“…Fine roots are relevant in seedling quality assessment; they are often linked to success in overcoming transplant stress (Kormanik 1986;Ruelhe & Kormanik 1986;Dey & Parker 1997;Tsakaldimi et al 2009). Fine roots are related to seedling transport functions and water and mineral nutrient uptake (Wilson et al 2007) and also to root growth potential both in conifers and hardwoods (Burdett 1979;Deans et al 1990;Gazal et al 2004). In oak, the FOLR fraction recorded in Air-pots was similar to the other pots, contrasting with the specific structure of this pot, which is designed to promote root fiborsity (Privett & Hummel 1992;Marler & Willis 1996;Amoroso et al 2010).…”

Container size and shape impacts biomass allocation of nursery seedlings. Effects of different pot types on shoot and root growth and biomass allocation were evaluated in nursery cultivation of Quercus robur L. and Juglans regia L. We compared two containers currently used in Italian forest nurseries (ISSA-pot®; Plastecnic®) and two alternative types (Superoots Air-pot®; Tubex®); different pot sizes were also included: two for ISSA-pot and Plastecnic; four for Air-pot. Seedlings were evaluated during 1-year nursery growth and biomass allocation was determined on a sub-sample at the end of the growing season. For both species, seedlings grown in larger containers generally grew more and containers >4.5 l produced the largest seedlings. Root biomass was >50% of total biomass in all containers with the tap-root comprising the major root system component. Air pruning in the Air-pots inhibited seedling growth of both species in narrow deep pots, while in bigger sizes (wide and deep) it produced positive responses, especially for walnut. Container configuration differentially affected the studied species: shoot and root system development of walnut seedlings was more limited by pot diameter than depth. Q. robur had improved shoot and root system development when grown in Tubex.

Aquilaria crassna, an exsotic plant species in Indonesia is naturally distributed in Cambodia, Laos, Thailand and Vietnam. The aim of this research was to determine the effectiv eness of arbuscular mycorrhizal fungi namely Glomus sp. 1, Glomus sp. 2 on height and diameter growth in both nursery and field. Experiment in the nursery was designed using completely randomized design while in the field using completely randomized block design with three treatments of control, Glomus sp. 1, and Glomus sp. 2. Results indicated that Glomus sp. 1 and Glomus sp. 2 were able to increase height and diameter plant growth of eight-month-old A. crasna seedlings as much as 123%, 122% and 42%, 47%, respectively, compared to control, and increasedroot dry weight, shoot dry weight, and total dry weight significantly as much as 133%, 143%, 193%, 174% and 173%, 164%, respectively, compared to control. Height and diameter growth of six-month-old A. crassna in the field, where seedlings were inoculated by Glomus sp.

Abstract. Manipol MM, Tinio CE, Maldia LSJ, Combalicer MS. 2020. Salinity-induced changes in the morphology, physiology, and anatomy of seeds and seedlings of smooth narra (Pterocarpus indicus Willd. f. indicus). Biodiversitas 21: 5146-5154. Pterocarpus indicus Willd. forma indicus is a commonly planted species for reforestation in the Philippines regardless of the area’s condition. Since the species could survive in areas even with harsh conditions, it was hypothesized that the species may also thrive in areas having substantial amount of salt, especially during its early growth. This study assessed the morphological, physiological, and anatomical responses of seeds and seedlings of P. indicus Willd. f. indicus (Fabaceae), a native species in the Philippines to varying salt (NaCl) concentrations (0-300 mM). Based on the results, P. indicus f. indicus grew significantly in terms of height, number of leaves, leaf area, root collar diameter (RCD), root nodules, and root-shoot ratio in the control and at 100 mM NaCl. On the other hand, the growth of the species was suppressed at 300 mM NaCl. The physiological characteristics (germination, survival, and photosynthetic rates) were also high in the control compared to the NaCl treatments. As for the seed anatomical characteristics, the radicle cells remained undamaged, with high cell number and longer cells in the control, but showed damaged and reduced cell number and length at 300 mM NaCl. This indicates that P. indicus f. indicus can only tolerate moderate saline soil conditions. Hence, this result needs to be considered in reforestation efforts of the country using this species.
