006;Valdecantos et al 2006;Del Campo et al 2010, Cuesta et al 2010a. As we anticipated (H3), most of this mortality was a consequence of seedling predation; all of unprotected seedlings in the seeding experiment and at least 50 % of the naturally established seedlings (which were not protected) were predated by the end of the first growing season.…”

Predation and aridity slow down the spread of 21-year-old planted woodland islets in restored Mediterranean farmland

et al. 2015

Planted woodland islets act as sources of seed that may accelerate woodland development in extensive agricultural landscapes. We assessed a 1-ha plot that was planted with 16 100-m 2 islets of holm oak Quercus ilex subsp. ballota seedlings near Toledo (Spain) in 1993. In spring 2014 we measured (1) acorn predation and (2) seedling emergence from seeded acorns at different distances from and orientations around the islets with half of the acorns protected to prevent predation, (3) survival of emerged seedlings, and (4) natural tree establishment outside of the planted islets. Most (96.9 %) unprotected acorns were removed or predated. Seedling emergence from protected acorns ranged from 42.9 % on the northern side of the islets to 13.2 % on the southern side, suggesting a less stressful microclimate on the northern side. Survival of naturally established seedlings was 28.6 % by the end of first summer; seedling mortality was chiefly due to drought (45.0 %) and herbivory (35.0 %). Density of emerged seedlings, surviving seedlings after first dry season, and established oaks [1-year old was similar at different distances from the islets. Over the 21 year time period, 58 new oak individuals [1-year old have established (an average of 3.3 established individuals per ha per year) at an average distance of 6.3 ± 5.4 m away from the closest islet. We conclude that initial oak regeneration triggered by small planted islets in Mediterranean abandoned farmland is slowed down by high acorn predation, seedling herbivory, and stressful microclimatic conditions. Regardless, these islets are a viable tool for regeneration of Mediterranean oak woodland.

“…The influence of such quality has been studied considering the performance of such seedlings in the field and is a consequence of the time the seedlings have lived from nursery until planting (Del Campo;Navarro;Ceacero, 2010). In this context, the concept of 'target seedlings', which present a minimum standard of quality in order to be planted in the field, has been discussed and applied to the eucalyptus culture (Close, 2012).…”

The introduction of organic production in coffee growing has demanded an increase for information on seedling production with standard of quality. Hence, the purpose of the present work was to evaluate how the amount of organic substrate in black and white nonwoven fabric (NWF) bags in four different sizes influences the quality index of Coffea arabica L. seedling produced in an organic system. The quality parameters evaluated were leaf area; number of leaves; plant height; collar diameter; dry matter of leaves, stalk, root and total. Whereas the parameters of quantity were the relation between shoot dry matter and root dry matter (RSR); the relation between shoot height and stem diameter (RHD) and the Dickson Quality Index (DQI). Seedlings produced in 1200 mL black containers presented the best results in most of the evaluated parameters. Seedlings produced in 410 mL containers presented Dickson Quality Index of 0.2, which is the index described by other authors as the adequate standard of quality for seedlings.

“…Choosing an inappropriate acorn provenance and the use of species not adapted to the plantation area are causing in some cases the plant inadequacy, which leads to poor growth and, in extreme cases, tree death (Andivia et al, 2012;Del Campo et al, 2010).…”

Phytosanitary problems detected in black truffle cultivation. A review

et al. 2014

View full text Add to dashboard Cite

Aim of study: In black truffle plantations, many factors are driving the emergence of new pests and diseases which in forestry areas go unnoticed. Usually, the incidence of most of them is low. Nevertheless, in specific cases, some of them are capable of causing irreversible damage that could endanger the harvest or even tree survival.Area of study: This paper presents an in-depth study of the pests and diseases more frequently associated with truffle plantations in the region of Aragón (Spain). Damages have been arranged into the main production stages: nursery, plantations and fruiting bodies.Material and methods: The data used in this work come from the technical enquiries from truffle growers to researchers and technical staff, as well as from field visits undertaken by those work teams.Sampling methodology has been carried out following standard procedures. Insects were collected with the traps commonly used in entomology works.Main result: More than 50 damages have been described in this paper. Some of them are capable of weakening the plants and other can even kill them. Mycorrhizal competitor fungi have also been considered in this paper. These organisms do not cause real phytosanitary problems, but they can lead to important economic losses.Research highlights: Researches, truffle hunters and managers must be alert in the face of the possible occurrence of potentially dangerous organisms. The final aim: being able to take action in an efficient way in the case of a pest outbreak.Keywords: Tuber melanosporum; Quercus; parasites; pests; diseases.
