“…In particular, the best results concerning productivity, oil content and earliness of maturity (colour and firmness) were observed in the trees treated with N + B + SWE. Similarly, Chouliaras et al 10 experimenting with kiwifruits observed that foliar application of an SWE ( Ascophyllum nodosum L.) increased the fruit size remarkably and advanced their maturity by 10–15 days. Moreover, a commercial type of SWE ( Ascophyllum nodosum L.) presented similar trends concerning fruit size and maturity of ‘Clementine’ mandarin and ‘Navelina’ orange 11.…”

“…Seaweed extract, being organic and biodegradable, is important in sustainable agriculture 6. In various crops, the use of seaweed products may lead to increased crop yield, quality and uptake of inorganic elements from the soil, resistance of plants to stress conditions, reduced incidence of fungal and insect attack and lower productivity cost 7–11. There is not adequate information in the literature about the effects of seaweed extracts on olive tree yield, fruit growth and oil quality.…”

BACKGROUND: There is not adequate literature on effects of seaweed extracts (SWE) on yield and nutritional status of olive trees as well as olive oil quality. In this work, a study of the effects of a seaweed extract applied foliarly (0.5% v/v) in addition to soil application of N (500 g NH 4 NO 3 per tree) and B (150 g borax per tree) on productivity, fruit parameters, nutritional status and olive oil quality of a Greek olive cultivar was performed.

“…Several commercial and experimental seaweed extracts can also be employed to produce potent biostimulants. Foliar application of A. nodosum extract in kiwi plants after flowering increased the weight and maturity of the harvested fruits (Chouliaras et al, 1997 ). In clementine and orange trees, foliar spray of seaweed extracts at budding stage positively affected bud sprouting and full bloom, and enhanced gibberellin content and fruit yield (Fornes et al, 2002 ).…”

Foliar Nutrition, Biostimulants and Prime-Like Dynamics in Fruit Tree Physiology: New Insights on an Old Topic

Despite the fact that the usage of foliar nutrients has long history, many aspects of fertilization through leaves are still unknown. Herein, we review the current knowledge regarding the canopy fertilization putting special emphasis on Fe nutrition and briefly provide insights into the nanofertilizer technology of the foliar feeding of fruit crops. In addition, this paper discusses the main aspects of the foliar application of biostimulants regarding crucial factors of fruit cropping systems, such as fruit yield/size, tolerance to environmental stresses, and nutrient availability. Also, we specifically discuss the role of hydrogen peroxide (H2O2) and nitric oxide (NO) as priming molecules and their possible cross-talk with biostimulants in fruit tree physiology. Finally, a view of the key issues for future fundamental and applied research in the topic is put forward.

“…Scientific study into the use of Ascophyllum nodosum extract (ANE) and its mode of action is ongoing. Positive responses to ANE application have been reported in various agricultural crops (e.g., Blunden et al 1997;Chouliaras et al 1997Chouliaras et al , 2009Colapietra and Alexander 2006). Applying ANE increased root dry weight in creeping bentgrass (Agrostis palustris Huds.)…”

J. 2012. Root growth of containerized lodgepole pine seedlings in response to Ascophyllum nodosum extract application during nursery culture. Can. J. Plant Sci. 92: 1207Á1212. Vigorous root growth immediately after spring planting is crucial to ensure a well-developed root system before the occurrence of drought events associated with climate change. The objective of this study was to enhance spring root growth of containerized lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) seedlings. Seedling culture began in April. In September, seedlings were root drenched with an extract of the brown marine alga Ascophyllum nodosum (L.) Le Jolis in finisher fertilizer at rates of 1:750, 1:500, and 1:250. Finisher fertilizer alone served as control. Applications were made three or six times. Seedling culture continued until lifting in December, and then seedlings were freezer stored. Frequency of application had no effect on root growth, whereas rate of application had a significant effect. Compared with control, the 1:750, 1:500, and 1:250 rates significantly reduced total length of the root system in mid October. After overwintering and growing under favorable environmental conditions for 21 d, the 1:500 rate significantly increased the total number of white roots, as well as the number of both short and long white roots. These results suggest that application of Ascophyllum nodosum extract may be a valuable nursery practice to increase spring root growth, thereby enhancing drought resistance.
