Bu çalışmada, domateste tuz stresine toleransın sağlanmasında indole-3-acetic acid (IAA) uygulamalarının etkinliği incelenmiştir. Çalışmada materyal olarak TOM-141 (tolerant) ve TOM-139 (hassas) genotipler ile AG5668 domates çeşidi kullanılmıştır. Stres bitkileri için, 3 gerçek yapraklı aşamada (200 mM NaCl) başlanmıştır. Kontrol ise besin çözeltisi sulanmıştır. IAA uygulamalarında stresi birli...

Our objective was to compare some plant growth promoting rhizobacteria (PGPR) properties of Bacillus subtilis and Pseudomonas aeruginosa as representatives of their two genera. Solanum lycopersicum L. (tomato), Abelmoschus esculentus (okra), and Amaranthus sp. (African spinach) were inoculated with the bacterial cultures. At 60 days after planting, dry biomass for plants treated with B. subtili...

The pink hibiscus mealybug (PHM), Maconellicoccus hirsutus (Green) (Hemiptera: Pseudococcidae) and the associated hymenopterous parasitoid, Anagyrus kamali Moursi, 1948 (Hymenoptera: Encyrtidae), are reported for the first time in Brazil. Specimens of the PHM were collected on nine hosts plants, Annona muricata L. (Anonnaceae), Glycine max (L.) Merr. (Fabaceae), Centrolobium paraensis Tul. (Fab...

Studies on the effectiveness of various sterilants and culture conditions on in-vitro seed germination in tomato (Solanum lycopersicum L.) cv. PKM-1 revealed that among three sterilants used, surface sterilization of seeds with 5 % NaOCl for 20 minutes was found to be more effective resulting in high germination rate and contamination free cultures. Similarly among the different media and cultu...
