Physico-chemical characteristics of some promising peach cultivars grown under humid temperate mid hills of Uttaranchal.

Comparative Response of Some Peach [Prunus persica (L.) Batsch.] Accessions for Tree, Foliage and Floral Traits

“…No definite relationship however, could be established among the staining tests (acetocarmine and erythrosin B) and the pollen germination test. Similar results were observed in different sets of varieties by Josan and Chohan (1980), Kumar et al (2004), Tandon (2006), Fakim et al (2011), Yepthomi (2011) and Joshi et al (2017). The variation in pollen germination percentage so observed may be attributed to the genotypic constitution of the pollen in different accessions.…”

Genetic divergence in khirni (Manilkara hexandra) under semi- arid ecosystem of western India

“…Maximum pollen viability (94.86%) was observed in CHESK-10, which was closely followed by CHESK-2 and CHESK-5, however minimum pollen viability was observed in CHESK-4 (84.23%). Kumar et al (2004) reported that pollen viability ranged from 74.90-94.22% in different peach cultivars under Uttaranchal conditions. Singh et al (2004) obtained 75.60-88.00% pollen viability in different pear cultivars.…”

Studies on Floral Morphology of Subtropical Plum (Prunus salicina Lindl.)

“…Similar reports have been reported by Sandhu (2002) and Bal and Nandan (2013) in plum varieties in 15 and 20 per cent sucrose solution, whereas Shaoling ( 2003) reported 60 to 90 per cent pollen germination rate in 10 per cent sucrose solution. Sharma and Bist (2003) observed maximum germination of pollen grains in 15 per cent sucrose solution + 10 ppm boric acid, whereas Kumar et al, (2004) recorded the high pollen germinabitily in 10 and 15 per cent sucrose solution in July Elberta peach.…”

“…The results of the investigations are in conformity with the results obtained by Gercekcioglu et al, (2000) who reported that pollen viability ranged from 71.53-81.78 per cent in stone fruit cultivars (plum) and Sharma and Bist (2003) who observed pollen viability range from 77.08 to 93.05 per cent in different varieties under Himachal Pradesh (India) conditions. Kumar et al, (2004) studied the lowest pollen viability in Crawford Early 74.90 per cent and 94.22 per cent highest viability in Early White Giant peach. Further, found highest pollen germination (61.2 per cent) in 20 per cent sucrose solution followed by 58.9 per cent to 56.6 per cent in 15 per cent and 10 per cent sucrose solution (Table 5).…”

“…Wells and Bukovac (2000) observed flower initiation and differentiation in plum cultivar 'Stanley' and reported that all buds examined between 30 and 50 days after full bloom (DAFB) had conical apices and were considered vegetative. Kumar et al, (2004) reported that the peach cultivars differed in their requirement to complete the bud development and the period varied from 22 days in Early white Giant to 26 days in Crawford. Plum flowers were bracteates, pedicilate, complete, regular and hermaphrodite.…”
