seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...

anastrepha bezzii (diptera: tephritidae) larvae are common inside fruits of sterculia chicha (malvaceae) in minas gerais state, brazil. the seed dormancy and attack by a. bezzii of the native species s.chicha can be detrimental to seed germination and thus the natural spread of this plant. the objectives of the current study were to compare ecological observations of a. bezzii and s. chicha in ...

The knowledge about aspects related to seed germination are extremely important the propagation of Passiflora species. Considering diversity species and need studies that can elucidate process seeds this study aimed was evaluate methods overcome dormancy in two (P. morifolia P. cincinnata) by pre-germinative treatments as physical scarification, immersion gibberellic acid (GA3) Promalin® (GA4+...

dormancy of eastern dodder and african rocket seeds makes the controlof them very difficult in orchards and farms. in order to study the effective factors in dormancy breaking of these two weeds species, a factorialexperiment based on crd with three replications was conducted at the research laboratory of birjand faculty of agriculture in 2008 and 2009. treatments were: control, soaking in sulf...

The objective of this study was to evaluate seed metrics, optimum temperature for germination and efficiency five pre-germination treatments overcoming dormancy Caesalpinia ferrea seeds. Seeds were subjected constant temperatures 15, 20, 25, 30 35°C the following treatments: nicking with pincers; immersion in water 24 hours at room temperature; scarification sandpaper; caustic soda 60 minutes; ...

three experiments were conducted in tissue culture and biotechnology laboratory of horticulture department of mohaghegh ardabili university in 2012. for the regeneration of plant from seed, different concentrations of naoh (5, 10, 15, 20 m) and various scarification methods with sandpaper (soft scarification, medium scarification and hard scarification) were used based on completely randomized ...

This research aims to evaluate the effects of seed scarification on five perennialAstragalus species including A. effusus, A. vegetus, A. subsecundus, A. brevidens and A.cyclophyllon in the field conditions. Seeds were sown after scarification with sandpaper byhand in the field of Homand Absard Rangeland Research Station, Damavand, Iran in autumnin 2008. The seeds were sown using split plot des...
