“…Similar observations were reported by Neri et al (2002) in strawberry crops where foliar applications of humic acids stimulated pigment production and water use efficiency and maintained photosynthetic rates. Additionally, Afrousheh et al (2010) reported that nutritional deficiencies in Pistacia vera resulted in lower photosynthesis, transpiration, and stomatal conductance rates.…”

Cien. Inv. Agr. 43(1):25-37. Seaweed extracts are used as nutritional supplements, biostimulants, or biofertilizers in agriculture and horticulture to increase plant growth and yield. In this experiment, foliar applications of bio-stimulant derivate from seaweed extract were tested on plant growth, leaf gas exchange properties, and proline accumulation in lulo seedlings cultivated under greenhouse conditions. Lulo plants were split into four treatments: (i) plants with soil fertilizer; (ii) plants treated only with foliar bio-stimulant sprays; (iii) a combination of soil fertilizer plus a foliar bio-stimulant application; and (iv) a control treatment (without nutrient application). Lulo plants treated with soil fertilizer and foliar bio-stimulants increased growth, as this group of plants showed a higher total plant dry weight, stem diameters, and absolute growth rate. Lulo plants without soil fertilizater and treated with foliar bio-stimulant application had lower leaf gas exchange (photosynthesis, stomatal conductance, and plant transpiration) and leaf chlorophyll content. Foliar biostimulant sprays enhanced the partitioning of dry mass in floral cushions. In conclusion, the application of foliar bio-stimulant applications as a complement to soil fertilizer is a technique that can be employed in the cultivation of lulo because foliar sprays of these kinds of agrochemicals can enhance dry matter accumulation and blooming.

The possibility of communication between plants was proposed over 25 years ago, although previous demonstrations have suffered from methodological problems and have not been widely accepted. Micromelalopha troglodyta (Graeser) and Clostera anastomosis (L.) (both Lepidoptera: Notodontidae) are important leaf-feeding insects on poplars (Populus spp.; Salicaceae). There is no report of M. troglodyta-or C. anastomosis-induced plant-plant communication up to now. To understand the regulatory mechanism of poplar defense responses, the specific activities of the presumed antiherbivore enzymes phenylalanine ammonia lyase (PAL), lipoxygenase (LOX), polyphenol oxidase (PPO), and peroxidase (POD) were determined in poplar seedlings treated with herbivore infestation and volatiles, artificially damaged seedlings, and intact healthy poplar seedlings growing nearby. The expression levels of PPO, POD, PAL, and LOX were elevated in poplar seedlings treated by herbivore infestation, mechanical wounding, methyl jasmonate, methyl salicylate, or benzothiazole. Furthermore, plants neighboring the treated poplar seedlings also showed increased expression levels of PPO, POD, PAL, and LOX relative to the control. These induced responses against feeding injury, mechanical wounding, and volatile treatment in expression levels of PPO, POD, PAL, and LOX suggest interplant communication between poplar seedlings.

“…The seedlings were grown in a growth chamber at 25 ± 1°C and with a L16:D8 photoperiod. They were watered daily and supplied with Hoagland nutrient solution (Afrousheh et al 2010) every 2 weeks in order to avoid water and nutrient stress. They were used in experiments after they had grown to a height of 60-80 cm.…”

The objective of this study was to investigate the effect of different concentrations of methyl salicylate (MeSA) on direct defense and indirect defense in poplar cuttings (Populus × euramericana 'Nanlin 895'). Four defense-related enzyme activities, such as superoxide dismutase (SOD, EC1.15.1.1), oxydoreductases peroxidase (POD, EC1.11.1.7), catalase (CAT, EC1.11.1.6), and polyphenol oxidase (PPO, EC 1.14.18.1), were measured. The results showed that the SOD activities were induced by 1.0 and 10.0 mM MeSA and the POD activities were induced by MeSA. The CAT activity was induced at low concentrations of MeSA but was inhibited by high concentrations, and the PPO activity was affected by 0.1, 1.0, and 10.0 mM MeSA. Furthermore, the volatiles were detected using gas chromatography-mass spectrometry and gas chromatography. Twenty-one volatile compounds were tentatively identified in the emissions from plant leaves. Of these volatile compounds, (Z)-3-hexen-1-ol and cis-3-hexenyl acetate emissions were the highest. (Z)-3-Nonen-1-ol, (E)-2-hexen-1-ol, 1-octanol, (E,Z)-3,6-nonadien-1-ol, β-ionone, and hexadecanamide were six compounds that were only produced after treatment by 10.0 mM MeSA. These results showed that direct and indirect defense mechanisms in poplars were induced by MeSA.
