Abstract
本試驗之目的在瞭解 Jojoba（Simmondsia chinensis 〔 Link 〕 Schneider ）植株生長習性及開花現象。結果顯示，在 50 株供試材料中，具生長習性為平伏式（ Prostrate ）者及多葉式（Leafy or compact ）者各 1 株，其餘 48 株均為開放式（ Open ）。葉之大小，形式及節間長度，各形式間都有顯著的差別。
休眠性雄花芽在種子萌芽後 7-8 個月即可形成。雌性休眠花芽約較晚 2-3 個月。不論是雄性或雌性的休眠性花芽，開花期概在寒冷之秋冬季節，未開花者則仍呈休態眠狀。
雄花的開花有二種迥然不同的現象：（1）在雄株的植株上先形成由數個花苞聚集在一塊之休眠性花芽而後在秋冬季開花。（2）每一花苞單獨形成，不呈聚集狀，無顯明的休眠期，開花後可顯明的看到花萼 5 片及雄蕊 8 枚。
The growth habits and flowering pattern of jojoba (Simmondsia chinensis (Link) Schneider) were observed in the green house at TARI, Taichung, during the period from 1980 to 1981. Three types of growth habit were found among 50 plants: One each of prostrate and leafy (or compact) types, and the rest open type. Leaf shape, leaf size and internode length on the main stem varied according to the different type of growth habit.
The dormant male flower buds appeared when plants were 7 to 8-months old, whereas the female ones formed 2-3 months later. Both male and female dormant flower buds blossomed only in autumn or winter and un-opened ones remained dormant.
Two types of blossoming were observed on male plants: (1) dormant flower buds formed in clusters and blossomed in autumn or winter and (2) single flower buds, with no dormant period, came in to full blossom with 5 sepals and 8 stamens.
