- Abstract:
- ... Agrimonia eupatoria L. is an important medicinal plant of the Rosaceae family. Antioxidant and volatile components have been identified in this herb. The seed dormancy of A. eupatoria causes time-consuming germination with a low percentage. In this study, the effects of treatments including 4 °C wet cold (24 h and 48 h), seed coat removal, potassium nitrate (0.2 %, 1%, and 3%), and gibberellic aci ...

- Abstract:
- ... Most legumes are well-known for the physical dormancy of their seeds; hence, the implementation of appropriate scarification techniques is essential for introducing new legume crops within agricultural systems. This study investigated morpho-anatomical traits and dormancy-breaking requirements in two taxa of the genus Bituminaria: the widespread B. bituminosa and the point endemic B. basaltica. As ...

Drying characteristics and seed vigor were investigated at different RF electrode gaps (140, 150 and 160 mm). To better demonstrate the feasibility of applying RF-HAD on corn seeds, tempering-intermittent hot air drying (HAD) was studied as a comparison. Reduced electrode gap co ...

Seeds of three rapeseed cultivars (‘H61’, ‘H4815’, and ‘DK003’) were exposed to priming treatments and then their germination was tested at different water potentials. Seed priming improved the germination percentage, which was higher in ‘H4815’ than ...

Knowledge about flowering genes of fruit trees can help to conduct better molecular breeding programs. Therefore, this study was carried out to investigate the expression pattern of some flowering genes (FT, SOC1, CAL, LFY and TFL1) in Persian walnut (cv. Chandler) during the growing seas ...

- Abstract:

For Corylus avellana, pericarp permeability, seed desiccation tolerance, and the effect of warm and cold moist stratification combinations on germination and of outdoor sowing date on dormancy breaking and seedling emergence were investigated. Seeds with (intact fruit nut) and without the pericarp were subjected to an imbibition test, and water uptake was measured. After nuts had been stored for 5 ...

- Abstract:
- ... Stone fruit trees of genus Prunus, like other temperate woody species, need to accumulate a cultivar-specific amount of chilling during endodormancy, and of heat during ecodormancy to flower properly in spring. Knowing the requirements of a cultivar can be critical in determining if it can be adapted to a particular area. Growers can use this information to anticipate the future performance of the ...

The present study was conducted in order to determine morphological and physiological differences among heteromorphic seeds of M. denticulata in relation to dormancy and germination behaviour. Brownish black seeds with high moisture content were non-dormant and germin ...

- Abstract:

This study provided evidence that GA and the GA receptor GID1 (GA-INSENSITIVE DWARF1) are also needed for the embryo-to-seedling transition in Arabidopsis. The ga1-3 GA biosynthesis mutant fails to germinate unless GA is applied, whe ...

- Abstract:

The field grown tea bushes were subjected to treatment with dormancy breaking agents such as potassium nitrate (KNO₃), thiourea, sodium nitro prusside (SNP), the phytohormones kinetin (Kn) and gibberellins (GA). The efficacy of Kn and GA were comparatively lesser than KNO ...

Three varieties per year were considered: Spunta and ...

In tropical ecosystems, species with an impermeable seed coat, i.e. physical dormancy (PY), are large in number and their seed coat is considered to be an adaptive trait for species persistence and colonization. However, only little is known about their mechanisms for breaking dormancy. The objective of this study was to understand the importance of seed maturation site and burial location in dete ...

Due to a record low chilling accumulation in the winter of 2016–2017, many high-chill peach cultivars displayed almost no budbreak by mid-April of 2017 in central Georgia, USA, where budbreak usually occurs around mid-March. In this study, nine of these peach cultivars were used to study the effect of a late spring Dormex spray application (April 13, 2017) on subsequent budbreak, year-end cu ...
