Abstract
The genus Khaya holds significant value in the national and international forest market due to its noble wood. However, the limited understanding of species-climate interactions hinders its expansion in Brazil. To address this, we investigated the effects of different microclimates on the growth of Khaya ivorensis , Khaya senegalensis , and Khaya anthotheca seedlings, considering variations in mean air temperature (T), vapor pressure deficit (VPD), and water availability. Seedlings were cultivated in controlled environments representing three microclimates (I: 24.7 °C, 0.30 kPa VPD; II: 28.6 °C, 0.95 kPa VPD; III: 29.8 °C, 1.80 kPa VPD) with varying water availability levels (20%, 40%, 60%, and 90% of maximum water holding capacity). Growth variables were assessed. Our findings indicate that water restriction reduced seedling growth across all microclimates, leading to lower total dry mass production. Specifically, K. ivorensis exhibited robust growth under microclimates with higher water availability. K. senegalensis displayed optimal initial growth in microclimate III (29.8 °C, 1.80 KPa), particularly when subjected to higher water availability levels in the substrate.
期刊介绍:
Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences.
The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
