“…Low Salinity inhibits hybrid pennisetum (Pennisetum americanum × Pennisetum purpureum) growth, photosynthesis, soluble sugar content, and more, but adverse effects were reduced by applications of nitrate up to 5 mmol/L [147]. The same hybrid can exclude salt from new leaves, but salinity levels of 100 mM results in shoot fresh and dry weight reductions of 50 % compared to controls [146].…”

Stress-Tolerant Feedstocks for Sustainable Bioenergy Production on Marginal Land

Given the mandated increases in fuel production from alternative sources, limited high-quality production land, and predicted climate changes, identification of stress-tolerant biomass crops will be increasingly important. However, existing literature largely focuses on the responses of a small number of crops to a single source of abiotic stress. Here, we provide a much-needed review of several types of stress likely to be encountered by biomass crops on marginal lands and under future climate scenarios: drought, flooding, salinity, cold, and heat. The stress responses of 17 leading biomass crops of all growth habits (e.g., perennial grasses, shortrotation woody crops, and large trees) are summarized, and we identify several that could be considered "all purpose" for multiple stress types. Importantly, we note that some of these crops are or could become invasive in some landscapes. Therefore, growers must take care to avoid dissemination of plants or propagules outside of cultivation.

“…Some potential biomass crops, such as Pennisetum purpureum, show no more salinity tolerance than conventional agricultural crops [146,147]. Thus, the current challenge is to find biomass crop species that can grow and maintain high yields on marginal salt-affected soils.…”
