Abstract Background This study was conducted to assess the effectiveness of plant growth-promoting microbes on foliar disease organic tomatoes under protected cultivation. The biological control agents, viz., Trichoderma harzianum ( T. ), Bacillus subtilis B. and Pseudomonas fluorescens P. ) , used seed treatment, seedling dip, spray separately in sequence with plot size (2.5 × 1 m) spacing (45...

Eucalyptus cultivation has expanded considerably in Brazilian systems, leading to the current search for technologies to optimize growing conditions and the production of seedlings in nurseries. Based on the understanding that the development of tree species such as Eucalyptus sp. can be influenced by endophytic fungi that act directly as plant growth-promoting species, cloned seedlings of Euca...

A method of in vitro clonal propagation of cowslip Primula veris L. (Primulaceae) is reported. This is a species of medicinal importance, protected by law in Poland. MS medium Murashige and Skoog (1962) with 6 benzyladenine BA (4.44 μM) and 2,4-dichlorophenoxyacetic acid 2,4-D (1.13 μM) was found to be optimal for in vitro cowslip propagation from shoot tips under the conditions of culture.
