in this regard, the morphophysiologic and anatomic characteristics of six olive cultivars (nabali, feshomi, arbequin, zard, gordal and roghani) were investigated under drought. experiments were designed based on factorial and complete block random plot with two control treatments, -1.5 mpa stress and three replicates. the investigated factors were as follows: leaf area, specific leaf area, leaf...

safflower oil seed has high adaptability to different kinds of abiotic stresses such as drought and salinity. the aim of this study was to evaluate the effects of drought stress at different phenological stages on relative water content (rwc), leaf canopy temperature, seed yield and its components in spring types of safflower. the study was carried out in east azarbaijan research center for agr...

Cunninghamia plays an important role in China’s southern forest industry the face of increasingly arid climate; thus it is urgent to identify and screen drought-tolerant varieties. In this study, 2-year-old seedlings C. unica lanceolata from four provenances were subjected water-break tests, their physiological responses different drought conditions observed. The results showed that with aggrav...

Two-year old seedlings of Silver buffaloberry (Shepherdia argentea (Pursh) Nutt.) were exposed to NaCl salinity (0, 200, 400 and 600 mmol/l) for 30 days. Leaf water potential (Ψw), chlorophyll contents (Chl a, b, and a + b) and K+ content decreased with an increase in salinity. Relative water content (RWC) declined significantly with 400 and 600 mmol/l NaCl. However, salinity induced an excessi...

Two tolerant (BB24 and BB43) and two susceptible (BARI busbean-2 and BB04) genotypes of common bean (Phaseolus vulgaris L.) were evaluated for their water status and its relationship with reproductive responses under continuous water stress (50% field capacity) and control (80% field capacity) conditions in a net house covered with polyethylene sheet at the Bangabandhu Sheikh Mujibur Rahman Agr...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

Plants with citrus variegated chlorosis (CVC), a disease caused by the xylem-limited bacteria Xylella fastidiosa, have leaves with water deficiency symptoms and are associated with decreases on the net photosynthesis and transpiration rates. Using healthy and CVC-affected ‘Pêra’ sweet orange plants on ‘Rangpur’ lime rootstock, the leaf gas exchange variables were measured with an open-gas porta...
