Growth and Quality of Leucochloron incuriale Seedlings Subjected to Liming and Phosphorus

Abstract

Leucochloron incuriale can be used in projects to restore degraded areas and for logging purpose. Soil has been used in nurseries to produce seedlings; however, most soil types in Brazil have low nutrient availability and high acidity level. The aim of the current study is to assess the effect of liming and phosphate fertilization on the growth and quality of Leucochloron incuriale seedlings. Treatments were arranged in factorial design with five base saturation levels -3.5 (original), 25, 40, 55 and 70% -and six P levels -0, 120, 240, 360, 480 and 600 mg dm -3 -in completely randomized blocks with four repetitions. The morphological features and their relations were assessed 82 days after planting. Phosphorus levels had significant effect on most of the assessed traits. The recommended P dose was 475 mg dm -3 .

MORPHOPHYSIOLOGICAL AND NUTRITIONAL BEHAVIOR OF Hymenaea stigonocarpa Mart. ex Hayne (FABACEAE) SEEDLINGS SUBMITTED TO LIMING

“…This is not uncommon, as several Cerrado species, such as Astronium fraxinifolium Schott, Guazuma ulmifolia Lam, Anadenanthera macrocarpa (Benth.) Brenan, Inga edulis Mart (Silva et al, 2011) and L. incuriale (Santos et al, 2019) have displayed the same behavior in relation to liming.…”

“…However, some studies report no diff erence between pioneer and climax species (Macedo, 2008), and others demonstrate that liming did not promote diff erences even in pioneers, as in the case of Schizolobium parahyba (Vell.) S. F. Blake and Leucochloron incuriale (Vellozo) Barneby and Grimes (Coneglian et al, 2016;Santos et al, 2019). Liming promoted negative responses to seedling growth in Plathymenia foliolosa Benth and Dimorphandra mollis Benth (Freitas et al, 2017b;Cota et al, 2019), while positive response was noted in Dalbergia nigra (Vell.)…”

Physiological and morphological responses of seedlings of Guazuma ulmifolia (Malvaceae) grown under phosphorus levels

“…The results obtained vary as the plants have distinct needs and also variable quality standards. However, in general, P fertilization has promoted positive effects on the early growth of many species (Freitas et al 2017a;Andrade et al 2018;Moreira et al 2018;Santos et al 2019). Although P fertilization benefits are widely publicized, there are still no studies of this nature for some species of food and medicinal importance, such as Guazuma ulmifolia Lam.…”
