Some advances have been obtained with studies on alterations of the culture medium with activated charcoal, gibberellic acid
, lauric acid, among others, in addition to gene expression in somatic embryogenesis.
CHEMICAL SCARIFICATION AND USE OF GIBBERELLIC ACID
FOR SEED GERMINATION OF BLACKBERRY CULTIVARS (Rubus glaucus BENTH)
In order to potentiate and standardize the germination of pequi by the seminal route, different techniques have been used, including the removal of germination inhibitory coatings, seed scarification, and use of gibberellic acid
(BERNARDES et al., 2008; LEAO et al., 2012).
The influence of the plant growth regulator gibberellic acid
(GA3) on the hemolymph contents of Galleria mellonella (Lepidoptera: Pyralidae) was examined.
is an important plant hormone that regulates growth, cell division, and seed germination.
To achieve this, use of freshly harvested garlic clove seed as a planting material after treating with low temperature storage, clove topping and gibberellic acid
would be imperative.
