Besides enabling economic activity, the domestication of indigenous species in situ configures a strategy for the conservation of genetic resources in Agroforestry Systems (AFSs), as well as an ecological restoration strategy. Successful productivity and restoration through AFSs require active intervention with agroecological practices, e.g., the use of green manure. We evaluated how planting different green manure species in consortium with Guavira influences its reproductive period, growth, and productivity in different spatial arrangements. Guavira, Campomanesia adamantium, is a shrub that is native to the Brazilian Savannah and has fruticulture potential. To evaluate growth, we measured plant height and canopy cover and to evaluate fruit yield, we monitored reproductive phenology among different treatments. Guavira grows better in less dense areas with Crotalaria breviflora and Cajanus cajan rather than with Canavalia ensiformis. In all inter-row spacing of Guavira and green manure species, the reproductive phases were highly seasonal, with flowering and fruiting lasting for 2 and 4 months, respectively. Guavira plants that grew in consortium with green manure in different inter-row spacing presented different flowering times, but this difference was not reflected in fruit production. Fruiting and growth appear to be affected by inter-row spacing, as well as by the species used in the consortium. Thus, these variables must be considered carefully when implementing an agroforestry system.

Campomanesia adamantium (Cambess) O. Berg 在农林业系统中与绿肥物种间作的生长、开花和结果

除了促进经济活动外,本地物种的原地驯化构成了农林业系统 (AFS) 中遗传资源保护的战略,以及生态恢复战略。通过 AFS 成功实现生产力和恢复需要积极干预农业生态实践,例如使用绿肥。我们评估了与 Guavira 联合种植不同绿肥物种如何影响其在不同空间安排下的繁殖期、生长和生产力。Guavira, Campomanesia adamantium,是一种原产于巴西大草原的灌木,具有果树栽培潜力。为了评估生长,我们测量了植物高度和冠层盖度,并为了评估果实产量,我们监测了不同处理之间的繁殖物候。Guavira 在密度较低的地区与 Crotalaria breviflora 和 Cajanus cajan 相比,在 Canavalia ensiformis 中生长得更好。在瓜维拉和绿肥品种的所有行距中,繁殖期都具有很强的季节性,开花和结果分别持续了 2 个月和 4 个月。不同行距下绿肥联合生长的番石榴植株开花时间不同,但这种差异并未体现在果实产量上。结果和生长似乎受到行间距以及联合体中使用的物种的影响。因此,在实施农林业系统时必须仔细考虑这些变量。繁殖期具有很强的季节性,开花和结果分别持续 2 个月和 4 个月。不同行距下绿肥联合生长的番石榴植株开花时间不同,但这种差异并未体现在果实产量上。结果和生长似乎受到行间距以及联合体中使用的物种的影响。因此,在实施农林业系统时必须仔细考虑这些变量。繁殖期具有很强的季节性,开花和结果分别持续 2 个月和 4 个月。不同行距下绿肥联合生长的番石榴植株开花时间不同,但这种差异并未体现在果实产量上。结果和生长似乎受到行间距以及联合体中使用的物种的影响。因此,在实施农林业系统时必须仔细考虑这些变量。以及联盟中使用的物种。因此,在实施农林业系统时必须仔细考虑这些变量。以及联盟中使用的物种。因此,在实施农林业系统时必须仔细考虑这些变量。
