“…The effect of N. commune extract on germination percentage and germination speed of G. dahurica seed depended on the concentration of the extract, with a promotion at low concentrations (1-10 · 10 )6 ) and an inhibition at a high concentration (100 · 10 )6 ) (Figures 1,2). The results coincide with those in earlier studies dealing with Vigna sinensis (cowpea; Sivasankari et al 2006) and Orobanche ramose (Economou et al 2007). The promotion at low concentrations has been reported to be due to the presence of some growth promoting regulators, especially such as extracellular polysaccharides (Brüll et al 2000;Sheng et al 2001b).…”

This work aimed to evaluate the effect of water extract of Nostoc commune Vauch. on seed germination of Gentiana dahurica Fischer. Extract solution of N. commune was obtained by soaking 10 mg dry matter N. commune material in 1 L of distilled water (pH 10.0) at 80°C, and concentrating the filtrate 10‐fold by evaporation. Seed germination was tested at 25/15°C under a photoperiod of 8‐h light/16‐h darkness. The extract increased the total germination of G. dahurica by 37.0, 47.7, 34.7 and 11.7% as compared to 39.2% in the control (no extract) at concentrations of 1, 2, 5 and 10 × 10−6, respectively, and the speed of germination by 3.58, 4.89, 2.93 and 0.20%, respectively, compared to 2.76% in the control. The results indicate that water extract of N. commune improves germination of wild G. dahurica at low concentrations. This information may be useful for artificial cultivation of G. dahurica.

“…Other compounds of natural origin, such as fungal phytotoxins, natural amino acids (Vurro et al. , 2009) or plant or algae extracts (Economou et al. , 2007) were also suggested for use in broomrape management strategies, being able to inhibit seed germination or seedling elongation, or, conversely, stimulate suicidal seed germination in the absence of the host (Vurro et al.…”

Revisiting strategies for reducing the seedbank of Orobanche and Phelipanche spp.

et al. 2009

Summary Weedy Orobanche and Phelipanche species are important in Southern and Eastern Europe, the Middle East and North Africa, and have recently been reported in the USA, Australia and some countries in South America. Rather than being controlled, the Orobanche and Phelipanche problem is increasing, both in intensity and in acreage. Large areas of new territory are at risk of invasion, if care is not immediately taken to limit the introduction of parasitic seeds and to educate farmers and others to be alert for new infestations. There is an urgent need to re‐evaluate novel integrated Orobanche and Phelipanche management programmes that will allow a better control of the parasite species and limit their distribution. The main obstacle in the long‐term management of Orobanche and Phelipanche infested fields is the durable seedbank, which may remain viable for decades in the field. Large quantities of long‐lived seeds give the parasite genetic adaptability to changes in host resistance and cultural practices. As long as the seedbank is not controlled, the need to control the parasite will persist whenever a susceptible host is grown in the infested field. We discuss strategies for seedbank reduction, paying particular attention to cultural practices, whereas chemical and biological control methods are covered by other reviews in this issue.

“…Some chemical analysis revealed that seaweed extracts have all major and minor nutrients, and all trace elements; aliginic, amino acid, vitamins, auxins (Zodape, 2001;Zhang et al, 2003;Zhang and Ervin, 2004;2008). Seaweeds and their extracts have been used in many countries as soil conditioners, crop growth, and increase the yield, yield components (Verkleij, 1992;Norrie and Keathley, 2006;Chouliaras et al, 2009;Sabir et al, 2014) enhance seed germination, seedling vigor (Kambayashi and Watanabe, 2005;Demir et al, 2006;Economou et al, 2007), increase uptake of nutrients, ripening of fruits, increases shelf-life of the produce, and resistance to fungal diseases such as leaf stripe disease symptoms in grape (Calzarano et al, 2014) and Alternaria radicine and Botrytis cinerea in carrot (Jayaraj et al, 2008) and shoot length, root length, fresh and dry weights of seedlings were significantly increased in wheat (El-Din, 2015). Many different beneficial effects have been also reported for crops treated with seaweed extract.…”

A field experiment was carried out in Aydın region, Turkey during the two successive cotton growing seasons 2010 and 2011. The compounds have did not affect the population amount of Empoasca spp., Bemisia tabaci Genn., Frankliniella spp., whereas they affected Aphis gossypii Glov. and Liriomyza trifolii Burgess infestation. The highest population of Aphis gossypii was observed in Active Black Up treatment. On the other hand, the highest damage caused by L. trifolii was in Promina treatment. Among the predators, population in Thysanoptera order was significantly different in the treatments. More thrips populations were observed in Promina. The application of compounds significantly affected on the yield. The highest yield was obtained from Aminoquick treatmetn that has 95% organic matter and produced 28% more yield compared to the control. Treatments had no significant effects on plant height, lint percentage, boll weight, fiber properties, except for number of boll per plant and micronaire. The results showed that these compounds increased the yield, did not enhance the pests' population and not harmful to predators except for Thysanoptera. Thus, containing seaweeds and more organic foliar fertilizer compounds should be considered in integrated management of organic or conservative cotton fields.
