Effects of foliar application of glycine betaine and chitosan on Puccinellia distans (Jacq.) Pari, subjected to salt stress.

2019

Introduction:Using brackish water for irrigation may expose turfgrasses to salinity stress.Employing the best treatments to maintain high-quality turfs under saline conditions is animportant requirement for turfgrass management.Methods:We tested the response of ahalophyte grass,Puccinellia distans, to irrigation with saline solutions and to foliarapplication of two osmoprotectants, such as glycine betaine (GB) or chitosan (CH). Plantswere grown in pots under controlled conditions and irrigated with 200 mM or 600 mM ofNaCl solutions. The response to salinity treatments and osmoprotectant application wasevaluated after 90 days by measuring leaffiring, leaf density, shoot length and biomass, r…

Effect of salinity on Puccinellia distans (L.) Parl. treated with NaCl and foliarly applied glycinebetaine

2009

Turfgrasses general appearance is much affected by environmental stresses because the species used for this purpose are particularly exigent in terms of technical inputs and water need. In the Mediterranean area, sometimes irrigation is provided by using waste water which may contain high concentrations of dissolved salts which can cause salt stress injury and poor turf quality. Puccinellia distans (L.) Parl. is a halophyte cool season grass that seems to have a high salinity tolerance when cultivated in sodic soils or in NaCl-rich hydroponic cultures. We investigated the response of P. distans to salinity in a soil culture in a controlled growth environment. The effect of different concent…

Effectiveness of glycinebetaine foliar application in relieving salt stress symptoms in two turf-grasses

2014

Salinity is one of the problems that has to be dealt with in turf-grass management, due both to restrictions in freshwater use for landscape irrigation and exposition to salt stress in coastal areas. This has led to the need to select salinity tolerant genotypes and test management practices, such as the application of osmoprotectants, in order to maintain turf quality at acceptable costs. We compared the effects of irrigation with 600 mM NaCl and glycinebetaine (GB) application for 8 weeks on pot-grown weeping alkaligrass (Puccinellia distans (L.) Parl.) and tall fescue (Festuca arundinacea Schreb.). We selected two easily assessable parameters, total clippings fresh weight and chlorophyll…
