The effect of pectic oligomers and 1-aminocyclopropane carboxylic acid on ethylene biosynthesis and color change was studied in ripening tomato pericarp discs excised from mature-green tomato fruit (Lycopersicon esculentum Mill.). Pectic oligomers induced at least four distinct responses when added to pericarp discs: (a) a short-term, transient increase in ethylene biosynthesis; (b) a long-term...

Calamus erectus Roxb. (CE) fruit under the family Arecaceae is traditionally used by the local people of Darjeeling Himalaya as an antidiabetic agent but no scientific reports are available yet. Hence this study was designed to determine the in vitro antioxidant and antidiabetic activities of two different parts viz. mesocarp and endocarp of Calamus erectus fruit. The extracts were screened for...

Extensive studies on the dry fruits of the model plant arabidopsis (Arabidopsis thaliana) have revealed various gene regulators of the development and dehiscence of the siliques. Peach pericarp is analogous to the valve tissues of the arabidopsis siliques. The stone (otherwise called pit) in drupes is formed through lignification of the fruit endocarp. The lignified endocarp in peach can be sus...

BACKGROUND AND AIMS Identification of Prunus groups at subspecies or variety level is complicated by the wide range of variation and morphological transitional states. Knowledge of the degree of variability within and between species is a sine qua non for taxonomists. Here, a detailed study of endocarp dimension and shape variation for taxa of Prunus section Prunus is presented. METHODS The s...

In this study, I tested the effect of Syagrus loefgrenii nut number on the removal intensity by rodents across seasons. Also, I assessed both S. loefgrenii fruit production, and dispersion pattern to analyze the relationship between these parameters and nut removal. Trials were performed (autumn, winter, spring, and summer), in which endocarps were placed inside trays (5, 15, and 40 endocarps) ...

Calcium deficiency causes Endocarp Lesion disorder in pistachio nut. To investigate the effects of various calcium treatments on Endocarp Lesion disorder and some nut qualitative characteristics in Pistachio cv. Akbari, an experiment was done in completely randomized design with four treatments (1- control treatment, 2- calcium chelate foliar spray, 3- calcium nitrate and 4– calcium sulfate (gy...

Time course studies indicate that auxin prevents senescence of excised bean endocarp (Phaseolus zvlgaaris, L.. var. Kentucky Wonder pole beans) through an effect on metabolism of RNA. Firstly, during aging of tissue sections in absence of auxin degradation of RNA precedes degradation of DNA and protein: these degradations are prevented by auxin (4, 5, /7).. Secondly, during short (2-hr) incubat...

Abstract Information in the literature and unpublished results of authors on Dobinea were used to determine kind [class(es)] seed (true + endocarp) dormancy non-dormancy genera all five tribes Anacardiaceae, examined relation taxonomic position endocarp anatomy within family. Reports both germination found for 15 tribe Spondiadeae, 6 Anacardieae, 30 Rhoeae, 3 Semecarpeae 1 Dobineeae. In Spondia...

A field experiment was conducted during two consecutive growing seasons to determine and quantify the growth response of the olive (Olea europaea L. cv. Leccino) fruit and of its component tissues to tree water status. Pre-dawn leaf water potential (Psi(w)) and fruit volume were measured at about weekly intervals, and fresh weight (FW) and dry weight (DW) of the fruit tissues at 15, 20 and 21 w...
