| ABSTRACT This study aimed to evaluate the agro-economic efficiency of agrosystems of two croppings of arugula (A) and two of lettuce (L) intercropped with carrot (C) under different biomass amounts of roostertree incorporated into the soil and population density proportions between the component crops. The experimental design was a randomized block with four replications, with the treatments arranged in a 4 × 4 factorial scheme. The first factor was made up of the amounts of roostertree biomass incorporated into the soil (10, 25, 40 and 55 t ha-1 on a dry basis) and the second factor by the population density proportions of the component crops in the polycultures (50A-50C-50L%, 40A-50C-40L%, 30A-50C-30L% and 20A-50C-20L% of the population recommended for... |

| O uso de espécies espontâneas da Caatinga como adubos verdes é uma técnica de manejo alternativa para a produção de hortaliças no Nordeste do Brasil, mas ainda escassas são as informações. O presente trabalho foi realizado de outubro a dezembro de 2009 em Mossoró-RN com o objetivo de avaliar o efeito de três espécies espontâneas da Caatinga em diferentes doses de biomassa nos atributos microbiológicos do solo e na produtividade do rabanete. O delineamento experimental foi em blocos casualizados com três repetições, sendo os tratamentos compostos de três espécies da Caatinga [jitirana (Merremia aegyptia); mata-pasto (Senna uniflora) e flor-de-seda (Calotropis procera)] utilizadas em cinco doses de massa seca (5,4; 8,8; 12,2; 15,6 e 21,0 t ha-1). As... |

| The cytotoxic potential of stem organic extracts from Calotropis procera (Asclepiadaceae) was firstly evaluated against cancer cell lines by MTT assay. Subsequently, samples considered cytotoxic were tested for antimitotic activity on sea urchin egg development and for in vivo antiproliferative activity in mice bearing Sarcoma 180 tumor. Among the five extracts (hexane, dichloromethane, ethyl acetate, acetone and methanol), ethyl acetate and acetone extracts displayed higher cytotoxic potential against tumor cells, with IC50 ranging from 0.8 to 4.4 μg/mL, while methanolic extract was weakly cytotoxic. Cytotoxic extracts also exhibited cell division inhibition capacity by antimitotic assay, revealing IC50 values lower than 5 μg/mL. In the in vivo antitumor... |

| Latex is an endogenous milky fluid synthesized and accumulated under pressure in a network of laticifer cells. In this study, latices from five plant species were examined for deterrent effect on oviposition of two Coleoptera (Bruchidae) pests. The latex from Euphorbia tirucalli, Calotropis procera and Plumeria rubrae exhibited deterrent activity on oviposition of both Callosobruchus maculatusand Zabrotis subfasciatus beetles. The latex from Cryptostegia grandiflora and Himathantus drasticus were less effective to C. maculatus and Z. subfasciatus oviposition, respectively. Eggs laid on latex-treated seeds were not affected.The emergence and the mean time of development and weight of larvae grown in treated seeds were similar to the controls. The deterrent... |

| The Calotropis procera seed fibers provide an excellent model system to study the genes involved in fiber elongation, fineness and strength. Expansins constitute one of the important gene families involved in plant cell expansion and other cell wall modification processes. Four homologs of Expansin A gene i.e. CpEXPA1, CpEXPA2, CpEXPA3 and CpEXPA4 were isolated from the cDNA library obtained from fast growing Calotropis procera fibers. These homologs represented typical Expansin A family. Each of them had two conserved domains including GH45 like domain and the putative polysaccharide binding domain. The deduced amino acid sequences of the homologs indicated three conserved motifs: i) eight cysteine residues at N-terminus, ii) four tryptophan residues at... |

| The role of methanolic leaf extracts of Calotropis procera in phenytoin-induced toxicity on histomorphometric variables in the postnatal developing cerebellum of Wistar rat was studied. Pregnant rats were treated orally with 50 mg/kg phenytoin in pre and post natal life and 300 mg/kg methanolic leaf extract of Calotropis procera 1 hour prior to phenytoin administration. 200 mg/kg vitamin C (standard antioxidant) was also administered orally 1 hour prior to phenytoin treatment. The control animals received water. Standard diet of rat pellets and water were provided ad libitum. At the end of the experiment, the offspring of days 1, 7, 14, 21, 28 and 50 post partum, five per group were sacrificed by cervical dislocation. The cerebellum of all groups were... |

| ABSTRACT For the simultaneous achievement of productivity in beet and cowpea associations, it is necessary to take into consideration the choice of cultivar combinations that offer a response in terms of production, product quality and efficiency of the intercropping. Thus, the objective of this work was to evaluate the viability of production of beet cultivars combinations with cowpea cultivars in two cropping years (2016 and 2017) in a semi-arid environment. The treatments arranged in a 2 x 4 factorial scheme, with four replications, consisted of the combination of two beet cultivars (Early Wonder and Fortuna) with four cowpea cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba and BRS Itaim), in addition to monocultures of these cultivars, as an... |

| ABSTRACT Intercropping systems of cowpea with radish are beginning to be deployed in the semiarid region of Rio Grande do Norte state. The great challenge is to know whether or not there is productive efficiency in these systems when fertilized with organic matter produced by spontaneous species from the ‘Caatinga’ biome. Thus, the aim of this study was to evaluate the productive performance of cowpea-radish intercropping systems under different amounts of rooster tree biomass incorporated into the soil. The study was conducted at the experimental farm Rafael Fernandes, rural zone of Mossoró, RN, in the period from June to September 2013, in an experimental design of randomized blocks with four treatments and five replicates. The treatments consisted of... |
