Abstract To investigate the effects of water withholding on 17 tomato ( Solanum lycopersicum L.) landraces collected from different climatic zones Iran and two commercial hybrids, polyphasic OJIP fluorescence transient, relative content (RWC), electrolyte leakage (EL) vegetative growth parameters were analyzed. Duncan’s multiple range test (DMRT) for all studied drought factor index (DFI) based performance absorption basis (PI abs ) used screening plants their tolerance to condition. Result...

Abstract Changes in carbohydrates, enzymes, and pigments were investigated the R ed G arlic ( A llium sativum L.) cv. Azarshahr bulbs storage from harvest to sprouting. For period, garlic cloves of same diameter with 3–4 g weight arranged dark condition exposed 4 21°C, separately. Soluble sugar, total glucose, sucrose, fructose, starch, chlorophyll a , b ab carotenoid, anthocyanin, lipase, α ‐amylase, protease measured every 2 weeks up sprouting time. Result revealed that levels declined at...

The evaluation of A. cepa biodiversity provides onion breeders with great prospects to obtain plants high resistance environmental factors, remarkable yield, and product quality. Genetic diversity assessment a collection nine short- long-day landraces varieties originated from different Iranian regions, using ISSR markers UPGMA dendrograms, was carried out for the first time. Short-day (Sarze, Sarkoreh, Kerman) low latitude short-day hybrids (Mirela Soberana) demonstrated genetic similarity,...

Abstract The magnetic fields influence the biological systems by several mechanisms. field induces translation and rotation movements of electric charges. effects a stationary on germination initial stages growth Lettuce seeds (Lactuca sativa var.longifolia) have been studied. were exposed to strength (125 250mT) for different time including 0, 1, 6, 12 24 hour. results revealed significant difference (P<0.01) traits field. By conducting results, parameters in 0 h underneath 6 both 125 250mT...

Abstract Garden asparagus ( Asparagus officinalis L.) is a diploid (2n = 2x 20), perennial and dioecious species belonging to subgenus worldwide cultivated as vegetable crop. A narrow genetic base has been pointed out for the current cultivars. Crop wild related (CWR) could be valuable resource in this crop but they have underused up now. To investigate phylogenetic relationships between CWR from different origin A. L., 12 EST-SSR markers were used assess variability of 20 accessions. These...

Abstract In vitro culture of twin-scaling explants Galanthus transcaucasicus with different concentrations plant growth regulators (PGRs) including 0.5, 1, 2, 3, 4, 6, 8, and 10 mg L-1 naphthaleneacetic acid (NAA) 4 benzyladenine (BA) was studied. After 18 weeks, the number regenerated bulblets intensity callus measured. Subsequently, were transferred to a medium NAA BA and, after 15 length diameter The highest obtained on or 8 1 BA. detected 6 2 occurred four mgL-1 (9.4 mm), while lowest...

Asparagus is a large genus comprising three subgenera (Asparagus, Protasparagus and Myrsiphyllum) with species distributed in Africa, Asia, Australia Europe. The southwest of Asia includes the natural distribution several this genus. Also, proposed center origin garden asparagus (A. officinalis) located region. genetic diversity phylogenetic relationships among twelve diploid polyploid (4x, 8x 10x) accessions (7 A. officinalis + 3 verticillatus 1 persicus breslerianus), collected from...

Abstract This research evaluated phenotypic diversity among 16 Rosa persica accessions collected from their native habitats in Iran. Twenty-two quantitative traits were this species based on morphological markers and according to previously described standard methods. An analysis of the revealed significant differences most them ( p ≤ 0.01 ). In addition, mean comparison showed that "Neishabor 3" accession had highest plant height, "Arak" flower diameter accessions. Principal component five...
