Tagetes Erecta L

Studies of soil samples from an apple orchard in Frelighsburg revealed the presence of seven species of Endogonaceae, six of which generated vesicular and arbuscular mycorrhizae on Tagetes erecta L. While Glomus constrictum Trappe, Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe, and Sclerocystis rubiformis Gerd. & Trappe made up more than 90% of the organisms observed, Gigaspora calospora (Nicol. & Gerd.) Gerd. & Trappe, Glomus aggregatum Schenck & Smith, and Glomus etunicatum were seen in approximately half of the samples. An enumeration of the Endogonaceae observed is followed herein by a discussion dealing with the frequency and the relative abundance of these species in the soil and with the practical interest which arises from this type of survey.

Every plant rhizospheres in any ecosystem there are various living microorganisms including Arbuscular Mycorrhizae Fungi (AMF).  An isolation and characterization is required to investigate the species or type of the AMF. This research was aimed at studying the isolation and characterization of AMF sporulation in soybean rhizospheres in Jambi Province. The results of evaluation on soil samples before trapping showed that there are spores from three genus of AMF twelve types Glomus , two types Acaulospora and one type of Enthrophospora.  Following single spore culture in soybean rhizosphere, 5 spore types were obtained:  Glomus sp-1, Glomus sp-4, Glomus sp-7, Glomus sp-8 Glomus sp-10.

Abstract Entomopathogenic nematodes (EPNs) are a promising alternative to integrated control in many fruit pests. Few studies were made on the relationship of Anastrepha fraterculus natural population with native EPNs population and other biotic and abiotic factors. The aim of this work was to verify the occurrence of endemic nematodes in an apple orchard, concerning environmental conditions and technical procedure, and access isolates virulence to A. fraterculus larvae. The experiment was conducted during a year taking monthly soil samples from an apple orchard, with and without fallen fruits just above the soil. Samples were baited with Tenebrium molitor and A. fraterculus larvae in laboratory. Canopy and fallen fruits were sampled to access the pest infestation. Seventy three EPN isolates were captured, in 23.2% soil samples, more with T. molitor than with A. fraterculus baits. From the 20 isolates tested against A. fraterculus, only five were pathogenic, and they were identified as Oscheius sp. The nematodes were captured during all seasons in a similar frequency. Soil and weather conditions, presence of fruit over the orchard soil, and A. fraterculus pupae in the fruits had no significant influence on the capture. As a conclusion, nematodes of the genera Oscheius are found in an apple orchard of Porto Amazonas constantly along the year, independently of fluctuations in A. fraterculus population, climate conditions and presence of fruit over the soil. Some of the isolates are pathogenic to A. fraterculus.

ABSTRAK: Pada penelitian ini dilakukan pengembangan formula sediaan hand and body cream dengan memanfaatkan sumber antioksidan yang dimiliki oleh dua jenis ekstrak etanol yaitu ekstrak bunga pacar air merah (Impatiens balsamina L.) dan bunga gemitir (Tagetes erecta L.) dengan taraf perlakuan sebesar 1% dari masing-masing ekstrak (FPM dan FG) dan campuran 0,5% ekstrak pacar air merah dan 0,5% ekstrak gemitir (FCPMG). Pengujian terhadap  produk dilakukan pada sifat fisikokimia  meliputi pH, viskositas, aktivitas antioksidan, angka lempeng total mikroba, dan ukuran partikel. Berdasarkan hasil pengujian produk hand and body cream yang dihasilkan memiliki antioksidan yang cukup tinggi sebagai produk perawatan tubuh dengan penambahan 1% ekstrak etanol pacar air merah, gemitir dan campuran dari kedua ekstrak etanol. Kualitas produk hand and body cream yang dihasilkan baik dan memenuhi standar mutu SNI dari aspek nilai pH, viskositas, dan nilai ALT. Warna yang dihasilkan mulai dari warna kuning kemerahan sampai dengan warna kuning, dan partikel yang dimiliki oleh produk adalah nanopartikel dengan sistem polidispersi. ABSTRACT: Formulations of hand and body creams using ethanol extracts of flowers of red Impatiens balsamina L. And Tagetes erecta L. As antioxidant sources have been developed.  One percent of  extracts (FPM and FG) and the mixture of 0.5% each extracts (FCPMG) were added to the basic formula. The analysis of physicochemical properties of the products was conducted including pH, viscosity, antioxidant activity, the size of the particles, and total microbial plate numbers. Based on the results, the quality of the hand and body creams meet the national standard of Indonesia (SNI) regarding to pH, viscosity, and the total microbial numbers. The colours of the hand and body creams resulted are reddish yellow to yellow with polydispersion nanoparticles.
