a two year field experiment was carried out to evaluate the competitive effects of wild mustard densities growing with rapeseed (cultivar talaye) under different nitrogen rates. treatments were wild mustard densities (0, 10, 20, 30, and 40 plant m-2) and nitrogen (n) rates (0, 50, 100, 150, and 200 kg n ha-1). the factorial set of treatments was arranged into a randomized complete block design ...

in order to study the response of wheat (triticum aestivum) cv. chamran and wild barley (hordeum spontaneum) to different herbicides, a pot dose response experiment was conducted in a completely randomized design with three replication at research greenhouse of ferdowsi university of mashhad in 2008. different doses of herbicides including clodinafop propargyl, pinoxaden, sulfosulfuron, and met...

On Page 1428, Table 5 is missing. It should be placed after this paragraph “In study, a total of 19 endemic species Borneo were recorded (Table 5). The highest number was found in S1 followed by S2 and S3. Four Dipterocarpaceae (Shorea crassa at S2; Shorea isopteran, parvistipulata Vatica micrantha S1) study area Three each from Fagaceae, Lauraceae Myrtaceae also documented during At similar el...

To study the effects of applied nitrogen levels and wild mustard densities on the growth of wheat and wild mustard, a field experiment was conducted at Re-search and Experimental Field of Islamic Azad University of Ahvaz-Iran. The effects of three nitrogen levels namely 90, 150 and 210 kg.ha-1 and four wild mustard densities such as 0, 5, 10 and 15 plants.m-2 were evaluated in split plot arrang...

Research into biological control of Mikania micrantha Kunth (Asteraceae) started in 1978, concentrating on insect agents. Host specificity studies on the first agent, Liothrips mikaniae (Priesner) (Thysanoptera, Phlaeothripidae) from Trinidad were completed by 1982, and the thrips was released in the Solomon Islands in 1988 and, subsequently in Malaysia in 1990. Neither release led to establish...

to assess the genetic relationships between 72 cultivated and 65 wild grapevines in west azerbaijan and in kurdistan, 19 ssr markers were employed. microsatellitic primer pairs amplified, a total of 163 alleles with an average of 8.6 alleles/locus (for cultivars) and 153 alleles with an average of 8.05 alleles/locus (for wild samples). the expected heterozigosity varied from 0.7 in cultivars to...

A phytochemical study on the aerial parts of Mikania micrantha led to the isolation of two new phenolic compounds, benzyl 5-O-β-d-glucopyranosyl-2,5-dihydroxybenzoate (1) and (7S,8R)-threo-dihydroxydehydrodiconiferyl alcohol 9-acetate (2), together with twelve known compounds, benzyl 2-O-β-d-glucopyranosyl-2,6-dihydroxybenzoate (3), 4-allyl-2,6-dimethoxyphenol glucoside (4), (+)-isolariciresino...
