Abstract:

Abstract The proline contents of anthers, pollen, pistils, and leaves were examined in several tomato (Lycopersicon esculentum Mill.) cultivars under different temperature conditions. The proline content in anthers increased with advancing development of floral buds to a maximum at anthesis. The pistil contained less proline than the anthers and did not accumulate proline with advancement of floral bud development in most cultivars. High temperature reduced proline content in anthers regardless of the stages of floral bud development. It also tended to reduce proline content in pistils of late

Abstract:

Seasonal and diurnal fluctuations were measured in the leaf proline content of three dicot species ( Lim onium gmelini, Lepidium crassifolium and Camphorosma annua), natives to an inland saline area of Hungary. Proline contents were negatively correlated to the mean monthly temperature in all three species. All the investigated species accumulated proline in February and/or March, while increases in temperature were followed by a drop in proline level by the beginning of April/May. Sodium accumulation in the leaves as well as soil water content influenced the amount of proline to a smaller ext

Abstract:

Wheat, the world’s third important cereal, is cultivated in Pakistan both in irrigated and rainfed areas. One of the major constraints of wheat production in rainfed area is drought that needs to be addressed. Although many genotypes were released that were tolerant to drought stress by improving various physiological traits but there is a need to lessen the effects of drought to boost wheat productivity. The present study was designed to identify genotype(s) suitable under drought stress by analyzing various physiological traits such as relative water content, cell membrane stability, proline

Abstract: The objective of this work was to evaluate the proline content of sunflower (Helianthus annuus) cultivars, in the conditions of natural water deficit in the Brazilian semiarid region. Thirteen cultivars were sown in experiments set in three sites in the Brazilian Northeast. Proline content was determined on leaves from plants at the R4-R5 stage. Significant differences among cultivars occurred only where water availability was lower. Proline averages ranged from 3.47 to 17.41 μg g-1. The sunflower cultivars BRS387, BRS323, and BRS324 showed the greatest proline contents with 54.74, 4

Twenty-six maize landraces were tested in order to evaluate maize seedling performance as an index for drought tolerance in adult plants. Samples were subjected to polyethylene glycol-induced osmotic stress at the early seedling stage.

Mulberries are vital for the silk industry as the sole natural food for silkworms, but their quality and quantity can be greatly impacted by environmental factors, notably water shortages or droughts. In this study, the proline content and expression levels of the Pyrroline-5-carboxylate reductase (P5CR) gene in four recommended Thai mulberry varieties (Sakhonnakorn, Sakhonnakorn 85, Burirum 60, and Srisaket 84) and one standard drought tolerant variety (SRCM9809-34) were measured under drought stress. Additionally, physiological data and antioxidative enzymatic activities were also examined.

Abstract:

Proline is considered to be associated with stress tolerance in plants. In the present study, free proline was estimated in the root, stem and leaves of 12 species of family acanthaceae collected in different seasons during 2011 from southern Rajasthan. It is observed that the proline content was higher in summer seasons in comparison to other seasons. The maximum content of proline was reported in the stem of Elytraria acaulis and minimum in roots of Justicia quinqueangularis.

Accumulation of total amino acids and proline was observed both in roots and leaves in stress treatments, with amino acid accumulation greater in leaves than in roots. In contrast, proline accumulation was greater in r
