Arundinella hirta is a herbaceous rhizome plant showing a clonal growth habit. Ramets may live for eight years and their rhizomes persist after the death of the above-ground tissues. Ramets of Arundinella hirta belonging to four generations. There are five different forms of translocation of photosynthate among ramets in clonal Arundinella hirta, and basic translocation patterns are apical translocation, basipetal translocation and horizontal translocation. In apical translocation, photosynthate only can be exported into vegetative ramets and cannot into flowering ramets, i.e., this translocation appears to have repellency and affinity which occur in photosynthate translocation between ramets. In basipetal translocation photosynthate only can be exported into flowering generating ramets and cannot into vegetative ramets, similarly, the translocation also appears to have repellency and affinity. In horizontal translocation between same age -generation ramets, only can export photosynthate into the opposite sex ramets, that is to say, horizontal translocation show the opposite sex attractability between sister ramets.
