To assess family differences in response to drought, various water potential components of seedlings from six half-sib families of shortleaf pine (Pinusechinata Mill.) were compared under control (well-watered) and drought conditions. Drought stress resulted in significant changes in water relations parameters of the seedlings between treatments and among families. Although both Montgomery (103) and Pope (322) families had a superior capacity to adjust osmotically to both treatments, Montgomery (103) family exhibited greater potential to adapt to droughty environments through having the lowest values of osmotic potential both at maximum turgor and at the turgor loss point and having the highest values of (i) mean volume of osmostic water at the turgor loss point per volume of symplasmic water, (ii) symplasmic water volume per total shoot water volume, (iii) maximum bulk elastic modules, and (iv) turgor potential. Families Polk (115) and Scott (202) showed intermediate responses to drought. Both Scott (219) and Yell (342) families showed the lowest ability for osmotic adjustment to both treatments, but Yell (342) family revealed even lower drought resistance responses. Results from this study may provide the means of screening families that have high drought resistance potential during the field establishment period.

Understanding the mechanisms of plant tolerance to osmotic and chemical stress is fundamental to maintaining high crop productivity. Soil drought often occurs in combination with physiological drought, which causes chemical stress due to high concentrations of ions. Hence, it is often assumed that the acclimatization of plants to salinity and drought follows the same mechanisms. Grass pea (Lathyrus sativus L.) is a legume plant with extraordinary tolerance to severe drought and moderate salinity. The aim of the presented study was to compare acclimatization strategies of grass pea seedlings to osmotic (PEG) and chemical (NaCl) stress on a physiological level. Concentrations of NaCl and PEG were adjusted to create an osmotic potential of a medium at the level of 0.0, −0.45 and −0.65 MPa. The seedlings on the media with PEG were much smaller than those growing in the presence of NaCl, but had a significantly higher content percentage of dry weight. Moreover, the stressors triggered different accumulation patterns of phenolic compounds, soluble and insoluble sugars, proline and β-N-oxalyl-L-α,β-diamino propionic acid, as well as peroxidase and catalase activity. Our results showed that drought stress induced a resistance mechanism consisting of growth rate limitation in favor of osmotic adjustment, while salinity stress induced primarily the mechanisms of efficient compartmentation of harmful ions in the roots and shoots. Furthermore, our results indicated that grass pea plants differed in their response to drought and salinity from the very beginning of stress occurrence.

to test the Effect of elevated temperature and drought stress on growth of Lycium barbarum, the one-year-old seedling of L. barbarum were planted in ambient temperature condition or elevated temperature (2.5~3.7°Cabove ) condition using open top chambers for one growing season. The seedling height, root-collar diameter, new shots length and diameter etc. were tested to analyze the morphological response of L. barbarum to climate change. The result showed that soil drought stress reduced the height, root-collar, and new shot diameter growth of L. barbarum seedling, and elevated temperature increased the root-collar growth of L. barbarum seedling. The effect of elevated temperature on seedling height and new shot growth depended on the soil moisture condition.
