Response of an endangered tree species from Caatinga to mycorrhization and phosphorus fertilization Acta Botanica
Oliveira,João Ricardo Gonçalves de; Silva,Eliene Matos e; Teixeira-Rios,Thaís; Melo,Natoniel Franklin de; Yano-Melo,Adriana Mayumi.
Schinopsis brasiliensis is an endangered tree species found in the Caatinga biome. It presents a characteristic slow development and difficult propagation, although it has been traditionally exploited in the region. Application of arbuscular mycorrhizal fungi (AMF) and phosphorus (P) fertilization may be beneficial to S. brasiliensis development at the seedling stage, which at the same time may help species conservation and the recovery of degraded areas in the Caatinga biome. We assessed the response of S. brasiliensis to AMF inoculation (Claroideoglomus etunicatum and Acaulospora longula) and P fertilization (0, 12, 24, and 48 mg dm−3 addition of P2O5). S. brasiliensis responded positively to both AMF inoculation and P fertilization. At low P...

Growth and physiology of jelly palm (Butia capitata) grown under colored shade nets Agronomy
Costa, Irton de Jesus Silva; Costa, Bárbara Nogueira Souza; Assis, Franscinely Aparecida de; Martins, Adalvan Daniel; Pio, Leila Aparecida Salles; Pasqual, Moacir.
 Butia capitata (Mart.) Becc., commonly known as jelly palm, is a palm tree native to the Cerrado biome. It is considered an endangered species owing to intensive extractive exploitation of its fruits, with slow and uneven seminiferous propagation as an aggravating factor. Thereby, there are some bottlenecks related to jelly palm seedling production that needs to be optimized. Light quality and intensity is very important to seedling production, as it controls the metabolism of plants and consequently their growth and development. Thus, the aim of this work is to evaluate the effect of shade nets on the growth and physiological aspects of jelly palm seedlings. The experimental design was completely randomized, with five treatments, ten replicates and eight...

Different photoprotective responses under drought conditions of two predominant Chilean swamp forest species Gayana Botánica
Bascuñán-Godoy,Luisa; Alcaíno,Claudia; Carvajal,Danny Eduardo; Sanhueza,Carolina; Montecinos,Sonia; Maldonado,Antonio.
Myrceugenia exsucca (DC.) O.Berg (Myrtaceae) and Luma chequen (Molina) A. Gray (Myrtaceae) are two predominants species from swamp forests of Chile. These species present differential microhabitat distribution across soil moisture and north-south precipitation gradients, with only L. chequen being commonly found in lower moisture sites. It is hypothesized that L. chequen has greater plasticity than M. exsucca in the attributes involved in photoprotection under drought conditions. To test this hypothesis: both species were exposed to short term drought treatment. A group of individuals was maintained irrigated (with <img border=0 width=41 height=36 id="_x0000_i1084" src="http://fbpe/img/gbot/v70n2/art08-for1.jpg"...

Avaliação de espécies do Cerrado quanto à tolerância ao alumínio. Infoteca-e
OLIVEIRA, A. P. de; DUSI, D. M. de A.; WALTER, B. M. T.; GOMES, A. C. M. M.; NORONHA, S. E. de; BRAGA, M. B.; COELHO, C. M.; BARROS, L. M. G..
Nos solos ácidos o alumínio (Al) encontra-se na forma de cátions, que são tóxicos para a grande maioria dos vegetais. O Al prejudica o desenvolvimento das raízes tornando as plantas mais suscetíveis a secas e doenças. Nestes solos a calagem é indispensável para cultivos agrícolas. As espécies de plantas do Cerrado toleram altas concentrações de Al e, assim, são fontes de biomoléculas com potencial biotecnológico para a aplicação na obtenção de plantas tolerantes ao Al. O objetivo deste trabalho foi avaliar o mecanismo de tolerância ao Al em espécies arbóreo-arbustivas nativas de uma área de Cerrado, visando apoiar a prospecção de genes e biomoléculas envolvidos com a tolerância ao Al. Foram realizados ensaios histoquímicos com hematoxilina em 31 espécies...

