1. Viability of Italian ryegrass (Lolium multiflorum) seeds under application of synthetic auxin herbicides
ABSTRACT Italian ryegrass (Lolium multiflorum) is one of the main weeds in the wheat crop, and the application of synthetic auxin herbicides has the potential to reduce seed viability, therefore, restricting the input into the seed bank. The objective was to evaluate the effects of synthetic auxin herbicides applied at different growth stages on germination,

2. Rooting potential of grapevine rootstocks cuttings
ABSTRACT The objective of this work was to evaluate the rooting potential and propagation of seventeen grapevinevine rootstocks. The experiment was carried out in the municipality of Canoinhas - Santa Catarina, in 2018 and 2019. Woody canes from the grapevine rootstocks 99R, 110R, 420 A Mgt, 101-14 Mgt, IAC 766, IAC 313, IAC 572, Courdec 3309, Freedom, Grave

3. Phytotoxicity and physiological changes in Schinus terebinthifolius Raddi under simulated 2,4-D drift and dicamba
ABSTRACT The use of auxin mimics herbicides in agriculture is widespread in a great diversity of crops. The indiscriminate use of herbicides can cause adverse effects in the plants. Among the plant species that stand out for being highly competitive and resistant to biotic and abiotic stresses, it is the brazilian peppertree (Schinus terebinthifolius Raddi.)

4. CYTOKININ AND AUXIN INFLUENCE ON GROWTH AND QUALITY OF WATERMELON IRRIGATED WITH SALINE WATER
RESUMO A melancia apresenta grande relevância econômica, no entanto, fatores edafoclimáticos e manejo inadequado vem favorecendo a salinização da água utilizada para irrigação, sendo este um fator limitante para o crescimento e produção da cultura. Contudo, considera-se que a utilização de reguladores de crescimento pertencentes ao grupo das cito

5. Application time affects synthetic auxins herbicides in tank-mixture with paraquat on hairy fleabane control
ABSTRACT Conyza sp. was the first glyphosate-resistant weed in Brazil’s soybean crop. Synthetic auxin herbicides followed by paraquat has improved the hairy fleabane control, and time of day of herbicide application can affect the control efficacy. There are no studies reporting the effects of the application time of synthetic auxins in tank-mixture with p

6. Phytopathogen resistance of phytohormone-deficient and low-sensitivity mutant tomatoes
ABSTRACT This study broadens the knowledge of plant-pathogen interactions using phytohormone-deficient and low-sensitivity mutant tomatoes. The experiment was performed under greenhouse conditions and the mutants used were provided by the HCPD laboratory, at ESALQ/USP. The hormone mutant Never ripe showed a larger final lesion size when inoculated with Botry

7. MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
ABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seed

8. SYNTHESIS AND PHYTOTOXIC PROFILE OF A NEW TETRAOXANE DESIGNED FROM A COMMERCIAL AUXIN
Modern agriculture relies on the massive use of agrochemicals, including herbicides. Despite their effectiveness, a continuous use of herbicides sharing the same target has resulted in the selection of weed biotypes resistant to such chemicals. To cope with this problem, the development of new herbicides is an urgent requirement. In this work we applied the

9. VITRO OF Melanoxylon brauna SCHOTT. MORPHOGENESIS: RESPONSIVENESS OF EXPLANTS TO PERMANENT AND TEMPORARY IMMERSION GROWTH REGULATORS
ABSTRACT Melanoxylon brauna is propagated by seeds, however, low yield, pest attack and short viability are problems in seedling production. In vitro cultivation is an alternative for large-scale seedling production, but studies with this species are scarce. The aim of the work was to analyze the in vitro morphogenesis of braúna. Explants after induction of

10. Anatomical and histochemical studies of the somatic embryogenesis of Syagrus oleracea from immature inflorescences
Abstract Anatomical and histochemical studies were carried out during the somatic embryogenesis of Syagrus oleracea (Mart.) Becc. from immature inflorescences. Immature rachillas were inoculated on Murashige and Skoog medium with 4.52 μM 4-amino-3,5,6-trichloropicolinic acid (Picloram) and 2,4-diclorophenoxyacetic acid. Auxin concentrations were gradually r

11. Physalis angulata L. propagation in vitro
ABSTRACT Physalis angulata L. is a plant with great fruit production potential, mainly in family farms, due to its versatility and valuable products such as jellies and juice concentrates. The aim of the present study is to evaluate the effect of two cytokines - i.e., plant growth regulators 6- benzylaminopurine (BAP) and kinetin (KIN) -, in association, or

12. Propagação de jamboleiro [Syzygium cumini (L.) Skeels] por alporquia
Resumo O jamboleiro propaga-se geralmente por sementes, sendo este método inviável, devido aos problemas de segregação genética e pelo longo período que as plantas levam para alcançar a idade reprodutiva. Desta forma, o desenvolvimento de protocolo para propagação vegetativa desta espécie por meio da alporquia se torna alternativa importante a ser
