Abstract: | Requirement for endogenous ethylene during seed germinationof the following ten species was determined: Lycopersicon esculentumMill, (tomato), Allium cepa L. (onion), Avena fatua L., dormantpure line AN-51 (wild oats), Cucumis sativus L. (cucumber),Sinapis arvensis L. (wild mustard), Tagetes erecta L. (marigold),Raphanus sativus L. (radish), Triticum aeslivum L. (wheat),Catharanthus roseus L. (periwinkle), and Phaseolus aureus L(mung bean). Experiments were done under controlled conditionssuited for the germination of each species. Criteria used todetermine the need for endogenous ethylene were: (i) temporalrelationship between ethylene production and seed germination;(ii) parallel inhibition of ethylene synthesis and seed germinationby L- |
