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Abstract Information in the literature and unpublished results of authors on Dobinea were used to determine kind [class(es)] seed (true + endocarp) dormancy non-dormancy genera all five tribes Anacardiaceae,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...

Leaf yellowing or petal senescence is the main postharvest disorder for many cut flowers. Plant hormones such as cytokinins are able to inhibit leaf yellowing in some cut flowers and potted plants. In our experiments, we applied thidiazuron aiming to delay leaf yellowing and 1-methylciclopropene (1-MCP) for inhibiting flower senescence of cut stock flowers during vase life. Cut flowers were pul...

Coconut palms from the Grand-Lahou region of Côte d’Ivoire exhibiting lethal yellowing-like symptoms and infected by a phytoplasma were further tested for the characterization of the phytoplasma pathogen based on the 16S rRNA gene analysis. Nested PCR with phytoplasma universal and lethal yellowing-specific primers resulted in amplification of products of expected sizes from seven out of 17 sym...

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...

Specimens of Ruppia from all eleven Nebraska counties in which it is known fall into two groups: R. occidentalis in alkaline Sandhills waters and R. maritima in saline waters of the Platte River Valley and Lancaster County. Ruppia occidentalis is distinguished by its more robust size; redspotted leaves and stems; terete, entire, obtuse leaves; 4-8(9) carpels; and by two elliptic white spots on ...

Short-wavelength-sensitive (SWS) resolution acuity has been reported to be limited by the density of the responding ganglion cells for people without appreciable age-related lenticular change. This study measured the robustness of SWS-cone acuity and contrast sensitivity (CS) to simulated lens yellowing and opacification. Resolution acuity at 8 deg eccentricity proved robust to significant amou...
