| 摘 要： | 将采集自湛江海区的海马齿(Sesuvium portulacastrum)人工培植于天然海水、室外对虾集约化养殖池水、室内对虾工厂化养殖池水中(培植过程中除培植水源不同之外其余培植条件均保持一致),研究不同培植水源对其根、茎生长的影响。结果表明:不同培植水源对海马齿根、茎的生长具有显著性的影响(P<0.05),其中海马齿根的生长速率为:室外对虾集约化养殖池水>室内对虾工厂化养殖池水>天然海水,茎的则为天然海水>室外对虾集约化养殖池水>室内对虾工厂化养殖池水;在相同的生长时间内海马齿根的生长明显优于茎的生长;以三次函数的形式表达海马齿根、茎的前期生长情况较为符合。

| Abstract: | Sesuvium portulacastrum collected from Zhanjiang gulf were cultured in three kind of water source such as marine water from coast of Donghai island(group C),from outdoor intensive cultured shrimp ponds(group A),and from indoor industrial cultured shrimp ponds(group B).The effects of cultured water source on Sesuvium portulacastrum growth were studied.As the results showed that: the regressive equation of the growth of root and caudex of Sesuvium portulacastrum both were cubic equation;the growths of root were better than that of caudex in the same growth phase;the growths of Sesuvium portulacastrum cultured in three kind of water source were significantly different(P<0.05),as far as the growth rate of caudex were concerned,which value of group C was the highest and that of the group A was lower than group B,but the highest value of root was from group A,and that of the group C was lower than group B. |
