It is well known that injury and infection by disease organisms may stimulate ethylene production by plant tissues (Williamson 1950; Burg 1962; McGlasson and Pratt 1964). The increased ethylene production which results from injury in fruit tissues may hasten the onset of a respiratory climacteric. This response, which has been observed in slices cut from three-quarter-grown cantaloupe fruit, may herald the commencement of physiological changes leading to natural ripening (McGlasson and Pratt 1964). However, in underground storage tissues, stimulated ethylene production may be concerned with the mechanisms of wound healing (Stahmann, Clare, and Woodbury 1966; Imaseki, Uchiyama, and Uritani 1968). The phenomenon of induced respiration in tissue slices of bulky underground storage organs has been known for many years (Laties 1967) and more recently it has been found to occur in sections or slices of other plant parts (ap Rees 1966). Palmer and McGlasson (1969) observed a similar rise in slices of green banana fruit which they considered to be a form of "induced" respiration.

Respiration (i.e., carbon dioxide production and oxygen consumption) increases as ripening is initiated in a group of harvested fruit called climacteric. This group includes many horticulturally important fruit crops, such as apples, avocados, bananas, melons, peaches, pears, and tomatoes. Other fruit, which includes cherries, citrus, and strawberries, do not exhibit an increase in respiration as they ripen and are called nonclimacteric. Measurements of carbon dioxide production by ripening apples, melons, and tomatoes revealed a well-defined climacteric, but only in harvested fruit. The respiratory climacteric was greatly diminished or absent from these fruit when they ripened while attached to the plant. Fixation of respired carbon dioxide through photosynthesis or into organic acids was insufficient to account for the diminished amount of carbon dioxide evolved from ripening attached climacteric fruit. Unlike the respiratory climacteric, an increase in ethylene production occurred in both attached and harvested climacteric fruit. Ethylene stimulates respiration in most plant tissues. The rapid rise in respiration as soon as attached ripening climacteric fruit were harvested or abscised suggests that an inhibitor of ethylene-stimulated respiration may be translocated from the plant and prevent the climacteric rise in respiration in attached ripening fruit.

Abstract This experiment was conducted in the Plant Tissue Culture Laboratory, College of Agricultural Engineering Sciences, University of Baghdad for the period from September/2018 to July 2019. The induced callus from the cotyledon leaves of seedlings of the Spilanthes acmella plant was used in order to know the effect of chemical catalysts and Starmedium was added to Glutamine (250, 300, 350) mgters on the chemical content. After 4 weeks of planting, the primary callus was planted at 150 mg in the nutrient medium supplemented with auxin,4-dichlorophenoxy acetic acid (2,4-D) 2.0 mg.L−1 and cytokinin Benzyl Adenine (BA) 0.5 mg.L−1 at constant concentrations in the first five medium, to which the catalyst was added salicylic acid at concentrations (25, 50, 75) μmol). The second medium was added to methyl jasmonate at concentrations (25, 50, 75 μmol) of the third medium was added to Casein hydrolysate at concentrations (25, 50, 75 μmol) of the fourth medium was added to Glutamine (250, 300, 350) mg. L−1. The results showed that the treatment of nutritional medium with high concentrations of stimulants and primer led to a significant increase in the content of plant tissues (the induced callus from the cotyledons) of total carbohydrates, the percentage of protein, the content of callus from the carotene pigment and content of proline, while the comparison treatment was the most effective in vegetable tissue contents of total carbohydrates and protein percentage and content of callus from the carotene pigment and proline, as well as this confirms that all treatments led to a positive and direct increase of chemical compounds content of plant tissues of chemical traits, especially in the treatment of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine, and phenylalanine (75 micromoles, 75 micromoles, 75 micromoles, 350 mg.L−1, 150 micromoles) respectively, were followed by the treatments of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine and phenylalanine (50 μmol, 50 μmol, 50 μmol, 300 mg.L−1, 100 μmol), respectively. The aim of this study is to know the effect of Salicylic acid, methyl jasmonate, casein hydrolysate, glutamine, and phenylalanine in the induction and differentiation of callus of cotyledon leaves cotyledon leaves of Spilanthes acmella seedlings on some chemical traits in vitro.
