The study consisted of testing the effects of four different growth media （Clay, Loam, Clay ＋ sheep manure （1：1） and Loam ＋ sheep manure （1：1） as volumetric rates on vegetative and flowering growth characters of five different cultivars of Hyacinths plant （Blue Giant, City of Haarlem, Jon Bos, Delf Blue and Fondante）. The experiment was laid out in randomized complete block design （RCBD） of two factors in three replicates. Media mostly affected the parameters studied during the experiment. Early emergence （22.53 days） and flowering （73.13 days） was recorded in medium consisting of loam and sheep manure, while maximum plant height （19.75 cm）, leaves number （6.13）, leaf area （31.47 cm2） were recorded in clay medium. Maximum number of florets plant-l （31.93） and spike length （7.95 cm） were recorded in medium consist of clay and sheep manure. Maximum length of spike stem （9.61 cm） and total chlorophyll percentage （53.45%） were recorded for loam medium. Among the cultivars, some parameters showed significant variation. Early emergence （20.42 days）, maximum plant height （20.35 cm）, leaf area per plant （33.01 cm2） and length of spike stem （15.10 cm） were given by cv. Fondante. Maximum number of florets plantl （35.58） and spike lengths （8.63 cm） were recorded by cv. Blue Giant. High percentage of total chlorophyll （58.15%） was recorded in cv. Jon Bos..展开更多

Sequence analysis showed that this gene was homologous to AGAMOUS. Northern hybridization indicated that HAG1 was specifically expressed in floral organs using 3’ end of HAG1 as a probe. Further, transcript of this gene was not detected in differentiating tepals induced by lower concentration of hormones, however, it was detected in differentiating stemans by higher concentration of hormones in vitro. It is possible that there is a close relationship between the concentration of hormones, homeotic genes and identities of floral organs.展开更多

The maximum survival percentage, plant height （cm）, root length （era）, numbers of roots and root weight per cutting were significantly higher in hard wood cuttings. IBA concentration had no speculative effect on plane tree cuttings. Thus, hard wood cutting was the best choice for plan tree propagation.展开更多
