Abstract

The present investigation was carried out at Floriculture Research Farm, ACHF, NAU, Navsari during August-November, 2019 in CRD with factorial concept with three replications comprising two varieties and twelve different seed priming treatments. The findings revealed that significantly maximum speed of germination (24.45), germination percentage at 7th and 14th day (71.50 and 90.00, respectively), root length (6.63 cm), seedling length (17.70 cm), seedling fresh and dry weight (1618.00 mg and 141.33 mg, respectively), seed vigour index-I and II (1627.62 and 10082.00, respectively) was recorded in seeds of var Arka Archana primed with GA3 @ 100 ppm for 24 hrs (V1T5) followed by GA3 50 ppm for 24 hrs. Whereas, rest of all the characters were found non-significant but maximum shoot length (11.07 cm), minimum mean germination time (13.67 days) and days required to reach the 5th leaf stage (29.60) were obtained in same treatment (V1T5). Moreover, poor performance was recorded in seeds of var Arka Kamini treated with Nauroji Novel organic liquid fertilizer @ 2 % for 24 hrs (V2T12).

灌种对紫菀萌发及萌发初期生长的影响需要雇。)品种

本研究于2019年8 - 11月在花卉研究农场，ACHF, NAU, Navsari进行了CRD，采用析因概念，三个重复，包括两个品种和12种不同的种子引种处理。结果表明，在GA3 @ 100 ppm (V1T5)、GA3 @ 50 ppm (V1T5)和GA3 @ 50 ppm (V1T5)处理24 h后，Arka Archana种子的最大萌发速度(24.45)、第7和第14天的发芽率(分别为71.50和90.00)、根长(6.63 cm)、苗长(17.70 cm)、幼苗鲜重和干重(分别为1618.00和141.33 mg)、种子活力指数i和II(分别为1627.62和10082.00)显著高于其他处理。其余性状均不显著，但同一处理(V1T5)的茎长最大(11.07 cm)，平均发芽时间最短(13.67 d)，达到第5叶期所需天数最短(29.60 d)。此外，用@ 2%的诺罗吉新型有机液肥(V2T12)处理24小时后，Arka Kamini品种的种子表现不佳。
