Studies on the effects on the growht, yield, quality with different planting densities of the watermelon variety zhonghuaquanwang results that the best planting density is 500 individual plants in 667 m ^ 2 area with 3 stems of the grafted individual
摘要研究不同種植密度對于中華拳王西瓜生長、產量、品質等影響,結果表明,中華拳王嫁接西瓜採用三蔓整枝,每667平方公尺種植此品種的最佳密度為500株。Bap performed more important function than kt in differentiation of tall fescue embryogenic calli, but better results could be achieved with combination of 2mg / l bap and 0. 5mg / l kt. at this cytokinin level, 0. 5mg / l naa was recommended to obtain the highest callus regeneration frequency. plant regeneration could be evidently boosted when embryogenic calli were pre - differentiated on high - osmoticum medium with 60g / l sucrose, and / or when the pre - differentiated compact calli were differentiated on differentiation medium solidified with l0g / l agar
高羊茅胚性愈傷組織分化時, bap的作用要比kt大,但2mg lbap與0 . 5mg lkt配合可獲得更佳的效果;在該細胞分裂素水平下,生長素naa用0 . 5mg l ,愈傷組織再生率最高;胚性愈傷組織先在含60g l蔗糖的分化培養基上高滲預分化,以及經高滲預分化后的緻密愈傷組織在瓊脂濃度為10g l的分化培養基上分化,能明顯促進愈傷組織的植株再生;在分化培養基中添加脯氨酸導致愈傷組織再生率下降,但同時有減少白化苗再生的趨勢。
