INTRODUCTION An efficient and reliable method to estimate plant cell viability, especially of pollen, is important for plant breeding research and plant production processes. Pollen quality is determined by classical methods, like staining techniques or in vitro pollen germination, each having disadvantages with respect to reliability, analysis speed, and species dependency. Analysing single ce...

Six isolates of Botrytis cinerea were isolated from leaves and stems of different tomato varieties taken from four areas in the northwest of Algeria where tomato is mostly grown in greenhouses and high tunnels. The purpose of this research was to determine the effect of two salts, NaCl and CaCl2, on three stages of Botrytis cinerea's life cycle. All isolates tested were stimulated in 50 to 150 ...

The assumption that seeds imbibe most of the water required for germination as liquid through seed-to-soil contact has been a dominant theme in germination research and seeding technology. Under most conditions, seeds are also exposed to water vapour during imbibition, but the relative contributions of liquid and vapour are difficult to assess. In water uptake models that include vapour, proced...

Temperature is a major climatic factor that limits geographical distribution of plant species, and the reproductive phase has proven to be one of the most temperature-vulnerable stages. Here, we have used peach to evaluate the effect of temperature on some processes of the progamic phase, from pollination to the arrival of pollen tubes in the ovary. Within the range of temperatures studied, 20 ...

The protein metabolism of cotyledons attached to the embryonic axis has been compared with that in cotyledons removed from the axis at the initiation of a 6-day imbibition. Total protein declined in the attached but not in the detached cotyledons. Concurrent with the decline in protein level in the intact cotyledons there was an increased capacity to incorporate exogenously supplied leucine int...

Bioactive compounds, which are naturally produced in plants, have been concerned with the food and pharmaceutical industries because of the pharmacological effects on humans. In this study, the individual phenolics of six legumes during germination and antioxidant capacity from sprout extracts were determined. It was found that the phenolic content significantly increased during germination in ...

Most tree species in the temperate climatic zone (including Douglas fir) disperse seeds autumn. Some of them must be exposed to cold (0–10 °C) and moist conditions (cold stratification) overcome dormancy trigger germination. In Northern Hemisphere, winter warm spells occur more frequently last longer than recent decades from eastern Canada Europe. Our main research objective was investigate inf...

Brown rice has physical and sensory characteristics that are less favorable despite its high content of nutrition phytochemical. The germination process is one way to improve increase the acceptance brown rice. objective research was determine time varieties on chemical germinated conducted in RAL with 2 factors, (24, 48, 72 hours) (Mentik susu, Ciherang, Pandan wangi). data obtained were proce...

Seed thermoinhibition (inhibition of germination at warm temperatures) can reduce seedling emergence and stand establishment of cultivated lettuce (Lactuca sativa L.) when soil temperatures are warm (>25°C) at planting. Genetic variation for high temperature germination tolerance exists among accessions of lettuce and related wild species. Seeds of a L. serriola accession (UC96US23) germinated ...

Priming fresh and naturally aged canola seeds with different substances observing the seed germination properties are involved in this work. Fresh of cv. “süzer” were treated distilled water, -0.8 MPa polyethylene glycol (PEG) 6000 50 mM thiamine for 8 hours. Storage showed loss capacity compared to seeds. Present findings indicate that priming can improve speed both canola. Germination percent...
