Growth and anatomical adaptations in response to salinity stress in Cucurbita moschata Duchesne ‘Butternut’ (Cucurbitaceae)

Pumpkin or squash is an economically important crop that is moderately sensitive to salinity but how its growth is affected by soil salinity is poorly understood. Salinity stress on physiological and anatomical traits of Cucurbita moschata ‘Butternut’ was investigated under hydroponic culture using...
