Effect of High Temperature Stress on Pollen Grains in Sunflower (Helianthus annuus L.) Inbred Lines
نویسندگان
چکیده
HIGHLIGHTS Pollen grains of ten sunflower inbred lines were evaluated under normal and high temperature stress conditions. Two treatments three treatment times used as factors viability, pollen germination percentage tube length decreased with increasing time period. RL-86 ORI-73 showed excellent ability to withstand stress.

Cytomorphological and molecular diversity in backcross-derived inbred lines of sunflower (Helianthus annuus L.).
A set of 250 distinct, stable, and uniform backcross-derived inbred lines were developed in sunflower through 5 interspecific cross combinations involving 4 wild diploid annual species (Helianthus argophyllus, H. petiolaris, H. annuus, and H. debilis). The presence of the wild-species genome in these inbred lines was confirmed through higher chromosome associations (tri- and quadrivalents) at d...
متن کاملData on mass spectrometry based identification of allergens from sunflower (Helianthus annuus L.) pollen proteome
Allergy is a type of abnormal immune reactions, which is triggered by environmental antigens or allergens and mediated by IgE antibodies. Now-a-days mass spectrometry is the method of choice for allergen identification based on homology searching. Here, we provide the mass spectrometry dataset associated with our previously published research article on identification of sunflower pollen allerg...
متن کاملChemical composition of the ‘low quality’ pollen of sunflower (Helianthus annuus L
The nutritional needs of bees are receiving renewed attention in the context of declining bee populations and changes in land use that threaten floral resources. We present a comprehensive analysis of the nutritional composition of sunflower (Helianthus annuus) pollen, comparing hand-collected, bee-collected and stored pollen. As found in previous studies, the protein content of sunflower polle...
متن کاملMorphological and molecular responses of sunflower (Helianthus annuus L.) lines to drought stress
Drought stress is a serious adverse factor limiting growth and productivity of sunflower. Evaluation of defense systems is important for producing resistant cultivars. In this study, some agro-morphological and molecular characteristics of six sunflower lines were evaluated under normal and irrigation at 40 and 60% of field capacity in randomized complete block design (RCBD). The results showed...
متن کاملEffects of Salinity, Temperature, and Polyethylene Glycol on the Seed Germination of Sunflower (Helianthus annuus L.)
Salinization has severe influences on agriculture in the whole world. The main aims of this work were to evaluate osmotic effect and ion effect of NaCl on seed germination of three sunflower (Helianthus annuus L.) cultivars interacting with three alternating temperature regimes and to select the most salt tolerant cultivars to plant in the saline region. Seeds were germinated in the isotonic Na...
