to study the effects of chilling on dormancy breaking and the increased germination characteristics of nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. factor a was the chilling treatment in three levels (control, one-month and two-month ...

BACKGROUND AND AIMS Silene dioica and S. latifolia experience only limited introgression despite overlapping flowering phenologies, geographical distributions, and some pollinator sharing. Conspecific pollen precedence and other reproductive barriers operating between pollination and seed germination may limit hybridization. This study investigates whether barriers at this stage contribute to r...

Pre-dispersal seed predation can greatly reduce crop size affecting recruitment success. In addition, non-fatal damage by seed predators may allow infection by fungi responsible for post-dispersal seed losses. The objectives of this study were (1) to quantify pre-dispersal seed predation and fungal infection in a Neotropical tree species, Luehea seemannii, that produces dehiscent fruits and win...

Abstract This study aimed to evaluate the effect of fruit maturation stages and pre-germination treatments with plant regulators on physiological quality seeds cv. BRS Mel do Cerrado. Two experiments were carried out, germination emergence, installed in a completely randomized design 3 x 2 factorial arrangement, three (1-partially ripe fruits; 2-fully fruits 3-senescent fruits) two (1. [GA4+7 +...

The effect of pre-sowing magnetic treatments was investigated on germination, growth and yield of okra (Abelmoschus esculentus cv. Sapz pari). The dry okra seeds were exposed to sinusoidal magnetic field induced by an electromagnet. The average magnetic field exposure was 99 mT for 3 and 11 min and seeds with no magnetic field treatment were considered as control. Both treated and non-treated s...

ABP41 is identified as a novel member of plant villin/gelsolin/fragmin superfamily proteins from lily pollen, which binds stoichiometrically to actin filaments and severs them in vitro. To further understand its in-vivo function and the potential molecular mechanisms, biochemical analysis, fluorescence microscopic observation and microinjection assays were performed. Different biochemical measu...

Bermudagrass (Cynodon dactylon) is one of the most frequently-used turfgrasses for golf, sport, and recreational turf throughout tropical, subtropical, and transition zone regions of the world. Recently, a number of seeded bermudagrass cultivars have been released into the turfgrass market and are quickly becoming a popular option for turfgrass managers. A major limitation with these seeded ber...

Tests of the germination response of light sensitive Lepidium virginicum seeds to applied gibberellic acid confirmed earlier reports that gibberellic acid can substitute for red light. Further tests indicated that promotion of germination by either red light or gibberellic acid can be nullified by abscisic acid. Dark incubation of the seeds in kinetin alone resulted in only slight promotion of ...

Salinity is an important problem all over the world. The destructive effect of salinity observed from seed germination stage. In this study, it was aimed to determine on medically Satureja thymbra L., whether pre-treatments are a factor in breaking stress, and level tolerance species. research, firstly, seeds were exposed two (80°C (5 minutes) + 10 ppm GA3 (24 hours), 80°C 100 hours)) then 8 di...

This paper presents the results of an experiment on effect cold plasma (He+O2 or He+Air) pre-sowing stimulation seeds Wolska cultivar onion process their germination. Four groups characterized by different exposure times (60, 120, 240 and 480 s) were used. Untreated used as a control. The distance between electrode tested material was 50 mm. Pre-sowing improved germination parameters such capac...
