Gladiolus (Gladiolus grandiflorus L.), a popular and economically profitable bulbous cut flower, has high demand in both Pakistan domestic and international markets on account of its attractive spikes, florets of huge forms, dazzling colors, varying sizes, and long vase life. However, its quality production is badly affected by non-uniform sprouting, poor crop stand, and old cultivars. To overc...

The phytohormone abscisic acid (ABA) regulates plant development and is crucial for abiotic stress response. In this study, cold storage contributes to reducing endogenous ABA content, resulting in dormancy breaking of Gladiolus. The ABA inhibitor fluridone also promotes germination, suggesting that ABA is an important hormone that regulates corm dormancy. Here, we report the identification and...

In order to evaluate low temperature tolerance of five variable somaclones as well as the cv. Peter Pears of gladiolus (Gladiolus grandiflorus Hort.) from which they were originated, catalase (CAT) activity and hydrogen peroxide (H2O2) level were measured. Before carrying out the analyses, vitroplants of these clones were exposed, during 21 days, to 8 8C temperature. In response to the stress g...

Crop production is inherently sensitive to climatic variations. Flowers have been admired and used by human to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of food. Gladiolus (Gladiolus grandiflorus Andrews; family Iridaceae) is an important bulbous cut flower grown all over the world. The present study was carried out to check the growt...

Fluorine (F) stands out for its phytotoxic potential, because it accumulates in plants, changes enzymes activity, reduces chlorophyll content and, consequently, affects growth and yield of crop plants. An experiment was conducted to evaluate the effects of F on leaf gas exchange in coffee and sweet orange plants, compared to sensitive (gladiolus) and tolerant (ryegrass) reference species. Plant...

Cormels of Gladiolus X gandavensis Van Houtte respond to heat shock by an induced synthesis of heat shock proteins. Synthesis of some of the non-heat shock proteins is concomitantly reduced. The ability of dormant cormels to synthesize heat shock proteins (hsps) and to repress the synthesis of non-hsps is greater than that of nondormant ones. A hsp of apparent molecular weight 68 kilodaltons is...

Sperm cells have been isolated from pollen tubes growing in style segments of the dicotlyledon Rhododendron macgregoriae and the monocotyledon Gladiolus gandavensis by the in vivo/in vitro method at various stages of fertilization. Pollen tubes emerged from the cut end of the style into agar medium, and more than 95% contained sperm cells. Sperm cells were released from the pollen tubes by osmo...

gladiolus is one of the flowers that used on cut flower and garden plants. an experiment was conducted to study the effects of chemical treatments on the vase life of gladiolus cut flower cv. ‘rose supreme’ with ten chemical treatment using complete randomize design with 3 replications. gladiolus cut flower was harvested when the 2-3 lowest bud had start showing color then cut flower were treat...
