Micropropagation of three genotypes of Indian mustard [Brassica juncea (L.) Czern.] using 7-days old seedling-derived transverse thin cell layer (tTCL) explants was accomplished. The genotype, explant source and addition of silver nitrate to the medium significantly influenced shoot bud induction. MS medium with 26.6 μM of 6-Benzylaminopurin (BAP) and 3.22 μM of 1-naphtaleneacetic acid (NAA) wa...

The effects of waterlogging the soil on leaf water potential, leaf epidermal conductance, transpiration, root conductance to water flow, and petiole epinasty have been examined in the tomato (Lycopersicon esculentum Mill.). Stomatal conductance and transpiration are reduced by 30% to 40% after approximately 24 hours of soil flooding. This is not due to a transient water deficit, as leaf water p...

The Diagnosis and Recommendation Integrated System (DRIS) is an alternative tool for the evaluation of nutritional status and fertilizer recommendation of several crops. However, as this methodology implies the establishment of norms or standards, without which one cannot infer about the nutritional status of a crop, in Portugal this tool has little application. The aim of this study was to est...

The use of rootstocks particularly for sweet cherry cultivars is of great importance for successful and sustainable production. Choosing the right cherry rootstocks is just as important as choosing the right cultivar. In this study, 110 sweet cherry, 30 sour cherry, and 41 mahaleb types displaying rootstock potential for sweet cherry cultivars were selected from Central and East Black Sea Regio...

Tetramorium amalae sp. n. is described and illustrated from Saudi Arabia based on two worker caste specimens collected in Al Bahah region. The new species belongs to the T. shilohense group and appears to be closely related to T. dysderke Bolton from Nigeria. T. amalae is distinguished by having well-developed frontal carinae, smaller eyes, greater head length and width, greater pronotal width,...

Biodiversitas 23: 928-937. is an ornamental plant with intense cultivation hybridization practices because the uniqueness beauty its leaves. a very large number species interesting to study, especially Indonesia one resource centers this genu...

In this study, 4 Salvia species found in the section distributed Artuklu district
 of Mardin province were analyzed comparatively terms anatomy. Plant specimens Salvia
 collected from 11 localities. Anatomical studies performed on preserved
 70% alcohol. Transverse sections taken roots, stems, leaves, and petioles species
 examined under a light microscope for anatomical exa...

The management of the moringa to produce biomass, as it is for other vegetal species, must consider some aspects that foster productivity. Among these aspects, cultivation density a crucial element. This research aimed assess effects spacing and cuts on growth moringa. treatments consisted four spacings: 0.5 x 1.0 m; 0.83 1.25 1.66 m. experimental design was randomized-block with five repetitio...

The sedimentaion of amyloplasts in tomato leaf petiole cells, when influenced by gravistimulation, gravistimulation and phytohormone epine, an exogenous source ethylene ethephon for a period 0.25–24 h, was demonstrated. Ethephone significantly slowed down the sedimentation serving as statolytes which correlates with its inhibitory effect on formation gravitropic bending stem.

Two new species of the genus Timia Wiedemann, 1824 are described and illustrated. Timia lazebnayae sp. n. from Uzbekistan has yellow body and is similar to Timia gobica Zaitzev, 1982, differing from it only by the entirely yellow flagellomere 1. Timia shatalkini sp. n. from Mongolia has dark body and differs from all other dark-colored representatives of the genus by the cell r4+5 being complet...
