播种期对芝麻生育期及产量性状的影响
Effects of Different Sowing Dates on Growth Duration and Yield Characteristics of Sesame
摘要
Abstract
In order to provide scientific reference for application of sesame, a field experiment with ten sowing dates from April 30 to July 29 was conducted to study the effect of different sowing dates on growth duration and yield characteristics of sesame.The results indicated that the sowing dates had significant influence on sesame growth duration, which showed a increase-decrease-slight increase trend.The plant height (PH), first capsule height (FCH) and yield per plant (YPP) of sesame showed increase-decrease trend, and YPP was highest in treatment of May 21.Capsule nodes per plant (CNP),seeds per capsule (SPC) and thousand-seed weight (TSW) were decreased, while length and width of capsule changed unconspicuously.And so did the ineffective top part, only biggest on the 6th (sowed at June 9) and 7th (sowed at June 19) sowing time.Difference in yield among different treatments was significant at 0.01 or 0.05 level.Therefore, the sowing dates had significant influence on sesame growth duration and yield characteristics, and the appropriate sowing dates of sesame were from May 1st to July 20th, and the highest yield cloud been got in late May treatment.关键词
