摘要

非洲茄子(Solanum aethiopicum L.,Gilo 组)是坦桑尼亚最常见的传统蔬菜之一。坦桑尼亚的非洲茄子产量远远低于预期的潜在产量,这主要是由于生物和非生物胁迫造成的。我们在坦桑尼亚的两个地方进行了实验,研究是否可以通过移栽并在播种时接种丛枝菌根真菌(AMF)来显著改善非洲茄子吉洛组的植株生长和果实产量。许多植株,尤其是直接播种的植株,在收获前就已经死亡,此外,许多存活的植株还出现了枯萎症状。托盘育苗移植和播种时使用 AMF 接种菌,使果实产量分别总体显著增加了 30%-40% 和 20%-25%。每个试验小区果实产量的增加主要是由于存活并达到采收期的植株数量增加。然而,种植方法(即移栽或直接播种)和 AMF 接种的确切效果因植物品种的不同而有很大差异。需要进一步研究了解植物死亡的原因,以便制定适当的植物管理方法。

Effects of transplanting and AMF inoculation on the fruit yield of African eggplants (Solanum aethiopicum and Solanum anguivi) in Tanzania
The African eggplant (Solanum aethiopicum L., Gilo group) is one of the most common traditional vegetables in Tanzania. The yield of the African eggplant in Tanzania is far lower than the potential yield expected, which is due primarily to biotic and abiotic stresses. We conducted experiments at two locations in Tanzania to study whether or not plant growth and the fruit yield of the Gilo group of African eggplant can be significantly improved through transplanting coupled with the inoculation of arbuscular mycorrhizal fungi (AMF) at sowing. Many plants, particularly for the directly sown treatment, died well before harvesting, and, in addition, many surviving plants showed symptoms of wilting. The transplanting of tray seedlings and using AMF inocula at sowing led to an overall significant increase in fruit yield by 30%–40% and 20%–25%, respectively. Increased fruit yield per experimental plot resulted primarily from a greater number of plants that survived and reached the harvesting stage. The exact effect of planting method (i.e., transplanting or direct sowing) and AMF inoculation, however, varied greatly with plant accessions. Further research is needed to understand the cause(s) for plant mortality in order to develop appropriate plant management practices.
