Historical and ethnobotanical aspects of domestication in Tagetes. For Tagetesthere are a few reports related to methods of sexual and asexual propagation Ferreira et al. Another possible explanation for this result is that marigold plants could produce repellent volatiles to thrips, including T.
Mixtures of coal ash and compost as substrates for high bush blueberry. Ediciones Mundi Prensa, Madrid. In cultvio previous study, several non-domesticated wild species of the genus Lippia from Brazil L. Accordingly, the species L. Chemical variation in essential oil profiles detected using headspace solid-phase microextraction gas chromatography spectrometry in response to potassium, nitrogen, and water available to micropropagated plants of Salvia stenophylla Burch.
As stated by Visserphytophagous insects respond to a complex mixture of plant odors to recognize their hosts. Biological control of insect pests in the Tropics. Parasitoid abundance, in general, was very low in onion plants, but much lower far from the marigold strip Table 1. In spite of these similarities, the main phytophagous species collected, T. The Interpretation of ecological data: Germination of Tagetes minuta L. In general, the average rooting percentage observed for the two evaluated accessions of L.
For the determination of these parameters, arthropods presenting very low occurrence one or two individuals during the entire sampling period tagefes not included in analysis.
Stock plants were established from seeds collected from mature plants growing wild. This is confirmed by the similarity index between onion and marigold collections Table 2which tagstes For the Lippia genus, in vitro micropropagation protocols have been reported that manage the production of plants with chemical profiles identical to plants normally propagated Gupta et al.
Lippia dulcis shoot cultures as a source of the sweet sesquiterpene hernandulcin. The cuttings were immersed for 5 min in liquid solution at different concentrations of the hormone indolebutyric acid IBA and were subsequently planted in germination trays with 24 wells, with dimensions of 5.
Cultivo del marigold: efecto en el control de nematodos
Horticultura Brasileirav. Figure 2 compares the overall development of the evaluated accessions of L.
Revista Brasileira de Entomologiav. Direct differentiation of shoot buds in leaf segments of white marigold Tagetes erecta L. Auxin effects on root regeneration of scarlet oak seedlings. Conclusions The rooting of tagetfs of L. The same test was performed in germination trays with peat TRM7, with two replicates of 50 seeds, arranged in a greenhouse. Micropropagation of Lippia junelliana Mold. For IBA concentration, there were significant differences for the variables rooting, root length and root dry weight for the different concentrations tested Tab.
Certain flavonoids have been found to act as auxin transport inhibitors that participate in regulating auxin flow in plant tissues Wasson et al.
In vitro micropropagation of Lippia alba. The establishment of propagation and micropropagation techniques for aromatic species that show promise as potential new crops is important in order to ensure rapid reproduction to provide enough material for taegtes high demand that can be generated in a production chain. Phytophagous insect abundance, however, was greater far from than near to marigold strips, Sales Da Silveira, A.
Annual Review of Entomologyv. In general, this species registered the highest values for root length, number of roots and root erectq weight among all the species analyzed and in the Taegtes substrate Tab. In Vitro Propagation of endangered Lippia filifolia Mart. Besides these indices, collection curves were calculated for onion samples Magurran, This indicates a beneficial effect of marigold on the onion field, especially on the dynamics of the arthropod species, which varies as onion plants are collected from more distant marigold plants.
Marigold (Tagetes erecta L.) as an attractive crop to natural enemies in onion fields
Pest management in organic onion farming is based on plant extracts with dr effects. Marigold Tagetes erecta L. Accumulation of endogenous auxins may be due to two major factors: The latter variable determines the number of seeds germinated at intervals of seven d and its numerical value was estimated according to Moreno et al.
Detection of differences among assemblages of marine benthic species based on an assessment of dominance and diversity. Since the phytophagous species involved are not potential pests to onion plants, their population maintenance in the system is not likely to have the associated negative impact of increasing crop herbivore. The reports indicate that the seeds of L.
Thiophene occurrence in different Tagetes species: Ecological diversity and its measurement. Longer roots and larger root dry weight were also observed in the absence of hormone, but a larger number erceta roots was observed when the hormone was applied.
