Abstract

Poor seed germination, which is due to various germination inhibitors, is a matter of concern in papaya. The presence of a sarcotesta plays a leading role in causing hindrances in this regard. Hence, the purpose of this study was to examine the combined effects of seed stratification at 7–8 0C and seedling administration with cycocel with regard to papaya germination, growth, and development. Vermicompost, coco peat, and garden soil were combined to create the potting media. A total of 11 treatments made up the experiment, which combined varying stratification times (measured in days) with multiple cycocel concentrations (measured in ppm) in the seedlings that germinated. The experiment was designed using the completely randomized design (CRD) statistical method, with three replications of each treatment. Several characteristics of the papaya seedlings were noted and examined during their developmental stage. In terms of germination percentage, the entire study indicated that seed stratification for 20 days and then cycocel application at 100 and 200 ppm were the most promising with a value of 86.67% in each case. After 10 days of seed stratification and 800 ppm of cycocel application, the overall quantity of leaves was noticeably higher (9.00 leaves). For the same 10-day stratification period, the maximum leaf length measured was 6.67 cm; however, 200 ppm of cycocel was applied. Following a 10- and 20-day stratification process, the application of 300 ppm of cycocel resulted in higher end values for the number of roots (34.67 for both combinations); however, the treatments had no effect on root length, as the control group recorded the highest mean value (9.27 cm). Lastly, the maximum accumulation of chlorophyll was demonstrated by a 20-day stratification period and a 600-ppm cycocel application (0.360 mg g−1). Thus, based on the study, we can conclude that the employment of cycocel and stratification have proven to be beneficial techniques for papaya seed development. Promising outcomes were seen with both the stratification times of 10 and 20 days in addition to varying cycocel concentrations.

种子低温分层和幼苗施用环孢菌素对木瓜属性的影响
木瓜种子发芽率低是一个令人担忧的问题,这是各种发芽抑制剂造成的。在这方面,石硫合剂的存在起着主要的阻碍作用。因此,本研究的目的是考察在 7-8 0C 温度条件下对种子进行层积处理以及在幼苗期施用苏铁对木瓜发芽、生长和发育的综合影响。蛭石、椰子泥炭和园土混合制成盆栽介质。实验共有 11 个处理,结合了不同的分层时间(以天为单位)和发芽秧苗中的多种苏铁浓度(以 ppm 为单位)。实验采用完全随机设计(CRD)统计方法,每个处理有三个重复。在木瓜幼苗的生长发育阶段,对其若干特征进行了记录和检测。就发芽率而言,整个研究表明,种子经过 20 天的层积处理,然后施用浓度为 100 和 200 ppm 的霜霉威,发芽率最高,均为 86.67%。经过 10 天的种子层积和施用 800 ppm 的霜霉威后,叶片的总体数量明显增加(9.00 片)。在同样的 10 天分层期,测得的最大叶长为 6.67 厘米;但施用的是 200 ppm 的赛克赛尔。在 10 天和 20 天的分层过程中,施用 300 ppm 的苏合香可使根的数量达到更高的终值(两种组合均为 34.67);但是,处理方法对根的长度没有影响,因为对照组记录的平均值最高(9.27 厘米)。最后,20 天的分层期和施用 600ppm 的苏合香(0.360 mg g-1)显示了叶绿素的最大积累。因此,根据这项研究,我们可以得出结论:事实证明,使用苏铁和层积对木瓜种子的生长发育是有益的。除了使用不同浓度的木瓜环糊精外,10 天和 20 天的层积时间也能产生良好的效果。
