“…More than 70% of the variation for winter survival resulted from accession effects. However, the effect of environment and the environment by accession interaction were also highly significant indicating that winter survival varied among environments, a common result for complex traits such as winter survival (Zimmerman 1976).…”

“…Zimmerman (1973) found rosette duration is a function of photoperiod and temperatures, tends to be longer with lower temperatures and shorter photoperiods, and that genotypes vary in their response to photoperiod and temperature. Zimmerman (1976) also observed that the distinction between rosette and nonrosette habit can be arbitrary, and operates on a gradient influenced by genotype and environment. These complexities can be understood with additional studies of varying genetic material under controlled temperature and photoperiod regimes.…”

“…Zimmerman (1976) found that rosette habit duration, defined as the time to internode elongation, was controlled by a major gene, with perhaps several alleles, but also modified by other genes. The short rosette period appears to be dominant over a long rosette period (Imrie and Knowles 1970;Zimmerman 1976;Carapetian 2001). The genetic relationships among rosette duration, cold acclimation and winter survival are not clear and need additional study.…”

“…During the rosette stage, safflower is relatively resistant to cold temperatures (YazdiSamadi and Zali, 1979). The duration of this stage is not only dependent on environment but on heritable genetic traits (Zimmerman 1976;Zimmerman and Buck 1977). Ghanavati and Knowles (1977) found high cold tolerance in plants with a long rosette period collected from northwest Iran.…”

Johnson, R. C., Dajue, L. and Bradley, V. 2006. Autumn growth and its relationship to winter survival in diverse safflower germplasm. Can. J. Plant Sci. 86: 701-709. The relationship between several autumn growth traits and winter survival was determined in 11 diverse safflower (Carthamus tinctorius L.) accessions grown at Central Ferry and Pullman, WA, USA. The safflower was sown in September 2002 and 2003 and plant population counts were taken 6-8 wk after emergence, and after the last frost in the spring to calculate winter survival. Growth factors including plant habit and height were also measured in the autumn. The Pullman plots in [2003][2004] were lost during an usually cold and windy November, but otherwise survival ranged from 90% for BJ-27, an introduction from China, to zero for the cultivar Saffire. Winter survival was negatively correlated with more upright plant habit (r = -041**, n = 97) and plant height (r = -0.29**, n = 97). However, some accessions with low plant habit (prostrate growth) and low height values had relatively poor survival. The results show that BJ-27 has sufficient winter survival to achieve over-winter safflower production for many areas. Autumn plant habit and height can predict the potential for winter survival, but physiological factors related to cold acclimation appeared to determine if that potential is realized. La rusticité présente une corrélation négative avec un port plus dressé (r = -0,41**, n = 97) et la hauteur du plant (r = -029**, n = 97). Certaines obtentions à port bas (croissance prostrée) et de faible hauteur ont néanmoins mal survécu à l'hiver. Les résultats indiquent que BJ-27 est assez rustique pour survivre à l'hiver et croître dans de nombreuses régions. Le port et la hauteur du plant à l'automne donnent des indices sur la survie à l'hiver, mais des paramètres physiologiques associés à l'acclimatation au froid paraissent déterminer la réalisation de ce potentiel.

“…Analyses of the phenylthiohydantoin derivatives were performed by thin-layer chromatography (TLC) on polyamide sheets [27] and also by high-performance liquid chromatography (HPLC) on a pBondapak CI8 column (3.9 x 300mm) (Waters Associates) using a Jasco model TriRotor system equipped with a Uvidec-100 detector and Intelligent integrator model 5000E. Separation of the phenylthiohydantoins was carried out under the conditions described by Zimmerman et al [28]. If necessary, thiazolin;ne derivatives were hydrolyzed in 5.7 M HCI containing 0.1 4 SnC1, in sealed and evacuated vials at 150 "C for 4 h and the resulting free amino acids were analyzed on the amino acid analyzer ~9 1 .…”

The complete amino acid sequence (72 amino acid residues) of a double-headed proteinase inhibitor from seeds of Vicia angustifolia L. var. segetalis Koch has been determined and compared with those of other double-headed inhibitors of known structure. Sequencing was performed by conventional methods with the aid of the fragments produced by reduction and S-carboxymethylation of the enzymatically modified inhibitors, and also using tryptic and chymotryptic peptides.The positions of the 14 half-cystine residues agreed among all the reported primary structures of the legume double-headed inhibitors. However, V. angustifolia inhibitor possessed extensive amino acid differences compared to the others. The phylogenetic relationship among these inhibitors was established using the unweighted pair-group method and revealed that the V . angustifolia inhibitor and the peanut inhibitor B-I11 had diverged at a relatively earlier stage compared to the other inhibitors. The inhibitor consists of 72 amino acid residues and inhibits both trypsin and chymotrypsin. As shown for the other proteinase inhibitors [6], limited hydrolysis at either reactive site also occurs in V . angustifolia inhibitor by attack of the corresponding enzyme under acidic conditions [7,8]. However, in constrast to the others, an additional cleavage other than that of the antitryptic site was observed during the incubation of the inhibitor with trypsin at pH 3 [9].Using the fragments produced by reduction and S-carboxymethylation of the enzymatically modified derivatives and also using tryptic and chymotryptic peptides, the complete amino acid sequence of the inhibitor has been determined. The result is compared with those of the other doubleheaded inhibitors whose primary structures have been reported [lo -211 and the phylogenetic relationships between them are discussed. MATERIALS AND METHODS MaterialsVicia angustifolia inhibitor was prepared as reported previously [5]. Bovine a-chymotrypsin (Boehringer) was treated with N-tosyl-L-lysine chloromethyl ketone (TosLysCH,CI) [22] (Nakarai Chemicals, Japan) and purified by passing through a column of lima bean proteinase inhibitor linked to Sepharose 4B which was prepared by the method of Knights and Light [23]. DEAE-Sephadex A-25 and DEAE-Sephacel were obtained from Pharmacia Fine Chemicals. Polyamide thin-layer sheets were from Cheng Chin Trading Co. Preparation of enzymatically modified inhibitor derivatives and their fragmentsAll the inhibitor derivatives produced by the limited hydrolyses of the inhibitor by either trypsin or chymotrypsin, are schematically presented in Fig. 1 as well as their fragments separated after reduction and S-carboxymethylation. Details of the preparations, isolations, and partial sequence determinations of the trypsin-modified derivatives have been described previously [7,9]. The chymotrypsin-modified inhibitor (CmV) was prepared at pH 3 with a catalytic amount of chymotrypsin under similar conditions to those of the trypsinmodified derivative, TmV-I [7]. After the reduction...

The development of winter‐tolerant safflower genotypes is crucial for the improvement of global safflower agriculture. The aim of the present study was to determine the cold tolerance abilities and some agricultural characteristics of advanced safflower genotypes. For this purpose, 10 advanced safflower genotypes were used in four different locations. The experimental design was a randomized complete block design with three replications. Winter survival and agricultural characteristics were significantly affected by growing season, location and genotype. Winter survival varies between 86.43% and 93.91% among the genotypes which is promising for winter sowing. As the average of 2 years, the highest oil content (36.25%) was observed in genotype EC21 and it was followed by genotypes EC11 (35.51%) and EC20 (35.49%). As with the seed yield, the high winter survival of genotypes with high oil content is highly promising in terms of winter sowing. Safflower should be grown in winter with mild temperature regions for high seed yield and sustainable safflower production. Therefore, this study focused on winter‐tolerant genotypes that are superior one in terms of seed yield and oil content.
