细胞质对植物抗(感)病虫的影响在不少植物中曾被研究。Meredith等(1979)发现夏威夷棉细胞质使叶跳虫数增加70％,但使烟草夜蛾幼虫的体重减少35％,因而认为棉花中可能具有某种起主导作用的细胞质系统,它有助于减少植物流行病的侵染和昆虫的危害。Raq(1980)指出玉米自交系CI21的核 The effects of cytoplasm on plant resistance to pests and diseases have been studied in many plants. Meredith et al. (1979) found that Hawaiian cotton cytoplasm increased the number of leaf hoppers by 70% but reduced the body weight of tobacco budworm larva by 35%, suggesting that cotton may have some dominant cytoplasmic system that helps reduce Plant epidemics and insect infestations. Raq (1980) points out the kernel of the CI21 maize inbred line
