Background: Seaweed-derived extracts have gained popularity in agriculture as bioproducts with phytostimulatory effects on plant growth and development. Methods: This study assessed the effect of polysaccharide-enriched extracts (PEEs) derived from six Moroccan seaweeds on tomato growth, yield, and fruit quality. PPEs were applied to tomato plants as soil drench in a greenhouse experiment. Growth parameters including plant height (cm) and number of leaves, flowers, and flower buds were recorded every 15 days. Yield and quality parameters of the harvested fruits were also recorded after each harvest. Results: The obtained results showed that all PEEs improved the growth, yield, and fruit quality of treated tomato plants. According to principal component analysis, the presence of SO4, galactose, glucose, and maltose in the characterized polysaccharides was closely associated with their effect on plant growth, yield, and fruit quality parameters. Conclusions: PEEs obtained from Gelidium crinale,Schizymenia dubyi, Fucus spiralis, and Bifurcaria bifurcata exhibited the highest biostimulant effects and could be used as bioproducts for improved tomato yield and fruit nutritional quality.

A field experiment was carried out during 2017–2018 in the Horticulture Research Station farm in El Kanater El Khayreia, El Kalubeia Governorate, Egypt, to find out the response of foliar application of melatonin, GA3 and NAA on vegetative and fruit attributes of ‘Canino’ apricot. Different plant growth regulators influ- enced all variable parameters related to vegetative growth and fruit. Results revealed that between all growth regulators, the foliar application of melatonin following by GA3 there was the highest vegetative growth as compared to other treatments, while GA3 gave the highest yield following by melatonin as compared to other treatments. Treatment with NAA improved vegetative growth, yield and fruit quality to a lesser extent as compared to the control.

Blackberry (Rubus subgenus Rubus Watson) production has the potential to expand into the northern Great Plains with the development of the rotating cross-arm (RCA) trellis system that prevents winter injury by laying the plants horizontal to the ground so that they can be covered during cold periods. However, this will only occur with the evaluation of new cultivars and overwintering protection methods associated with the RCA trellis system. Ten cultivars under four rowcover treatments were evaluated for winter damage, vegetative growth, yield, and fruit quality. Thermo-couples monitored air temperature under each rowcover treatment. Results indicated that rowcovers differed in their ability to moderate winter air temperatures. However, temperature moderation differences from rowcovers did not correspond to plant growth differences. Instead, cultivar influenced plant growth differences. Plants under the thermal blanket with corn stover had greater yield and more berries, while fruit quality was unaffected by rowcover treatment. Differences were also found between cultivars for fruit quantity and quality. Although rowcovers enabled overwintering primocanes to produce fruit after winter temperatures reached −30 C, further research is recommended to improve winter protection techniques and the identification of higher-yielding floricane blackberry cultivars for production in the northern Great Plains.
