tabaci, and induces accumulation of phytoalexin phaseolin in common bean hypocotyls. The green propolis ethanolic extract induces the formation of polyphenol oxidase and phenylalanine ammonialyase, with local and systemic effects in common bean plants, besides promoting a decrease in the area injured by bacterial blight.
This concentration reached 847.44 and 880.75 [micro]g per mL in soymilk made from soybean with 3-cm and 6-cm hypocotyls, respectively.
Several auxins were found to cause necrosis and death of hypocotyls of treated mung bean seedlings at a concentration of 10-3 M (Kollarovaet al.
Increased Agrobacterium-mediated transformation and rooting efficiencies in canola (Brassica napus L.) from hypocotyl segment explants.
The material (root, hypocotyl, cotyledons, epicotyl and eophyll) were fixed in glutaraldehyde (1% in 0.1 M phosphate buffer, pH 7.2) (Karnovsky, 1965) and later transferred to 70% ethyl alcohol following the protocol of Johansen (1940).
On the other hand, aerial part extract caused the highest percentages of growth inhibition in rootlets, when compared with hypocotyls. Similarly, root and seed extracts reached the higher percentage of inhibition on rootlets growth.
Then the air-dried maca hypocotyls were grounded into fine powder (to 75 [micro]m particle size) using a crusher and freeze-dried.
Paeonia lactiflora seeds display both hypocotyl and epicotyl dormancy and time from sowing to fully germination takes six to seven months under natural conditions.
Some researchers stated that somatic tissues of plants varied in terms of callus production and also cotyledon embryogenesis sensitivity was higher than hypocotyls [40, 41].
Statistical studies on anatomical modifications in the radicle and hypocotyl of cotton induced by NaCl.
According to previous studies of cotton tissue culture, callus culture can be initiated from different explants such as hypocotyls, radicals, tissues of embryo, shoot apex, cotyledonary leaves etc.
