Four species of ceratiodes were studied about organic morphology and embryonal development and biological characteristics . the results were showed as follows : c . arborescens and c . ewersmanniana were more dominant than c . latens and c . lanata in spire and vegetative period . in flowering phase of male flower , c . arborescens and c . latens arrive the maximum peak of flowering during 8 : 00 - 11 : 00 . c . lanata arrive the maximum peak of flowering during 11 : 00 - 1 : 00 , but in flowering phase of female flower , three species arrive the maximum peak of flowering in 14 : 00 ; temperature of female flower was righter than one of male flower 本文對駝絨藜屬4種植物進(jìn)行了器官形態(tài)學(xué)及解剖學(xué)、胚胎發(fā)育及生物學(xué)特性的研究,結(jié)果表明: 4種材料幼苗期和營養(yǎng)生長期的生長狀況均是華北駝絨藜、心葉駝絨藜比駝絨藜、北美駝絨藜占優(yōu)勢;開花規(guī)律,華北駝絨藜和駝絨藜雄花均在8 : 00 - 10 : 00達(dá)開放高峰,北美駝絨藜在11 : 00 - 1 : 00達(dá)開放高峰,而三者雌花均在14 : 00左右達(dá)開放高峰。
