GA3处理和不同栽培基质对彩色马蹄莲生长的影响

研究了不同浓度赤霉素(GA3)喷洒对7种彩色马蹄莲种球出芽及不同栽培基质对其生长的影响。结果表明:7种彩色马蹄莲种球经0～1200mg·L-1GA3喷洒后,其出芽率随处理浓度的增大呈先升后降趋势,各品种于1000mg·L-1GA3处理下达最高出芽率,且显著高于对照(P<0.05);三种基质配比试验中,7种彩色马蹄莲株高、球茎重量、开花期、花梗长度及佛焰苞口径等几个指标均在基质2中的表现相对好于基质1和基质3;09和16号品种适宜盆栽,08、21、33、37、47号品种适宜切花或盆栽。

Influences of different gibberellin and media on growth of seven cultivars of colour callalily

Gibberellin accelerating germination to 7 cultivars of colour callalily and different media on its growth were researched in the paper.It was shown that the germination of 7 cultivars of colour callalily appeared to increase initially and then reach their peaks at 1 000 mg·L-1 and tended to decline later on with GA3 treatments,and it was higher significantly that the germination of 7 cultivars of colour callalily by 1 000 mg·L-1 GA3 than that of CK(P<0.05).In the 3 media,it was better that the height,bulbs weight,flowering stage,length of flower stems and spathe diameter of 7 cultivars of colour callalily which grew in the medium 2 than those grew in other 2 media.08,21,33,37 and 47 can be cultivated in pots and cuting flowings,but 09 and 16 only can be cultivated in pots.
