“…Under water stress conditions, AM-colonized plants show enhanced photosynthetic efficiency and thus increase in shoot biomass (Ruiz-Sanchez et al 2010). Higher chlorophyll produce more photosynthate ensured better substrate availability for the growth and development of root system, AM fungi and rhizospheric microflora (Narwal et al 2018). The antioxidant accumulation in plants is taken as an index of tolerance to environmental stress.…”

With the growing concern of water scarcity in agriculture, aerobic rice (Oryza sativa L.) is a promising mode of cultivation for reducing water use, although the reduced optimal plant growth and yield are major constraints. Arbuscular mycorrhiza (AM) are known to readily colonize rice roots under aerobic conditions, however, the response of upland and lowland rice genotypes has not been investigated. This study was carried out during 2018-19 at ICAR-IARI, New Delhi, using a mycorrhizal consortium and percent colonization was observed to be higher by 58% in upland rice genotypes. AM- upland plants also showed 20% higher plant biomass. AM colonization significantly enhanced rice growth under aerobic conditions, with the upland rice genotypes. Pyari and Satyabhama showed higher response upon AM inoculation. AM colonization increased the total chlorophyll by 54% and the upland rice genotypes showed 51% enhanced nitrogenase activity in their root zones, with highest recorded for Satyabhama. The AM plants showed enhanced activities of nitrate reductase (NR) and glutamine synthetase (GS), and interestingly, the rice genotypes with higher NR and GS (Pyari, Satyabhama) also exhibited more (20%) biomass production and plant N content (36%). Significant varietal differences were recorded in terms of accumulation of antioxidant compounds such as ascorbate, glutathione and proline in AM inoculated plants, which helped to alleviate negative effects of water stress in rice plants under aerobic cultivation.

“…They further claimed that double dose was the most effective treatment which increased the plant growth and root weight. Narwal et al (2018) demonstrated the favorable effects of micorrhizal association in rice plants under aerobic conditions and showed positive correlation with the total chlorophyll content and nitrate reductase activity. The present investigation aims to assess genetic diversity amongst five different germplasm of ashwgandha, W. sominifera on the basis of their phenotypic and biochemical characteristics and to study the mycorrhizal effect on these features.…”

Mycorrhizal inoculation in the plant causing increase in growth and production of phytochemicals is well reported, however little information is available related to the effect of mycorrhiza on morphological and biochemical properties of the medicinal plants like Ashwagandha. The present study is an attempt on diversity analysis in Withania somnifera with an aim to ascertain the nature and extent of genetic diversity present among different accessions in presence of mycorrhiza. The major biochemical constituents of Ashwaganda roots are with nolides which are well known for its medicinal properties. Mycorrhizal associations confer benefits like better nutrition acquisition, enhanced growth, defense enhancement and improved abiotic and biotic stress tolerance in plants. The present investigation was undertaken to assess genetic diversity among five different accessions of W. somnifera using morphological and biochemical markers and the effect of mycorrrhizal inoculation on these marker. The present study concluded that presence of mycorrhiza was effective on plant growth and phytochemical constituents more than non-treated plants. Amongst five selected germplasms IC 283662, JA 134, RAS 23, MPAS 6 and MWS 205 of W. somnifera, JA 134 showed best response in pretext of the selected morphological and biochemical features in presence of mycorrhiza.

“…The exploration of mycorrhizal symbiosis is one of the most promising methods for creating resource-efficient and resilient agricultural systems [ 20 , 22 ]. Several studies have reported AMF diversities in rice [ 23 , 24 , 25 ], but very limited information is available on their performance in aerobics under P-deficient conditions [ 26 ]. Additionally, some studies indicated that AMF have a host preference [ 27 ] and their performance will vary depending on different agroecosystems [ 28 ].…”

The prominence of arbuscular mycorrhizal fungi (AMF) in sustainable rice production has long been recognized. However, there is little information about AMF response in aerobic rice cultivation under phosphorus (P)-deficient conditions. The aim of this experiment was to compare and determine the preeminent AMF effects on rice mycorrhizal colonization, responsiveness, P utilization, and different growth-promoting traits under P-deficient conditions. Different AMF genera viz. (Funneliformis sp., Rhizophagus sp., Glomus sp., Acaulospora sp., and Claroideoglomus sp.) in four different aerobic rice varieties developed by ICAR-NRRI, India (CR Dhan 201, CR Dhan 204, CR Dhan 205, and CR Dhan 207) were investigated using the check P-susceptible variety (IR 36) and the P-tolerant variety (Kasalath IC459373). Data analyzed through linear modeling approaches and bivariate associations found that AMF colonization was highly correlated with soil enzymes, particularly fluorescein diacetate (FDA) and plant P uptake. The microbial biomass carbon (MBC) and FDA content were significantly changed among rice varieties treated with AMF compared to uninoculated control. Out of four different rice varieties, CR Dhan 207 inoculated with AMF showed higher plant P uptake compared to other varieties. In all the rice varieties, AMF colonization had higher correlation coefficients with soil enzymes (FDA), MBC, and plant P uptake than uninoculated control. The present study indicates that AMF intervention in aerobic rice cultivation under P-deficient conditions significantly increased plant P uptake, soil enzymes activities and plant growth promotion. Thus, the information gathered from this study will help us to develop a viable AMF package for sustainable aerobic rice cultivation.
