One-bud leafy cuttings have limited storage capacity, due to the small size of the stem, and are exposed to prolonged stress conditions. Controls included untreated cuttings.

No se encontraron diferencias significativas con respecto a la firmeza del fruto, concentración de sólidos solubles totales, peso del fruto, rendimiento total, peso del fruto comercializable, rendimiento comercializable, y rendimiento por planta. Marine algal seaweed species are often regarded as an underutilized bioresource, many have been used as a source of food, industrial raw materials, and in therapeutic and botanical applications for centuries. (Proceedings of the Xth International Symposium on, Plant Bioregulators in Fruit Production, 2005). The objectives of this study were to determine if exogenous hormone or hormone-like substances could alleviate UV-B damage to 'Georgetown' kentucky bluegrass (Poa pratensis L.) under greenhouse conditions. Histochemical staining showed Stimplex®-induced GUS activity in leaf as well as in the root tissues. J, Vollner L (1990) Agrochemical formulations for improved efficacy, and reduced environmental impacts: slow release formulations, with natural polymers. Also, plants grown on sustrata containing at least ten percent compost had significant benefits compared to control plants, improving growth and water stress resistance. Leaf area index, SPAD values (chlorophyll content) were also significantly more than Large quantities of green seaweed, linked probably to eutrophication, are cast ashore every summer on the Puerto Madryn beaches (Patagonia, Argentina, 42 degrees 5, 65 degrees W). Bot Mar, Kim MS, Park GD, Jun SW, Lee S, Park JS, Hwang SJ (2005), Controlled release tamsulosin hydrochloride from alginate beads, with waxy materials. showed growth enhancement effects over control plants; a more advanced developmental stage when compared with, untreated plants and the effect was concentration depen-. These, furanones in nature seem to interfere with QS in marine, erally avoid plants treated with seaweed extracts (Ste-, seaweed extracts sprayed onto apple trees reduced red, of seaweed extract application resulted in a level of control, similar to that of acaricides (Stephenson, more, it was observed that the use of Maxicrop on straw-, extracts might contain chelated metals that have been, shown to reduce the population of red spider mites (Ter-, Seaweeds and seaweed products are increasingly used in, crop production. For, to confirm the action of seaweed extracts (, Drought-stressed plants treated with a combination of, humic acid and seaweed extract had root mass enhanced by, 21–68%, foliar tocopherol by 110%, and endogenous, zeatin riboside (ZR) by 38%.

The advent of plant transformation has placed within our grasp the possibility of engineering greater stress tolerance in plants by enhancements of the antioxidative defence system.

Effects on the Plant Proc Int Seaweed Symp 5:405–415, Stevens GA, Westwood MN (1984) Fruit set and cytokinin-like, activity in the xylem sap of sweet cherry (, affected by rootstock. The monomers may alternate in, some regions of the alginate (heteropolymeric), or they, may occur in contiguous groups to produce homopolymeric, sections with either monomer within the alginate molecule, polysaccharides, laminaran and fucoidan exhibit a wide, range of biological activities (Rioux and others, Direct effects of fucoidan on plants have not yet been, reported but sulfated fucoidans from brown algae have, evinced biological activities in mammalian systems, stimulate natural defense responses in plants and is, involved in the induction of genes encoding various path-, ogenesis–related (PR) proteins with antimicrobial proper-, The concentration of mineral nutrient elements present in, commercial seaweed concentrates (SWCs) alone, account for the growth responses elicited by seaweed, in various plant growth bioassays have led to speculation, that SWCs contain plant growth-regulatory substances, growth responses induced by seaweed extracts implies, presence of more than one group of plant growth-promot-, Cytokinins have been detected in fresh seaweeds (Hus-, dro derivatives of these two forms (Stirk and van Staden, (LC/MS) analysis of 31 seaweed species representing, various groups revealed that zeatin (Z) and isopentenyl (IP), conjugates of cytokinins are the predominant cytokinins, tained aromatic cytokinins BAP (benzyl amino purine) and, topolin (6-[3-hydroxybenzyl-amino] purine) derivatives), Marine algae are also reportedly rich in auxins and, auxin-like compounds (Crouch and van Staden, acetic acid) per gram of dry extract (Kingman and Moore, a remarkable root-promoting activity on mung bean, an, effect reminiscent of auxins (Crouch and van Stade, Gas chromatography/mass spectroscopy (GC/MS) analysis.
