Seed dormancy is modulated in recently evolved chlorsulfuron-resistant Turkish biotypes of wild mustard (Sinapis arvensis)
Biotypes of the broad-leaved wild mustard (Sinapis arvensis L.) found in wheat fields of Aegean and Marmara region of Turkey were characterized and shown to have developed resistance to sulfonylurea (chlorsulfuron), an inhibitor of acetolactate synthase (ALS). DNA sequence analysis of the ALS genes from two such resistant ("R") biotypes, KNF-R1 and KNF-R2, revealed point mutations, CCT (Pro 197...
متن کاملAssessment of Wild Mustard (Sinapis arvensis L.) Resistance to ALS-inhibiting Herbicides
There is an urgent need for rapid, accurate, and economical screening tests that can deter‐ mine if weeds surviving a herbicide application are resistant. This chapter describes de‐ velopment and application of a simple root length bioassay technique for detection of wild mustard (Sinapis arvensis L.) resistance to ALS-inhibiting herbicides. This bioassay was performed in 2-oz WhirlPak® bags fi...
متن کاملMetabolism-based resistance of a wild mustard (Sinapis arvensis L.) biotype to ethametsulfuron-methyl.
Under controlled-environment conditions, ethametsulfuron-methyl doses that inhibited growth by 50% (ED(50)) were >100 and <1 g of active ingredient (ai) ha(-)(1) for ethametsulfuron-methyl-resistant (R) and -susceptible (S) wild mustard, respectively. There were no differences between the two biotypes with regard to absorption and translocation of the herbicide. Three days after treatment, appr...
متن کاملCompetition between Wild Mustard (Sinapis arvensis L.) and Wheat (Triticum aestivum L.) under Different rate of Nitrogen
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...
متن کاملEffect of seed storing temperature on germination of wild mustard (Sinapis arvensis) seeds
Seed dormancy of wild mustard (Sinapis arvensis) could be changed through seed storing. The seeds were collected from four regions: Fars, West Azarbaijan, Khuzestan and Mazandaran provinces. They were stored at three different temperatures (-18, +3 and 22-25°C) for 3, 6, 9, 12 and 15 months. They were then put under suitable condition for germination. Mean germination time for seeds was measure...
