SummaryThe common bean (Phaseolus vulgaris L.) has been the subject of a number of studies and has been described by many authors as a legume with low nitrogen fixing potential compared to other legume species. The first objective of this study is to assess the development and growth of P. vulgaris L. var. Djedida and its yield at different developmental stages (vegetative, flowering and fruiting), in the presence and absence of nitrogen fertilizer (Urea 46) in an arid climate and in a soil containing high level of CaCO3 and assimilable phosphorus. The second objective is to carry out a survey on nodulation, number of spores and mycorrhizal infection under these conditions. The results showed that the nitrogen fertilizer amendment is mainly significant (p< 0.0001) for various morphological parameters. Indeed, great improvement was observed on the majority of the morphological parameters with considerable percentages. However, no significant effect was reported for the roots length. In addition, a negligible number of nodules were obtained in the plot without fertilization and no significant effect on the number of spores was recorded. Furthermore, the effect of fertilization on the arbuscular intensity (a%, A%) and on mycorrhizal colonization (M%, m%) of the roots was found to be significant. The soil in the arid region of Biskra showed significant mycorrhizogenic potential, although the conditions in this region were not very favorable for their development, which could constitute an effective biological resource to improve the tolerance of host plants to biotic and abiotic constraints.

Uniform description of developmental stages in crops improve communication among producers, researchers and others. A standardized, accurate, and easy system is needed to describe bean (Phaseolus vulgaris L.) plant development. The objective of this study was to develop and describe stages of bean plant development in a manner which is simple but accurate. The biological cycle of the bean plant is divided into two successive phases: the vegetative stage (V) and the reproductive stage (R). Vegetative stages are determined by counting the number of trifoliolate leaves (V1 to VN) on the main stem beginning above the unifoliate leaf. Reproductive stages R1 and R2 are based on flowering, R3 and R4 on pod development, R5 and R6 on seed development, and R7, R8 and R9 on maturation.

There is a long tradition of common bean cultivation in Slovenia, which has resulted in the development of numerous landraces in addition to newly established cultivars. The genetic diversity of 100 accessions from the Genebank of the Agricultural Institute of Slovenia (AIS) were evaluated with amplified fragment length polymorphism (AFLP) markers and phaseolin seed protein. Twenty-seven standard accessions of known Mesoamerican and Andean origin, 10 wild Phaseolus vulgaris accessions and two related species, P. coccineus L. and P. lunatus L., were also included. Ten AFLP primer combinations produced 303 polymorphic bands, indicating a relatively high level of genetic diversity. Based on the marker data, unweighted pair group method with arithmethic mean (UPGMA) analysis and principal coordinate analysis (PCoA) all P. vulgaris accessions were separated into three well-defined groups. Two groups consisted of accessions of Mesoamerican and Andean origin, while the third was comprised of only four wild P. vulgaris accessions. A set of Slovene accessions formed a well-defined sub-group within the Andean cluster, showing their unique genetic structure. These data were supported by phaseolin analysis, which also revealed additional variants of “C” and “T” phaseolin types. The results are in agreement with previous findings concerning diversification of common bean germplasm introduced in Europe.

The growth regulator 2, 3, 5 triiodobenzoic add (TIBA) was applied foliarly at the beginning of flowering (R1 stage) to a vining dry bean (Phaseolus vulgaris L.) genotype, grown symbiotically in a low nitrogen containing soil. Profiles of root nodule nitrogenase and leaf nitrate reductase activities, as well as of leaf chlorophyll content throughout the postflowering period, indicate that TIBA reduced the duration of nitrogen incorporation and caused early senescence. An increase in the number of pods per plant as well as in dry matter harvest index, supports the theory that TIBA causes bean plants to shift from vegetative to reproductive growth. No seed yield increase occurred as a result of TIBA application. Symbiotic nitrogen fixation alone may not provide sufficient nitrogen to allow optimal development of an increased number of pods. Further trials under higher soil nitrogen levels are suggested.

The response of 20 open-pollinated tamarack (Larixlaricina (Du Roi) K. Koch) families from five populations to three nitrogen fertilizer levels was investigated in a greenhouse for 20 weeks. Measurements included height, root collar diameter, and dry weights. Variation among populations and the population × nitrogen interaction were not significant. Nitrogen and family effects and family × nitrogen interaction were significant for all characters studied. Stability analyses using the methods of Eberhart and Russell, Hühn, and Wricke gave similar results. The families could be divided into groups performing well at either high or low nitrogen levels or at all levels. Due to its evolution in unstable environments, tamarack appears to maintain a genetic system of adaptation based on a high level of flexibility.

In 1977, a cross section of the Phaseolus vulgaris L. world collection was screened for ozone insensitivity in fumigation chambers. A number of cultivars were selected for their high level of insensitivity to ozone (O3). These selections, along with three cultivars reported as highly insensitive and a number of white bean cultivars, were further evaluated under more stringent conditions in a controlled environment as well as under field conditions over a 2-yr period. All the white bean cultivars were sensitive to O3 under controlled conditions, but under field conditions later maturing cultivars escaped serious injury from ambient O3 levels. Early-maturing white bean cultivars tended to suffer reduced yields and earlier senescence compared with plots chemically protected from ambient O3 injury. The yields of cultivars selected as O3 insensitive in chamber fumigations were not affected by ambient field O3 levels in the field trials.

This research was conducted to investigate the effects of phytostimulators application (Messenger, Crop-Set, ISR-2000) on yield and morphological parameters of common bean cultivars grown under four irrigation regimes [25% (I25), 50% (I50), 75% (I75) and 100% (I100)]. Phytostimulators reversed the negative effect of drought on plant growth. Significant interaction was determined for all parameters except stem diameter and stomatal conductivity between phytostimulator and drought applications. The best effect on stomatal conductivity was provided from ISR-2000 (23.5% reduction) application. The highest yield was obtained from the 25% water deficiency applied with 1.91 ton per hectare. It was determined that the best results were obtained from Messenger in Efsane and Asya cultivars and ISR-2000 in the Öz Ayşe cultivar on yield. Therefore, it was concluded that the use of phytostimulators under drought stress is important for the effective use of water.
