“…Several isolates of Trichoderma has been found to enhance seedling development as it is considered an essential beneficial and biocontrol fungus [12]. A similar work was conducted by Doni et al [13] where the Trichoderma species isolated from corn tested for their potential rice germination and growth. Based on the rice seedling height as a growth parameter, there was a significant increase compared to control indicating that corn likely carries Trichoderma isolates with potential agricultural applications.…”

The testing and use of microorganisms for in vitro growth promotion of agriculturally significant crops such as rice has increased but remains underexploited. The current study aims to explore growth-enhancing mechanisms of dominant root-associated fungi (RAF) isolates from Drynaria quercifolia and test their effects on rice. The most abundant RAF on five tree-collection sites were cultured in vitro. Genomic DNA of the RAF were extracted and the ITS (internal transcribed spacer) region of the 18S ribosomal DNA (rDNA) were sequenced and molecularly identified. Two RAF isolates significantly increased the plant shoot/total length (Meyerozyma guilliermondii: 10.29±4.18/13.46±4.18 cm; Trichoderma simmonsii: 10.33±1.38/13.23+1.58 cm), shoot/total fresh weight (Meyerozyma guilliermondii: 57.33±15.76/71.00±16.10 mg; Trichoderma simmonsii: 63.22±12.23/76.00±10.67 mg) and shoot/total dry weight (Meyerozyma guilliermondii: 16.99±6.74/22.78±7.41 mg; Trichoderma simmonsii: 16.89±3.33/23.11±5.30 mg) weight comparedto the negative control. These results possibly show the ability of the two isolates to produce the hormone gibberellic acid. On the other hand, three of the RAF isolates did not significantly increase seedling growth and biomass. The Trichoderma yunnanense (shoot: 0.36±0.16 cm; total: 0.53±0.20 cm), unidentified Mucoromycotina isolate F5P1RAF16 (shoot: 1.87±0.59 cm; total: 2.12±0.58 cm) and the unidentified Mucoromycotinaisolate F9P2RAF21 (shoot: 3.26±1.56 cm; total: 5.19±2.00 cm) approximated the growth of rice seedlings inoculated with broth and water negative control (shoot: 4.40+2.27 cm; total: 6.38+2.28 cm). This possibly indicates the inability of these isolates to produce GA or their potential ability to produce growth-retarding metabolites. Preliminary data from this study reveal potential growth-promoting capacity of RAF isolates on rice.

“…Three promising Trichoderma isolates were further evaluated at different salinity levels in the pot trial under saline conditions. It was observed that seed biopriming with these plant growth promoting Trichoderma significantly promoted shoot, root, and other growth contributing parameters of maize at all salinity levels both under axenic and pot conditions [31]. Decrease in the shoot and root growth in saline water could be due to reduced photosynthesis and reduced root growth due to salinity and disturbance in mineral supply [32].…”

In the present study, a total of 70 Trichoderma spp. were isolated from the rhizosphere soils of vegetable and spice crops that were grown in Andaman and Nicobar Islands, India. Initial screening of Trichoderma spp. for salt tolerant properties showed 32 isolates were able to tolerate 10% NaCl. Furthermore, these isolates were screened for their potential plant growth-promoting characteristics such as IAA production, phosphate solubilization, and siderophore production. Among 32 isolates, nine isolates were able to produce IAA, siderophore, and solubilize phosphate. Jar trial was carried out on maize under axenic conditions at 1.67, 6.25, 11.25, 17.2, and 22.9 dS m salt stress using the best nine isolates. Three isolates (TRC3, NRT2, and THB3) were effective in improving germination percentage, reducing reduction percentage of germination (RPG) and also in increasing the shoot and root length under axenic conditions. These three isolates were further tested under pot trial at 52 (sea water), 27, 15, 7, and 1.67 dS m . TRC3 was found to be the most effective isolate compared to the other isolates and significantly increased the physiological parameters like shoot, root length, leaf area, total biomass, and stem and leaf fresh weight at all stress levels. Similarly, total chlorophyll content also increased by TRC3 over control. All three isolates, NRT2, TRC3, and THB3 showed lower accumulation of malondialdehyde (MDA) content whereas, proline and phenol content were higher than the uninoculated control plants under both normal and saline conditions. The results suggest that these isolates could be utilized for the alleviation of salinity stress in maize.

“…Availability of Trichoderma to the rice roots significantly enhanced root length and biomass yield and may be attributed to several growth promoting mechanisms like (i) mineral availability, (ii) availability of phytohormones, (iii) release of elicitors etc. ( Doni et al, 2014 ). Plant growth hormones like cytokinins-like molecules, e.g.…”

Salinity stress affected crop production of more than 20% of irrigated land globally. In the present study the effect of different concentrations of NaCl (0, 100, and 200 mM) on growth, physio-biochemical attributes, antioxidant enzymes, oil content, etc. in Brassica juncea and the protective role of Trichoderma harzianum (TH) was investigated. Salinity stress deteriorates growth, physio-biochemical attributes, that ultimately leads to decreased biomass yield in mustard seedlings. Higher concentration of NaCl (200 mM) decreased the plant height by 33.7%, root length by 29.7% and plant dry weight (DW) by 34.5%. On the other hand, supplementation of TH to NaCl treated mustard seedlings showed elevation by 13.8, 11.8, and 16.7% in shoot, root length and plant DW respectively as compared to plants treated with NaCl (200 mM) alone. Oil content was drastically affected by NaCl treatment; however, TH added plants showed enhanced oil percentage from 19.4 to 23.4% in the present study. NaCl also degenerate the pigment content and the maximum drop of 52.0% was recorded in Chl. ‘a’. Enhanced pigment content was observed by the application of TH to NaCl treated plants. Proline content showed increase by NaCl stress and maximum accumulation of 59.12% was recorded at 200 mM NaCl. Further enhancement to 70.37% in proline content was recorded by supplementation of TH. NaCl stress (200 mM) affirms the increase in H2O2 by 69.5% and MDA by 36.5%, but reduction in the accumulation is recorded by addition of TH to mustard seedlings. 200 mM NaCl elevated SOD, POD, APX, GR, GST, GPX, GSH, and GSSG in the present study. Further enhancement was observed by the application of TH to the NaCl fed seedlings. NaCl stress suppresses the uptake of important elements in both roots and shoots, however, addition of TH restored the elemental uptake in the present study. Mustard seedlings treated with NaCl and TH showed restricted Na uptake as compared to seedlings treated with NaCl alone. In conclusion, TH proved to be very beneficial in imparting resistance to the mustard plants against NaCl stress through improved uptake of essential elements, modulation of osmolytes and antioxidants.
