A field trial was made during November to March 2010-2011 and 2011-2012 at Central Research Farm, Gayeshpur, B.C.K.V. farm, Nadia, West Bengal to study the floral biology of two species Cucurbita moschata and C. pepo. One genotype each of both the species was chosen as the materials for the study.
The study revealed that both species showed monoecious sex form. Using statistical analysis of mean and standard error it was found that it took lesser number of days for visible flower bud to opening of both male and female flower in C. moschata compared to C. pepo flower from the visible bud stage irrespective of the species. It was found that pollen germinability is higher in C. moschata than C. pepo. In both Cucurbita pepo and C. moschata stigma …show more content…

In Cucurbita pepo mean pollen viability was 88.23 ± 5.86% in 1st year and 73.48 ± 7.58% in second year. In Cucurbita moschata mean pollen viability was 75.19 ± 6.82% in first year and 82.86 ± 8.16% in the 2nd year. It can be suggested to use high pollen mass at the time of hand pollination to get appreciable fruit set in both the species. In vitro pollen germinability: In vitro pollen germination (Table 3) of both Cucurbita sp. was in general low particularly in Cucurbita pepo. In Cucurbita pepo mean pollen germination was 26.55 ± 4.82% in the 1st year and 19.56 ± 5.26% in 2nd year. In Cucurbita moschata mean pollen germination 35.61 ± 6.32% in the 1st year and in the 2nd year 29.56 ± 7.96% Vasit (1960), Subramanyam et al. (1972) and Mathur and Nath (1978) reported about 40% in different cucurbits such as ash gourd, sponge gourd, bitter gourd, bottle gourd, maskmelon and ridge gourd in the germinating liquid containing 20% sucrose which agreed well to the present findings in two Cucurbita

    This experiment was conducted to determine whether or not Callosobruchus maculatus, or bean beetles, had a bean color preference for oviposition choice. Oviposition is the process of a female insect laying her eyes on plant parts and other materials, which can be influenced by many factors. The bean beetle eggs are opaque and clear, which allowed us to test the hypothesis that C. maculatus prefer the darker red Adzuki beans over the white Black-eyed peas for oviposition choice. Two different colored bean types were used, the red Adzuki beans and the white Black-eyed peas. We placed three female and two male bean beetles in each petri dish, with 55 of each bean type randomly placed in the dish, for a week.

    It is a short-day plant and tends to flower and bear fruit earlier in spring than most native species and this allows it to grow better with little to no competition (Huebner et al., 2006; Axtell et al., 2010; Kertabad et al., 2013). When lesser celandine grows, it tends to form in patches of green marsh that inhibit the growth of native plant species and shortly after these green marshes form it drops green sepals exposing bright yellow flowers (Axtell et al., 2010; Kertabad et al., 2013). The flowering process of lesser celandine is controlled by a few indication variables such as; water availability, light reception, and temperature (Axtell et al., 2010). It is an unusual plant when it comes to reproduction as it is a dicotyledon, but it only produces monocotyledon seedlings (Kertabad et al., 2013). Lesser celandine may use aerial bulblets for reproduction, but it primarily reproduces through subterranean bulblets or tubers (Axtell et al.
