Correlation between thrips tabaci attack degree and morphological features of Calendula officinalis L. flowers.
Research Journal of Agricultural Science, 2012Co-Authors: Cristina Coradini, Irina Petrescu, V. Tabără, R. CoradiniAbstract:The marigold is a very ornamental plant that is commonly grown in the flower garden, and occasionally as a culinary herb. Marigolds had an important economic values, its cropping knew a continual increase in the last years thanks to its usage in a more and more large area in the pharmaceutic and cosmetic domain. Thrips tabaci are feeding drains underlying cells, leaving air- filled spaces which impart a silvery sheen and cause distortion during growth and reduction in photosynthetic capacity. In the West Plain of the country relative existed a few investigations about that pest attack on the marigolds crop, an important crop both from medical point of view and culinary point of view. The purpose of that work was to determine the correlation of pests attack degree and flowers diameter to 10 local population of Calendula officinalis L. from Arad district. In the thrips experiments, the results showed that flowers with bigger attack degree were smaller compared to flowers with smaller attack degree. This difference in flower diameter was due to deformations of the flowers and was more pronounced at a bigger density of common thrips. The flowers deformation and its decrease in diameter implied also the production increase, but the obtained quantity of flowers was lower. The results obtained through correlation between Thrips tabaci attack degree and morphological features of Calendula officinalis L. flowers permitted the identification of frequency and intensity of attack, and connection between them and density of the pest. Accordingly, tobacco trips produced great damages in Calendula officinalis L. crop depreciating from a qualitative point of view, the diminution and bending flowers diameter and qualitative speaking the production decreased. The present paper belongs to a big work which had like study "Resistance testing of some species of Calendula officinalis L. to Thysanoptera pest attack through different methods/techniques of analysis concerning the improvement of raw material quality", that represented the theme of postdoctoral-dissertation.

THE RESPONSE OF DIFFERENT LOCAL POPULATIONS OF Calendula officinalis L. TO THRIPS TABACI ATTACK
Research Journal of Agricultural Science, 2012Co-Authors: Cristina Coradini, Irina Petrescu, V. Tabără, Lavinia Madalina Micu, R. Z. BejanAbstract:Marigold is one of the best known and versatile herbs in herbal medicine and is also a popular domestic remedy. The thrips can cause serious damages and they also represent the main vectors of viruses. That is why one of the objectives of this study is to analyze their response to Thrips tabaci attack. In purpose of identification attack frequency, attack intensity and attack degree it had been study 20 of local population of Calendula officinalis L. from diffrent localities of Caras- Severin district. In Romania relatively realised a few investigations concerning response of Calendula crops to Thrips tabaci attack. Being a success the ones mentioned, it was assessed to make some complex investigations for teoretical argumentation and methods advancement used in identification of common thrips attack degree, which constituted an actual matter for our country concerning the best moment of treatments applying in the crop flowers to obtain a high production and of superior quality, because that medical plant was one of those plants appreciated for its therapeutic qualities based on complex of active biologic substances. From among all local population, 20 (representing 100%) have been attacked. Even if 10 local population have provided statistical differences for the serious attack frequency and eight for intensity of the attack, only two of these have provided statistical differentiations for attack degree. The results demonstrate that thrips are pests that occur in the culture of Calendula officinalis with significant frequency, intensity and attack degree. The local population really influences the attack, some of them being registered with small attack signs, while others were obviously preferred by pests. The results obtained through the attack of frequency and intensity identification to local populations of Calendula officinalis L.it had permitted the attack degree of tobacco trips in the marigolds' crop from the western part of the country. The present paper belongs to a big work which had like study "Resistance testing of some species of Calendula officinalis L. to Thysanoptera pest attack through different methods/techniques of analysis concerning the improvement of raw material quality", that represented the theme of postdoctoral- dissertation.

Controversial effects of Calendula officinalis L. on Biochemical and Pathological Factors of Nephropathy in Diabetic Wistar Rats
Avicenna Journal of Medical Biochemistry, 2015Co-Authors: Iraj Salehi, Shirin Moradkhani, Amaneh Mohammadi Roushandeh, Hamideh Nazari, Alireza Pouyandeh RavanAbstract:4 Objectives: The purpose of the present study was to evaluate the effect of the hydroalcoholic extract (300 mg/kg) of Calendula officinalis (marigold) on blood biochemical profiles and histopathological changes in kidney of streptozotocin-induced diabetic rats. Materials and Methods: Twenty male Wistar rats were divided to four groups: Normal control (NC), diabetic control (DC), normal C. officinalis (N+CO) 300 mg/kg, and diabetic C. officinalis (D+CO) 300 mg/kg. The rats were treated for a period of 13 weeks. Diabetes was induced by Streptozocin injection, intraperitoneally. Level of glucose, urea, creatinine and also total anti-oxidant capacity, malondialdehyde, total oxidant status in serum and histological alterations in the kidney were analyzed. Results: Level of serum glucose, urea, creatinine, malondialdehyde and total oxidant status were increased in diabetic rats, whereas, total anti-oxidant capacity was decreased compared to the control animals. Also, histological findings confirmed the absence of integrity in glomerulus and mass infiltration in kidney tissue in diabetic rats compared to the normal controls. Calendula officinalis extract had no effect on blood glucose, but it decreased blood urea nitrogen and creatinine, total oxidant status and malondialdehyde while it increased total anti-oxidant capacity in the diabetic extract-treated group when compared to diabetic rats. Calendula officinalis could not prevent nephropathy changes in the diabetic rats. Conclusions: Therefore, our results suggest that although administration of 300 mg/kg of Calendula officinalis extract showed salutary effects on anti-oxidant profile, yet its protective effects on anti-diabetic and regenerative properties on nephropathy were ambiguous and require more investigations.