Bacteria with capacities of production of biosurfactants isolated from native plants of Baja California, México Phyton
Méndez-Trujillo,V; Carrillo-Beltrán,M; Valdez-Salas,B; Gonzalez-Mendoza,D.
The aim of the present study was to isolate autochthonous microorganisms with biosurfactants capacities from the rhizospere of the cotton (Gossypium spp.), cachanilla (Pluchea sericea) and salicornia (Salicornia bigelovii) in the Mexicali valley. The biosurfactant activity and biosurfactant productions by the strains isolated from the rhizosphere of the cotton (Bs-Alg), cachanilla (Bs-Cach) and salicornia (Bs-Cach01) were determined using oil spreading technique and emulsifcation activity with corn, olive, soybean and diesel oils, respectively. The analysis of the 16S rRNA showed that strains Bs-Alg, Bs-Cach and Bs-Cach01 are closely related among them and with respect to all Bacillus subtilis with more than 99% similarity values. Results showed that all...

Do Native and Invasive Labels Affect Consumer Willingness to Pay for Plants? Evidence from Experimental Auctions AgEcon
Yue, Chengyan; Hurley, Terrance M.; Anderson, Neil O..
The ultimate objective of commercial horticultural activities is to satisfy the needs of the final consumer. Consumer demand for novel plants drives the ornamental plant industry. Therefore, dispersal of native and invasive horticultural plants can be understood by considering the decisions/choices of consumers who decide which plants to purchase from retailers. In contrast to previous studies on invasive and native plants, this study uses an experimental auction to elicit consumers’ willingness to pay (WTP) for labeled native and invasive attributes. Results from a censored random effect model show that consumers’ WTP for plants decreases when the plants are labeled as invasive and increases when plants are labeled as native. The study finds that...

Are Homeowners Willing to Pay for "Origin-Certified" Plants in Water-Conserving Residential Landscaping? AgEcon
Curtis, Kynda R.; Cowee, Margaret W..
This study investigates the value of local origin-labeling for a nonfood product by evaluating Nevada homeowner purchase propensity for “NevadaGrown” native plants for water-conserving residential landscaping. Homeowner survey results illustrate that homeowners may be willing to pay as much as a 14% premium for origin-certified native plants. WTP estimates are higher when uncertain responses are incorporated into the bidding structure. Preferences for local production and drought resistance in plants are the primary drivers of purchasing decisions in the absence of uncertain responses, while income levels and preferences for natural plant appearance additionally affect purchasing decisions when uncertainty is incorporated.

Lima,Alan D.; Bezerra,Francisco M. S.; Neves,Antônia L. R.; Sousa,Carlos H. C. de; Lacerda,Claudivan F. de; Bezerra,Antônio M. E..
ABSTRACT The objective of this study was to evaluate the growth of forest species under conditions of salinity and water deficit. The experimental design was completely randomized in a triple factorial scheme with four forest species (Neem - Azadirachta indica A. Juss, ‘Aroeira’ - Myracrodruon urundeuva Fr Allemão, ‘Ipê’ - Tabebuia impetiginosa (Mart. ex. DC.) Standl and ‘Sabiá’ - Mimosa caesalpiniifoliaBenth), two salinity levels (1.2 and 8.6 dS m-1) and two water regimes (with and without water restriction). Plant height, stem diameter, number of leaves, shoot dry matter, root dry matter and total dry matter were measured. For all the studied variables, there was statistical significance for the factors species (A) and salinity (B), individually....

Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest Rev. Bras. entomol.
Nuvoloni,Felipe M.; Feres,Reinaldo J. F.; Demite,Peterson R..
Mites associated to Xylopia aromatica (Lam.) Mart. (Annonaceae) in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam.) Mart. (Annonaceae) in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were...
