2004-2005年对大叶补血草的物候期、植株形态、花形态、花粉特性、种子特性进行了研究,结果如下:大叶补血草3月底展叶,5月下旬现蕾,7-8月为开花期,8-9月为结实期。多年生草本,主根发达,肉质肥大且深,须根少。大型伞房花序,两性花,花萼宿存,是很好的鲜切花和干切花的材料。每花药有花粉粒156±22粒,花粉败育率为(9.7±4.3)%。P/O值为780,根据Cruden的标准推测大叶补血草属于兼性异交。种子千粒重0.397克,结实率68.9%。新鲜种子发芽率为(62±9)%,第二年三月种子发芽率为(97±2)%,说明种子有部分休眠现象,属于萌发异型性种子。
From 2004 to 2005, the phenology, plant morphology, flower morphology, pollen characteristics and seed characteristics of Limonium spp. Were studied. The results are as follows: For the flowering period, August to September for the fruiting period. Perennial herb, developed root, fleshy hypertrophy and deep, less fibrous roots. Large corymbat inflorescence, bisexual flowers, calyx persistent, is a good cut flowers and dried cut flowers material. Each anther pollen grains 156 ± 22, pollen abortion rate was (9.7 ± 4.3)%. P / O value of 780, according to the standard Cruden speculated that the big leaf Limonium is facultative sexual intercourse. Seed grain weight 0.397 grams, seed set 68.9%. The germination rate of fresh seeds was (62 ± 9)%, and the germination rate of the seeds in March of the following year was (97 ± 2)%, which indicated that the seeds had partial dormancy and belonged to germination atopy.
