Fruit abscission as a response to herbivory is well-documented in many plant species, but its effect on further damage by mobile herbivores that survive fruit abscission is relatively unstudied. Physalis plants (Solanaceae) abscise fruit containing feeding larvae of their main frugivore, Heliothis subflexa Guenée (Lepidoptera: Noctuidae), a specialist moth. We tested the ability of H. subflexa ...

The drought- and thermo-tolerant Quercus pubescens, a tree species growing on both acidic and calcareous soils in the sub-Mediterranean region, was exposed to soil drought (-60% to -80% soil water content) and air warming (+1.2 °C daytime temperature), singly and in combination. The experiment was conducted on two natural forest soils with similar texture but different pH (acidic and calcareous...

This paper reports mass spectra and linear temperature programmed retention indices (I(T)) for 31 esters of mono- and sesquiterpene alcohols with hydroxycinnamic acids. In this study, 14 phenylpropenoids were synthesized by esterification of terpenols with p-coumaric, ferulic, caffeic and sinapinic acids. Other phenylpropenoids were semi-quantitatively isolated by column chromatography from exu...

Background: Thymus is a widely used medicinal plant in food and pharmaceutical industries. Among different species of Thymus, T. vulgaris is used more than other species in therapeutic dosage forms. Objective: This study was conducted to differentiate various Thymus species by TLC fingerprint. Methods: In order to identify and differentiate various species of Thymus, TLC fingerprints of ess...

Native to Southern China, Ilex pubescens and Ilex asprella are frequently used in traditional Chinese medicine. Both of them produce a large variety of ursane-type triterpenoid saponins, which have been demonstrated to have different pharmacological effects. However, little is known about their biosynthesis. In this study, transcriptomic analysis of I. pubescens and comparison with its closely ...

Bamboo (Phyllostachys pubescens) expansion into adjacent forests is a widespread phenomenon in subtropical regions, and it has greatly changed the dominance hierarchy from trees to bamboos. This process may be accompanied by changes in productivity, nutrients accumulation and biogeochemical cycles. We compared the net primary production (NPP) and major pools and fluxes of nitrogen (N) in bamboo...

Eleven species of Mordellidae are newly recorded for New Brunswick, Canada. Six of these, Falsomordellistena discolor (Melsheimer), Falsomordellistena pubescens (Fabricius), Mordellistena ornata (Melsheimer), Mordellaria undulata (Melsheimer), Tomoxia inclusa LeConte, and Yakuhananomia bidentata (Say)are new for the Maritime provinces. Falsomordellistena pubescens is new to Canada. Pelecotoma f...

A homogenate-assisted vacuum-powered bubble extraction (HVBE) method using ethanol was applied for extraction of flavonoids from Phyllostachys pubescens (P. pubescens) leaves. The mechanisms of homogenate-assisted extraction and vacuum-powered bubble generation were discussed in detail. Furthermore, a method for the rapid determination of flavonoids by HPLC was established. HVBE followed by HPL...

Growth and biochemical performance of Manihot esculenta Crantz (TMS 0505) amended with Centrosema pubescens and NPK fertilizer were carried out. Contamination levels of 2%, 4%, and 6% were used while amelioration treatments C. pubescens and NPK 15:15:15 were carried out by adding organic supplement (decomposed Centrosema pubescens) and NPK at the rate of 0.25Kg per 5Kg of soil to the various le...
