Seed Endophytes

Pre-sowing seed treatment with systemic fungicides is a firmly entrenched practice for most agricultural crops worldwide. The treatment is intended to protect the crop against seed- and soil-borne diseases. In recent years, there is increasing evidence that fungicidal applications to manage diseases might inadvertently also affect non-target organisms, such as endophytes. Endophytes are ubiquitously present in plants and contribute to plant growth and development besides offering resistance to biotic and abiotic stresses. In seeds, endophytes may play a role in seed development, seed germination, seedling establishment and crop performance. In this paper, we review the recent literature on non-target effects of fungicidal applications on endophytic fungal community and discuss the possible consequences of indiscriminate seed treatment with systemic fungicide on seed endophytes. It is now well recognized that endophytes are ubiquitously present in all parts of the plant, including the seeds. They may be transmitted vertically from seed to seed as in many grasses and/or acquired horizontally from the soil and the environment. Though the origins and evolution of these organisms in plants are a matter of conjecture, numerous studies have shown that they symbiotically aid in plant growth and development, in nutrient acquisition as well in protecting the plants from abiotic and biotic stresses. Against this background, it is reasonable to assume that the use of systemic fungicides in seed treatment may not only affect the seed endophytes but also their attendant benefits to seedling growth and establishment. While there is evidence to indicate that fungicidal applications to manage plant diseases also affect foliar endophytes, there are only few studies that have documented the effect of seed treatment on seed-borne endophytes. Some of the convincing examples of the latter come from studies on the effect of fungicide application on rye grass seed endophyte AR37. More recently, experiments have shown that removal of seed endophytes by treatment with systemic fungicides leads to significant loss of seedling vigour and that such losses could be partially restored by enriching the seedlings with the lost endophytes. Put together, these studies reinforce the importance of seed endophytes to seedling growth and establishment and draw attention on how to trade the balance between the benefits of seed treatments and the direct and indirect costs incurred due to loss of endophytes. Among several approaches, use of reduced-risk fungicides and identifying fungicide-resistant endophytes are suggested to sustain the endophyte contribution to early seedling growth.

The objective of this work was to evaluate the performance of soybean seedlings in different seed treatments. The experiment was conducted in the municipality of Mineiros, GO. The soil was classified as Quartzarenic Entisol. The experimental design was randomized blocks in factorial 5x4, corresponding to seed treatments (Water, Cruiser, Fipronil Alta, Fortenza and Standak Top) in four soybean cultivars (Bonus, Ultra, Extra and BKS7830), in four replications. Before planting, pre-planting desiccation was performed. The fertilization used was 450 kg ha-1 of fertilizer 05-25-15 applied in the furrow and in a single dose next to the sowing. During the conduction of the experiment the control of pests, diseases and weeds were carried out as necessary, respecting the best practices and integrated management. The data obtained were subjected to the assumptions of the statistical model, verifying the normality and homogeneity of the residual variances, as well as the additivity of the model. Uni and multivariate tools were applied. The analysis were performed at the interface Rbio and R. The interaction of soybean cultivars and types of seed treatment showed variations in all analysis evaluated in soybean seedlings. The best performances were verified among the cultivars BKS7830 that expressed the largest shoot fresh matter when submitted to Cruiser seed treatment, while the highest root length was expressed in the cultivar Ultra in the Fortenza seed treatment.

Wild Safflower

Seeds of wild safflower (Carthamus oxyacanthaBieb.) collected from the Bajgah area, Iran, in 2 successive years were subjected to stratification and scarification treatments and their germination percentage and subsequent seedling growth (length) were measured at room temperature (23 ± 2 C). Maximum germination and seedling length occurred in the seeds stratified in moist sand at 4 C for 2 weeks. The response of the freshly-harvested seed to scarification was linear while that for 1-yr-old seed was quadratic. Both scarification and stratification independently increased germination but germination never reached the viability level of the seed.

Background: Sarpagandha is an indigenous medicinal herb of Indian continent. It has many medicinal properties. Due to increasing demand of Sarpagandha, its exploitation is increasing continuously but for lack of cultivation, this plant has been listed in endangered category. Commercially, it is propagated through seeds but the main barrier of seed propagation is its irregular and low germination. Hence, the current study was undertaken to study the effect of growing media and seed treatment methods on seed germination and seedling growth of Sarpagandha to eliminate the inhibitory effect of the hard stony endocarp.Methods: Seed germination and seedling growth experiments of Sarpagandha were carried out with following different seed treatments, T1 (Control), T2 (Water soaking for 24 hours), T3 (water soaking for 48 hours), T4 (Water soaking for 24 hours + cotton cloth wrapping for 24 hours), T5 (GA3 200 ppm), T6 (FYM treatment for 24 hours), T7 (FYM treatment for 48 hours), T8 (Hot water treatment) and T9 (Cow dung treatment for 24 hours). Experiment was laid out in CRD. The data recorded on the various parameters were analyzed at 5% level of significance by using ANOVA.Result: Results indicated highest germination percentage (51), lowest mortality percent (49), minimum days for initiation of germination (23), minimum days taken for germination completion (33), highest speed of germination (3.77), maximum vigour index (1441.44), highest root (11.27 cm) and highest shoot length (17 cm) in T5 (GA3 200 ppm) followed by T3 (water soaking for 48 hours). Indicating, T5 (GA3 200 ppm) to be best seed treatment for higher germination and subsequent seedling growth of Sarpagandha (Rauvolfia serpentine L.).
