Morphological and Phenological Responses of Eragrostis plana Nees and Eragrostis pilosa (L.) P. Beauv. Plants Subjected to Different Soil Moisture Conditions
ABSTRACT: Experiments were run in a greenhouse where samples of Eragrostis pilosa and Eragrostis plana, species that infest rice crops, were subjected to three soil moisture conditions (50% of soil water retention capacity (WRC), 100% of WRC, 10 cm water depth), simulating three different environments (upland, lowland and irrigated rice farm, respectively), with the aim of studying how these conditions affect the morphology and vegetative cycle of these plants, by means of development and growth assessments. Results show that each species responds differently when subjected to varying amounts of water in the soil. Soaking the soil with 10 cm of water was the treatment that most negatively influenced the development of E. plana plants, reducing the formation of panicles per plant, as well as the aerial part dry mass. The responses of E. pilosa plants to the waterlogged environment manifested as reductions in tillering parameters, number of panicles per plant, root and aerial part dry mass, changes in flag leaf formation, and vegetative cycle increases, which allows inferring that these plants are more sensitive to hypotoxic environments. Thus, the water depth treatment is possibly what caused negative effects on the development of the study plants, which indicates that water management in irrigated rice farming is of uttermost importance for management of invasive plants.

期刊介绍:
Planta Daninha is a scientific journal published by the Brazilian Society of Weed Science (SBCPD - Sociedade Brasileira da Ciência das Plantas Daninhas). Papers submitted for publication must be sent through an electronic system, on http://www.scielo.br/pd. Works may be written in Portuguese, English, or Spanish, and will be accepted after being reviewed and approved by the Editorial Board. Only papers that have not been published or submitted for publication in other media will be accepted. Articles in Portuguese will be translated to English after being properly corrected and authorized by the authors. Planta Daninha has with goal to publish genuine technical-scientific papers and literature reviews from a critical perspective on Biology, weed management, and related topics.
