摘要

摘要本研究旨在评价14个尿毒草品种对baldanorum Azospirillum Sp245的接种反应。评价品种为:Marandú、xara、Paiaguás、Piatã、Basilisk、B140、Comum、Tupi、H47、Llanero、Ruziziensis、Ipyporã、Mulato和Convert HD364。进行了三个试验来测量根系性状:两个用土壤，一个用无菌基质。与对照相比，单次施用baldanorum Sp245增加了Marandú、Llanero、Ruziziensis和Convert HD364的干物质积累和根系数量。但接种后，xarasamass和Ipyporã品种的一些根系性状值较低。

Growth promotion in different Urochloa species inoculated with Azospirillum baldaniorum

Abstract The objective of this work was to evaluate inoculation response to Azospirillum baldaniorum strain Sp245 in 14 Urochloa cultivars. The evaluated cultivars were: Marandú, Xaraés, Paiaguás, Piatã, Basilisk, B140, Comum, Tupi, H47, Llanero, Ruziziensis, Ipyporã, Mulato, and Convert HD364. Three experiments were conducted to measure root traits: two using soil and one a sterile substrate. Compared with the control, a single application of A. baldaniorum Sp245 increases dry matter accumulation and number of roots in cultivars Marandú, Llanero, Ruziziensis, and Convert HD364. However, after inoculation, cultivars Xaraés and Ipyporã show some root traits with lower values.
