人工栽培条件下三叶木通座果及果实生长特性研究

用栽培三叶木通为试材，研究了其座果及果实生长的特性。结果表明：人工栽培条件下，三叶木通座果（雌花）率可以提高到１３．５％，是野生三叶木通的２ １００％；以先年第１、２次攀援茎第３￣３０节位结果为主；３月底开花，花期３０ｄ左右。花后第２０￣５０ｄ（４月中旬至５月上旬）花序、雌花及幼果（子房）大量脱落，出现明显的脱落高峰。三叶木通果实纵向生长呈双Ｓ曲线布，生长期１５０ｄ左右，可划分成５个时期：受精结实

STUDIES ON FRUIT SETTING AND FRUIT GROWTH HABIT OF AKEBIA TRIFOLIATA UNDER ARTIFICIAL CULTIVATION

Fruit setting and the fruit growth habit of Akebia trifoliata were studied under cultivation. The results showed that the percentage of fruit setting reached 13. 5%under cultivation. Fruits set from the third to thirtieth nodes on one year-old branches.It flowered in the late of March and it's flowering stage was about 30 d. Heavy fruitfalling occurred in the second ten days of April and the first ten days of May. There were2S curves from blossom falling to maturity in fruit growth. The growth-period of fruit was about 150 d , when could be classified into five stages, i. e. fertilization, rapid-growing. slow-growing. fulling and premature growing. The results of generalized variance analysis showed that this division was both necessary and rational.
