Species richness and Shannon’s diversity index were higher at 5 m from marigold.

The higher percentage of rooting observed in this study in the absence of exogenous hormone could be due to the accumulation of endogenous auxins that promote root initiation Casimiro et al. Estudios preliminares para el establecimiento del cultivo de Tagetes lucida Cav on line.

Due to the low perceptibility and complexity of seed selection and management in these species, the propagation methods used for evaluation were vegetative asexual reproductionexcept for the species T.

Journal of Natural Historyv. 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 the high demand that can be generated in a production chain.


This indicates that a major number of natural enemy species uses tgaetes marigold strip during more time than the herbivores do, witch is interesting for biological control.

Lippia origanoides chemotype differentiation based on essential oil GC-MS and principal component analysis. Propagation of Atlantic white cedar by stem cuttings.

Plant Cell 18, Besides these phytophagous species, the sucking hemipteran Nysius sp. Stock plants were established from seeds collected from mature plants growing wild. IBA-induced changes in antioxidant enzymes during adventitious rooting in mung vean seedlings: The marigold strips were also sampled during the period of onion cultivation, and each sample corresponding to one square meter of crop coverage, using the same methodology as for onion plants.

Geographic location and conditions of the experiment The propagation and evaluation were carried out in greenhouse conditions at the facilities of the Universidad Tageres de Colombia, Bogota, located at 2, m a. The role of H2O2. One consequence of this is the low participation of Colombia in the global market for aromatic plants. Historical and ethnobotanical aspects of domestication in Tagetes.

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 Cuptivo stenophylla Burch. Flavonoids and auxin transport: Composition of the essential oil from leaves of Tagetes zipaquinensis Hump. In summary, both the substrate fine coconut fiber and the non-application of IBA Tab.

For natural enemies these values are low The treatments consisted of etecta hybrid varieties and two varieties of open pollination, constituting the plots, in four planting densities 0,10m; 0.

Data from onion samples were taken at 5 m and 30 m from the tagetess strip Figure 1. This is due to a higher number of T.

Moreover marigold plants host other phytophagous species that are alternative prey for entomophagous species. Salud UIS 41, This is an indication that few phytophagous species were found at both plant species, except for A. Fitopatologia Brasileirav. Coconut fiber is a substrate with good buffering and high water retention capacities, which are useful for reducing the frequency of irrigation; and tagrtes a low bulk density Quintero et al.

Orius insidiosus as biological control agent of thrips in greenhouse chrysanthemums in the tropics. The performance of L. Parasitoid abundance, in general, was very low in onion plants, but much lower far from the marigold strip Table 1.


Among the insect pests causing yield losses in onion production in Brazil, the onion thrips, Thrips tabaci Lind. This is in accordance with previous observations.

Entomologia Experiementalis et Applicatav. Concluded that as smaller the number of flowers, larger taegtes individual weight, with larger consequent production of petals for flower. We performed an ANOVA with the average calculated over seven weeks of sampling, showing patterns of weekly abundance but performed statistical analysis for the whole period of the experiment. These percentages of germination are relatively high when compared with germination in other wild species of the genus, such as Tagetes lucida, which presents a large number of sterile seeds Acosta de la Luz et al.

How to cite this article. Accordingly, the species L. In a previous study, several non-domesticated wild erecfa of the genus Lippia from Brazil L.

Eighteen taxa 5 m from marigold and only ten 30 m from marigold plants were found, as well as nearly twice as many natural enemies near to as far from marigold strips, 0. Conclusions The rooting of cuttings of L.

Similar tests should be performed to identify this possibility in relation to T. The same test was performed in germination trays with peat TRM7, with two replicates of 50 seeds, arranged in a greenhouse.

Certain flavonoids have been found to act as auxin transport inhibitors that participate in regulating auxin flow in plant tissues Wasson et al.
