六月红早熟芋脱毒组培株系试种初报

Preliminary report of trial experiment on virus-free and tissue-culture lines of early-maturing taro "Liuyuehong"

六月红早熟芋脱毒组培S1、S2株系具有熟期提早、叶片数减少、单株结子芋个数较多等特点,S1株系子芋膨大日数为30 d,比S2株系少10 d,但其生物与经济产量的消长与六月红早熟芋差别不大,符合子芋膨大后自然消减规律。

Tissue-culture and virus-free seedling lines S1 and S2 of early-maturing taro ＂Liuyuehong＂ had good characteristics of earlier maturity, less leaves and more cormels per plant. The cormel expansion days of S1 line were 30d and were 10d less than that of S2 line. The growth dynamics of leaves and root system of S1 line had no significant difference from the initial cul- tivar of early-maturing tam ＂Liuyuehong＂ and was in accordance with the natural dynamics after cormel expansion.
