“…The layer of the epicuticular waxes may contain aliphatic components, sugars and amino acids (Eigenbrode and Espelie, 1995;Niemietz et al, 2009;Yin et al, 2011;Haliński et al, 2012), as well as secondary metabolites (Schoonhoven et al, 2005;Städler and Reifenrath, 2009;Supapvanich et al, 2011). The roles of primary and secondary com-pounds on aphid feeding and probing behaviour have been studied for decades.…”

“…Plant epicuticular waxes are complex mixtures of long chain aliphatic and cyclic components including fatty acids, hydrocarbons, alcohols, aldehydes, ketones, β-iketones and esters, as well as low levels of terpenoids, sterols, flavonoids, and phenolic substances. This layer may also contain sugars, amino acids and secondary plant substances such as glucosinolates, furanocumarins and alkaloids (Eigenbrode and Espelie, 1995;Schoonhoven et al, 2005;Städler and Reifenrath, 2009;Haliński et al, 2012;Supapvanich et al, 2011). The morphology as well as the composition of EW vary widely between species or cultivars and are also affected by the plant age and certain environmental factors, such as heat, humidity and irradiance levels.…”

The electrical penetration graph (EPG) method was used to quantify the effect of surface waxes on probing behaviour of the grain aphid Sitobion avenae F. (Hemiptera: Aphididae). The experiments showed that wax removal significantly affected probing behaviour of S. avenae. Generally, the aphids feeding on the plants without wax had a shortened non-probing (EPG-pattern np) and prolonged penetration of peripheral tissues -epidermis and mesophyll (EPG-pattern C). The EPG tests also showed that the three tested extracts of surface waxes from waxy plants RAH 122 were active as aphicides against the grain aphid.K Ke ey y w wo or rd ds s: Epicuticular wax, peripheral tissues, epidermis, mesophyll, triticale, Sitobion avenae, EPG, artificial diet ACTA BIOLOGICA CRACOVIENSIA Series Botanica 57/1: [95][96][97][98][99][100][101][102][103] 2015

Growth, Yield and Postharvest Quality of Wax Apple as Affected by Naphthalene Acetic Acid Application

-Results of this study represent the first report of the effect of Naphthalene Acetic Acid (NAA) on the pre and post harvest quality of wax apple fruit. The wax apple trees were spray treated with 0, 5, 10 and 20 mg L -1 NAA under field conditions during 2008 to 2011. The experiments were carried out in Completely Randomized Design (CRD) with six replications. Leaf chlorophyll content, chlorophyll fluorescence, photosynthetic yield, net photosynthetic rate, drymatter content of leaves and total soluble solids and K + content of wax apple fruits were significantly increased after treatments with 10 mg L -1 . Polygalacturonase activity significantly decreased with NAA treatments. The application of 5 mg L -1 NAA increased 27% more bud and reduced 42% less fruit drop compared to the control. In addition, higher protein and phosphate synthase activity of leaves, fruit set, fruit growth, larger fruit size and yield were recorded in NAA treated plants. In storage, treated fruits exhibited higher TSS and firmness and less weight loss, browning, titratable acidity, respiration and ethylene production than the control. It is concluded that spraying with 5 and 10 mg L -1 NAA once a week under field conditions produced better fruit growth and yield of the wax apple and maintained better fruit quality in postharvest storage. Index terms: NAA, fruit, development, pre and postharvest quality.

The aim of this study was to evaluate the effect of different xanthan gum coatings with nanoparticles (nanocapsules and nanospheres) on the production and oxidation of phenolic compounds generated by enzymatic activity (phenylalanine ammonia lyase (PAL) and polyphenol oxidase (PPO)) on fresh-cut Red Delicious apples stored for 21 days at 4°C. The nanoparticles were prepared using the emulsification-diffusion method. The film systems formed had particle sizes (Ps) of 190 to 260 nm, the polydispersity index (Pdi) was<0.3+, and the zeta potential was (ζ)>|35|mV parameters that suggest good physical stability. While all the nanoparticulate coatings proved to be effective, the best coating was the nanocapsules/xanthan gum combination because it decreased the initial respiration rate by 63 % compared to controls. The effect on PPO and PAL activity was associated with the protection of phenolic compounds, whose concentrations remained unchanged. Also, lower variations in total color differences were found.
