摘要: Flea beetle is an important pest accounting for 25 % foliage damage in spider plant. The reported manifested as "shot holes'' variable among the plant morphotypes. study aimed at determining inflicted on three main morphotypes relation to metabolites. Three were propagated inside a screen house completely randomised design (CRD) and flea beetles introduced seventh week of growth determine caused assessed using Bailey scoring scale (0-3, 4-7 >7 holes/leaf). Data was log transformed analysed analysis variance (ANOVA). means separated protected least significant difference (LSD0.05). Quantitative determination primary secondary metabolites done taken before infestation. Proximate Kjedahl methods used carbohydrates proteins respectively. Determination vitamins chromatography. purple stemmed morphotype most damaged (8.6, p≤0.05), green (2.7, while purple-green moderately (7.6, p≤0.05). There Purple had highest carbohydrates, proteins, glucosinolates but terpenoids terpenoids. susceptible susceptible. largely metabolomically influenced that levels antagonistic It can be recommended that, breeders use improve resistance more nutritious order increase yield maintain nutritional potential. Also farmers grow infested fields.
