Early tests on tolerant kabuli chickpea (Cicer arietinum L.) genotypes selection for drought stress
In order to determine early selection parameters for drought stress tolerance, an experiment was carried out, in situ, in pots under controlled climatic conditions. Drought stress tolerance of eight “kabuli” chickpea type accessions (Béja1, Amdoun 1, Nayer, Kasseb, Bochra, FLIP96-114C, FLIP88-42C and ILC3279) was evaluated with four amounts of irrigation: 100, 75, 50 and...

In vitro propagation of Ceropegia juncea Roxb
The present study was conducted to establish a protocol for in vitro propagation of an endemic medicinal plant Ceropegia juncea (Asclepiadaceae) from one month old aseptic seedling nodal explants. The highest shoot multiplication rate of 20.65 ± 0.20 shoots/explant was achieved on Murashige and Skoog medium supplemented with BAP 8.87 mM + TDZ 4.54 mM. Excised shoots were rooted...

Evaluation of cumin (Cuminum Cyminum L.) landraces under drought stress based on some agronomic traits
The present study was conducted to establish a protocol for in vitro propagation of an endemic medicinal plant Ceropegia juncea (Asclepiadaceae) from one month old aseptic seedling nodal explants. The highest shoot multiplication rate of 20.65 ± 0.20 shoots/explant was achieved on Murashige and Skoog medium supplemented with BAP 8.87 mM + TDZ 4.54 mM. Excised shoots were rooted...

Green house assessment of drought tolerance in maize (Zea mays L.) using some plant parameters
A green house study was conducted between July and August, 2009 to test and determine the drought tolerance levels of ten maize (Zea mays L.) genotypes. The top soil used was retrieved from Bediease series (Chromic lixisol). Ten genotypes, (six inbred lines and four varieties) having different...

Change of some defense compounds of cucumber treated with Bacillus cereus and salicylic acid against Meloidogyne javanica
In this research, the effects of antagonist bacterium (Bacillus cereus) and salicylic acid (SA) as chemical inducer alone and in combination against root knot nematode (Meloidogyne javanica) as the most important nematode in Iran, on cucumber roots (cv. superdominus) was investigated. The used concentrations were 109 cfu/ml for bacteria and 5 mM for SA. In greenhouse experiments some parameters were...

Mitotic chromosome studies of some accessions of African yam bean Sphenostylis stenocarpa (Hochst. Ex. A. Rich.) Harm.
In this study the chromosome number, chromosome length and mitotic indices of 21 accessions of African Yam Bean (AYB) were determined. To accomplish this, the best time to harvest growing root tips was identified by measuring mitotic index of chromosomes prepared from root tips of accession TSs148 collected at two hours interval within a 24 h study period from 8 am to 6 am of following day. Cell division occurred...

Assessment of disturbances caused by interaction of multinutrient deficiencies of sulphur, zinc and boron in mustard
In higher plants, due to indiscriminate use of fertilizers, sometimes multiple deficiencies or toxicity is created in the growing medium, which disturbed the yield and metabolism of plants. To observe the effect of sulphur (S) deficiency on zinc (Zn) and boron (B) nutrition of mustard (Brassica compestris L.) var. T9, plants were grown in refined sand in complete nutrition (control - 2 mM S, 1 µM...
