Potato (Solanum tuberosum L.) is one of the most important food crops worldwide. Current potato varieties are highly susceptible to drought stress. In view of global climate change, selection of cultivars with improved drought tolerance and high yield potential is of paramount importance. Drought tolerance breeding of potato is currently based on direct selection according to yield and phenotyp...

Plant phosphoinositide-specific phospholipases C (PI-PLCs) function in several essential plant processes associated with either development or environmental stress. In this report, we examined the expression patterns of TaPLC1 under drought and high salinity stress at the transcriptional and post-transcriptional levels. TaPLC1 mRNA was expressed in all wheat organs examined. U73122 and edelfosi...

Drought is one of the most important natural phenomenon which affects on plant growth. Alfalfa (Medicago sativa L.) is an essential fodder product which has extensive and depth roots system, this advantage enables the plant to tolerate long term drought without any damage to its regrowth process. In order to measure germination percentage and rate, root and shoot growth of 6 alfalfa cultivars (...

Environmental stresses specially drought, play an important role in decreasing plant growth, particularly during germination in dry and semi dry area. To considering the effect of drought stress caused by polyethylene glycol on germination and characteristics of 2 spices of Sesamum indicum, we had done factorial and complete accidental plot with 4 treatments and 3 times repetition. Experimental...

Supercritical fluid extraction was used to extract the alkaloid N-[7-(3',4'-methylenedioxyphenyl)-2(Z),4(Z)-heptadienoyl]pyrrolidine from leaves of Piper amalago L. A three-level orthogonal array design matrix, OAD OA9(34), was used for optimization of the parameters of supercritical extraction of the alkaloid, employing supercritical carbon dioxide: extraction time (20, 40, and 60 min), temper...

poor establishment of seedling due to both drought and lack of water is one of the most important problems in arid and semiarid regions such as iran. so, in order to evaluate the effect of lentil seed size on germination and seedling growth properties affected by drought stress, a completely randomized design with factorial arrangement and 3 replications conducted using two lentils genotypes (r...

Abstract Albardine ( Lygeum spartum L.) is one of the major native grass species semi-arid and arid regions Mediterranean basin. In Algeria, it much more widespread on high plateaus southern Oranais. This occupies an important place in steppe region because has many ecological, economic, fodder interests. The present work aims to study tolerance L. seeds water salt stress, two abiotic factors t...
