“…Temperature and plant phytochromes are factors that can play an effective role in seed dormancy. Unlike the results of this experiment, the low germination percentages reported by Sekhukhune et al [13] were because of seed sowing immediately after receiving stratification treatment and no light treatment.…”

“…The difference between kiwifruit genotypes (DA, CK, AA and Hybrid) for germination characteristics was mostly due to differences in the chilling requirement period. Sekhukhune et al [13] reported that 37 days of stratification at 4 • C for CK seeds in in vitro culture induced 16% germination but had no effect on germination of AA genotypes. Zhao et al [19] also found that the reason for differences between kiwifruit genotypes in terms of seed germination could be due to differences in their ploidy.…”

“…Prolonged germination time is an indicator of seed dormancy that can be alleviated by using different mechanisms before seed planting. In general, when seeds break dormancy, the germination rate increases owing to the elimination of dormancy agents, and there can be a high correlation between the duration of stratification treatment and seed germination rate [13].…”

“…Although some studies showed that gibberellic acid can enhance kiwifruit seed germination [4,11,12], other studies indicated that cold moist stratification is more effective than gibberellic acid in breaking kiwifruit seed dormancy [8,9,13]. They also found that vermiculite is not a suitable medium for seed germination.…”

The presence of dormant embryos in seeds and nonuniformity in seedling growth are the main limiting factors for kiwifruit propagation. Studies on the germination of hybrid genotypes are limited, especially at different ploidy levels. Low germination percentages and nonuniformity in seedling growth are two of the limiting factors of kiwifruit breeding, especially new and imported germplasm. The effect of cold moist stratification and growing substances on seed germination and seedling growth, respectively, on different kiwifruit seed populations were evaluated in this study. The effect of cold moist stratification (3, 4 and 5 weeks at 4 °C) and growing substrate composition (peat, perlite and coco peat) on seed germination and seedling growth of different Actinidia genotypes were assessed. In general, increasing stratification period duration often increased germination speed and uniformity. It was also found that increasing the ratio of peat moss improved the vegetative growth parameters of all kiwifruit seedlings. Stratification treatment, light and temperature fluctuation and consequently suitable substrate can accelerate and increase the production of seedlings and reduce seedling losses. It was also found that peat–perlite (1:1) medium was the best medium for kiwifruit seedling growth.

In Bhutan, cultivation of exotic commercial Kiwifruit fruit is new though wild kiwifruit is found aplenty. There is a high scope for kiwifruit cultivation as it is suitable in a wide range of areas in the country. It can also be grown organically due to the lack of any known serious pest or disease. Fittingly, kiwifruit is counted among the most potential high-value fruit crops in the country. Its cultivation is gaining popularity in the current times and it would consequently increase the demand for kiwifruit seedlings. Kiwifruit seeds exhibit physiological seed dormancy which hampers kiwifruit seedling production. Hence, a study was conducted in 2019 and 2020 at ARDC, Wengkhar. In the study, the combined effect of GA3 and growth medium on kiwifruit seed germination was studied using eight treatments with three replications laid out in a Completely Randomized Design. The study aimed to find out the germination parameters like germination percentage, relativized percentage, mean germination time, time taken for 10% germination, and time taken for 25% germination. According to the study, Cocopeat + 1500 ppm GA3 gave the best germination percentage at 51% followed by Biochar + 1500 PPM at 39% while rice bran and compost exhibited a low germination percentage. Overall, the mean germination time was found to be 50 days. The highest relativized percentage of 63 % was observed in Cocopeat + 1500 ppm GA3. As for the time taken to achieve 10% and 20% germination, those treatments with 1500 GA3 application had an advantage of approximately eight days over the others. Overall, considering the average weighted effect of germination percentage and time, Cocopeat + GA3 1500 PPM gave the best result followed by Biochar + GA3 1500 PPM and Cocopeat + GA3 0 PPM. Hence, the study indicates that GA3 treatment in combination with an appropriate germination medium can significantly enhance seed germination in kiwifruit.
