Answer:
The effects on pigment composition and photosynthesis of low temperature during growth were examined in the third leaf of three chilling-tolerant and three chilling-sensitive genotypes of Zea mays L. The plants were grown under a controlled environment at 24 or 14 °C at a photon flux density (PFD) of 200 or 600 μmol m–2 s–1. At 24 °C, the two classes of genotypes showed little differences in their photosynthetic activity and their composition of pigments. At 14 °C, photosynthetic activity was considerably reduced but the chilling-tolerant genotypes displayed higher photosynthetic rates than the chilling-sensitive ones. Plants grown at 14 °C showed a reduced chlorophyll (Chl) a + b content and a reduced Chl a/b ratio but an increased ratio of total carotenoids to Chl a + b. These changes in pigment composition in plants grown at low temperature were generally more pronounced in the chilling-sensitive genotypes than in the tolerant ones, particularly at high PFD. Furthermore, at 14 °C, all the genotypes showed increased ratios of lutein, neoxanthin and xanthophyll-cycle carotenoids to Chl a + b but a reduced ratio of β-carotene to Chl a + b, especially at high PFD. At 14 °C, the chilling-tolerant genotypes, when compared with the sensitive ones, were characterized by higher contents of β-carotene and neoxanthin, a lower content of xanthophyll-cycle carotenoids, a lower ratio of xanthophylls to β-carotene, and less of their xanthophyll-cycle carotenoid pool in the form of zeaxanthin. These differences between the two classes of genotypes were more pronounced at high PFD than at low PFD. The results are discussed in terms of the relationship that may exist in maize between pigment composition and the capacity to form an efficient photosynthetic apparatus at low growth temperature.

the measures to raise positive attitudes towards the Cooperatives of Nepal. in 4 points
Answer:
The government of Nepal has embraced cooperatives as one of the three pillars of the economy, cognizant of their power and evolving prospects to contribute to poverty reduction, service delivery, gender equality and good governance.
Across the world today, cooperatives are increasingly seen as key players at the grassroots level, effectively organizing farmers and small businesses, providing much-needed financial support, and empowering the poor by creating jobs and income-generating activities. It is therefore not surprising that the government of Nepal has embraced cooperatives as one of the three main pillars of the economy, alongside the public and private sectors.
Cooperatives are present across diverse sectors including agricultural, financial and savings, consumer, multipurpose, electricity and health, among others.
Nepal has a long tradition of informal community-based groups engaged in savings and credit, grain savings and labour exchanges. Since their formalization in the mid 1950s, cooperatives have grown significantly, are found in diverse sectors and play an important part in the development of the Nepalese economy by integrating people from different ethnic, social and marginalized backgrounds. In the current times, the cooperative movement is focused on poverty alleviation while promoting women’s participation in cooperatives in membership and leadership roles.
