Curvas pressão-volume e expansão foliar em cultivares de algodoeiro submetidos à défcit hídrico

open access: yesScientia Agricola, 1999
Foi avaliado o comportamento de dois cultivares de algodoeiro em resposta ao déficit hídrico, utilizando-se a expansão foliar como parâmetro discriminatório, bem como a metodologia das curvas pressão-volume para comparar suas habilidades com relação ao ...

Osmotic adjustment in wheat leaves as a function of soil water levels and growth stages

open access: yes, 2014
The effects of three levels of water in the soil (35%, 65% and 95% of the total volume of pores taken by water) before and after severe water stress were studied in three cultivars of wheat (Triticum aestivum L.) (IAC-18: Xavantes; IAC-21: Iguaçu; and ...

Relações hídricas Internas da soja sob déficit hídrico em condições de campo

open access: yes, 2014
Soybean plants (Glycine max) cv. Doko were subjected to different soil drying cycles and rewetting. Using the pressure-volume curve method, the osmotic potential at full turgor (4,7 l 00) and water potential at zero turgor (4,0) were measured.
