This study investigates the effect of silicon (Si) application on saffron plantgrown under salt stress. Therefore; Saffron, Crocus sativus L. was grown in different treatments of NaCl in presence and absence of 1 mM of silicon in its soluble form, orthosilicic acid(H4SiO4). Our results exhibited that the application of silicon enhanced the physiologicalstudied parameters and morphological attributes of saffron stigmas; the length of stigma improvement was 29% and 41,4% in saline treatments of 50 mM and 100mM respectively in presence of silicon compared to the same treatments without silicon, the dry weight of the stigma boosted by 40% for the treatment of 50mM of NaCl and 20% for 100 mM treatments compared to the same treatments in absence ofsilicon. Siliconaddition ameliorated RWC, total phenolic,anti-radical leaves activity and K+ contents and K+/Na+ ration in both roots and leaves. These results suggested that Si application enhanced saffron plant and improved the weight and length of saffron stigma.

Abstract One purpose of assessing the soil alive and active community is the identification of beneficial bacteria to use them as biological fertilizers, replacing or supplementing synthetic fertilizers. Such biofertilizers are predicted for the sustainability of agricultural production, especially for low input systems such as saffron fields. The aim of this work was to isolate and identify saffron rhizobacteria and to evaluate their possible effects on saffron growth. During 2013/14, some bacteria were isolated from the rhizosphere of the saffron plantations of different age in Gol village, Birjand, Iran. In total, 12 bacteria species were identified based on phenotypic traits and 16S rDNA sequences analysis. The strains were identified as B. subtilis, B. anthracis, B. cereus, B. megaterium, Bacillus sp., Paenibacillus, Pseudomonas fluorescens, P. putida, Escherichia coli, Pectobacterium sp. and Pantoea sp., with the dominant population belonging to the genus Bacillus. In the field study, inoculation of soil with these strains did not affect the leaf dry weight of the cultivated saffron, however, the strains of P. fluorescens increased the leaf area while P. fluorescens, Paenibacillus, Pectobacterium and B. megaterium increased the number of daughter corms and Azotobacter, B. cereus, B. subtilis and B. megaterium increased the corm weight. Our finding revealed that some bacteria present in the soil of perennial saffron plantations have a promising potential for developing as a plant growth promoting rhizobacteria.

Crocus Sativus L

Saffron (Crocus sativus L.) is renowned as the most expensive spice in the world. This perennial species belongs to Iridaceae family. Germplasm collection and preservation are one of the main priorities for a better and successful crop improvement. In this study, preliminary evaluation of morphological and molecular diversity among 29 accessions of saffron from Iran was investigated. Several important traits such as length and number of leaves, leaves surface, fresh and dry weight of leaves were measured. RAPD markers using 17 primers were also used to evaluate molecular divergence among the accessions. Simple correlation analysis among morphological traits showed significant positive correlations in most characters, but negative correlations between emergence time and other characters. Cluster analyses based on morphological and molecular data produced dissimilar groups in due to data type. In both dendrograms three distinct groups were resulted and the most of the accessions were placed in the first cluster. Also, the groupings showed no association between diversity patterns and geographical origins. In molecular analysis, out of 17 primers that produced 108 polymorphic bands, 12 primers showed complete polymorphism. The maximum and minimum genetic similarities were 0.98 and 0.42, respectively. This results support abilities of these approaches as economical and quick technique to determination of diversity among saffron accessions.

The chemical composition of the Australian bull kelp, Durvillea potatorum, was determined. As a percentage of the whole stipe dry weight, components were: Crude fibre, 57.40 %; alginic acid, 35.15 % ; "cellulosic" polysaccharide, 22.61 % ; laminarin, 1.79 %; mannitol, 3.20%; nitrogen, 1.21 %; ash, 28.09 %; insoluble ash, 8.81 %; Ca2+, 1.47%; Mg2+, 0.44%; Na+, 1.45%; K+, 3.36%; PO42-, 5.15%; Cl-, 5.87%; SO4-, 3.49 %; I-, 0.25%; and chlorophyll, 0.01 %. Tissue fractionation showed that the peripheral layer contained approximately two-thirds of the total chlorophyll and three-quarters of the total phenolic compounds, but only one-tenth of the total alginic acid. In whole stipes up to two-thirds of the alginic acid was in a soluble form.

Abstract A laboratory experiment regarding germination and seedling growth test was conducted with three black gram genotypes tested under three salinity levels (0, 75 and 150 mM), for 10 days, in sand culture within small plastic pot, to investigate the germination and seedling growth characteristics. Different germination traits of all black gram genotypes, like germination percentage (GP), germination rate (GR), coefficient of velocity of germination (CVG) greatly reduced, as well as mean germination time (MGT) increased with increasing salt stress. At high salt stress, BARI Mash-3 provided the highest GP reduction (28.58%), while the lowest was recorded (15.79% to control) in BARI Mash-1. Salinity have the negative impact on shoot and root lengths, fresh and dry weights. The highest (50.32% to control) and lowest reduction (36.39%) of shoot length were recorded in BARI Mash-2 and BARI Mash-1, respectively, under 150 mM NaCl saline conditions. There were significant reduction of root lengths, root fresh and dry weight, shoot length, shoot fresh and dry weight in all genotypes under saline condition. The genotypes were arranged as BARI Mash-1 > BARI Mash-3 > BARI Mash-2, with respect to salinity tolerance.
