Determining the effects of Trichoderma harzianum and some mycorrhizal fungi on plant growth and against Rhizoctania solani Kühn in Lilium under in vivo conditions

Abstract

This study was conducted to determine the effects of microbial fertilizer containing Trichoderma harzianum Kuen 1585 (Tr), biological preparation (BRDI) (containing Glomus aggregatum, G. clarim, G. deserticola, G. intraradices, G. monosporus, G. mosseae, Gigaspora margarita and Paraglomus brasilianum), and Glomus sp. collected from agricultural areas in Aydin province on plant growth in Lilium and Rhizoctonia solani Kühn. (Rs) bulb and root rots under in vivo conditions. Study was conducted in 2 stages: at stage 1, effects of Tr, BRDI and Glomus sp. on growth of lily plants were observed and four treatments, Tr (20 g/kg), BRDI (40 cc/L), Glomus sp. (10 spore/g) and control, took place in this trial. At stage 2; effects of Tr, BRDI and Glomus sp. on Rs were observed and Rs (2%), Rs + Tr, Rs + BRDI, Rs + Glomus sp. and control treatments were used in the study. Treatments at stage 1 had significant effects on flower stalk length, length of flower bud and flower head diameter. Flowers with the longest stalk (62.03 cm) were obtained from control and this was followed by flowers harvested on lily plants treated Glomus sp. Flowers obtained from the bulbs treated Glomus sp., had the highest flower head diameter (15.27 cm). Significantly positive effects were observed on root growth of bulbs obtained from Tr and Glomus sp. treatments. Glomus sp. gave the best result, and disease severity which is 4.73 in Rs was reduced to 1.20 with Glomus sp. Similar results were also obtained in terms of fresh root weight.

Efficacy of bio-control agent on growth and flowering in chrysanthemum (Dendranthema grandiflora Tzvelev) cv. Marigold

“…This may be due to Trichoderma spp. this access nutrients, increased solubility of insolubly compounds as well as increased availability of micronutrients by result of increased plant growth and flower diameter (Altmore et al 1999 and Yedidia et al 2001) [1,32] The results are in conformity with the finding of Anusuya et al (2003) [3] in carnations, Sirin (2011) in lilium, Dubey et al (2008) [8] in gladiolus and (Shrma and Chandel, 2013) in carnation.…”

Synergistic interaction of Glomus mosseae T. and Trichoderma harzianum R. in the induction of systemic resistance of Cucumis sativus L. to Alternaria alternata (Fr.) K.

“…Treating sunflower plants with Glomus sp. and T. harzianum fungi led to increase in the effectiveness of enzymes in defending against pathogens and found that inoculating plants with these bio-agents led to an increase in effectiveness of peroxidase which in turn increases resistance against R. solani (38).…”

Lilyum zambaklarında (lilium sp.) farklı yetiştirme ortamlarının yavru soğan oluşumu ve gelişimi üzerine etkisi

“…Topraklı yetiştiricilikte Rhizoctonia solani, Phytophthora ssp., Fusarium spp., Verticillium spp., Pythium spp., Botrytis sp. gibi toprak kaynaklı hastalık etmenleri başarısızlıklara neden olmaktadır (Miller, 1998;Chase, 2005;Gümrükçü ve Gölükçü 2005;Şirin, 2011). Ancak seralarda yapılan yetiştiricilikte toprakların fiziksel ve kimyasal yapılarının uygun olmaması, monokültür uygulamalar, bilinçsiz gübrelemeler, kimyasal madde kullanımı ve tuzluluğun artması gibi nedenlerle toprak yorgunlukları yaşanması kesme çiçek verim ve kalitesini etkilediği gibi aynı zamanda üretim materyali olan yavru soğan oluşum miktarını ve kalitesini etkilemektedir.…”
