Estresse hídrico no metabolismo e crescimento inicial de mudas de Mutambo (<i>Guazuma ulmifolia</i> Lam.)

Ciência Florestal (2011)

Silvana de Paula Quintão Scalon Rosilda Mara Mussury Verusca Luzia de Mello Euzébio Flávia Mitsuko Kodama Camila Kissmann

Este trabalho teve como objetivo avaliar o crescimento inicial das mudas de Guazuma ulmifolia (mutambo) sob diferentes regimes hídricos. As mudas receberam os seguintes tratamentos de água: 100%, 50%, 25% e 12,5% da capacidade de campo e foram avaliadas aos 35 e 83 dias de cultivo nos diferentes tratamentos. A sobrevivência das mudas a 12,5%cc foi menor que nos demais tratamentos, podendo ser avaliadas apenas aos 35 dias. A altura, diâmetro, área foliar, massas seca de parte aérea e raiz foram maiores sob maior disponibilidade de água, entretanto o comprimento médio das raízes não variou entre os tratamentos. A condutância estomática, fotossíntese e transpiração foram menores sob 12,5%cc, porém a eficiência no uso da água não variou entre as diferentes cc. A taxa assimilatória líquida, taxa de crescimento relativo, razão de área foliar e a abertura dos ostíolos diminuíram com as menores cc. Para a produção de mudas de Guzuma ulmifolia o regime hídrico na fase inicial deve ser de 100% da capacidade de campo, porém as mudas crescem satisfatoriamente sob 50%cc. Abaixo de 25%cc as mudas entram em estresse hídrico antes dos 35 dias de cultivo.

Gas Exchange in Caryocar Brasiliense Cambess Seedlings in Water Deficit Conditions

Floresta e Ambiente (2020)

Silvana de Paula Quintão Scalon Flávia Mitsuko Kodama Daiane Mugnol Dresch Zefa Valdivina Pereira Rosilda Mara Mussury

In this study, we assessed the gas exchange in Caryocar brasiliense seedlings in water deficit conditions and their capacity to recover after rehydration. We assessed plant photosynthetic rates, internal carbon concentrations, stomatal conductance, transpiration rates, water-use efficiency, instantaneous carboxylation efficiency, chlorophyll index, and photosystem II quantum efficiency. All gas exchange parameters were reduced after the suspension of irrigation. Seedling photosynthetic rates approached zero after 12 days. The equilibrium was reestablished in all variables 11 days after re-initiating irrigation, with the exception of internal CO2 concentration and stomatal conductance. Exposure of seedlings to water stress resulted in drastically reduced photosynthetic processes. This reduction occurred due to the limitation of stomatal conductance and low rubisco carboxylation efficiency but not to irreversible damage photosystem II. All of these parameters demonstrated recuperation with rehydration, but only the photosynthetic rates reached initial control values.

Initial growth of Campomanesia adamantium (Cambess.) O. Berg. seedlings on substrates with different compositions and water retention capacities

Bioscience Journal (2016)

Daiane Mugnol Dresch Silvana de Paula Quintão Scalon Rosilda Mara Mussury Flávia Mitsuko Kodama

Information on germination, seedling development, and substrates and water requirements of native Savannah species are scarce, for propagation and plantation establishments.Based on this, we evaluated the initial growth of Campomanesia adamantium seedlings sown into tubes containing substrates with different compositions and water retention capacities, including red latosoil; red latosoil and Bioplant ® (1:1); red latosoil, sand, and semidecomposed poultry manure (1:1:0.5);red latosoil and sand (1:1); and red latosoil, sand, and semidecomposed poultry manure (1:2:0.5).The tubes were irrigated three times per week to 25%, 50%, 75%, and 100% of their water retention capacities.The morphological characteristics of the seedlings and their quality indexes were analyzed 52, 83, 114, and 145 days after sowing.We tested all possible combinations of substrates and percentages of water holding capacities, with four replicates (12 tubes).The substrates of red latosoil plus sand and red latosoil plus Bioplant ® were found to be most suitable for the growth and development of C. adamantium seedlings at water retention capacities between 75% and 100%.Growing conditions with water retention capacities of 25% and 50% should not be used to produce seedlings of C. adamantium.
