nuda_ new shoots can be found from April to May, and the species is distributed in Shaanxi, Jiangsu, Anhui, Zhejiang, Fujian, China and Hunan, and Taiwan [50]. The shooting period of _P. nuda_ was also studied in Lian, China with an annual average temperature of that region being 16.5 \({}^{\circ}\)C during the studied period [42]. The shooting period of this species was from the 31 st of March to the 18 th of April in 2014 and the 31 st of March to the 19 th of April in 2015. The new shoots of _P. parvifolia_ grow in early May, and are distributed in Zhejiang and Anhui, in China [50]. _P. parvifolia_ f. _notata_ was observed to have its shooting time from the last week of April to last week of May at the banks of the middle and lower reaches of the Yongbu River, China from 1986 to 1989, with a recorded average annual temperature of 18-19 \({}^{\circ}\)C [58]. _P. prominens_ grows its new shoots in May and is native to Zhejiang province in China [50]. The shooting period of _P. prominens_ was studied in Lian, China, with 16.5 \({}^{\circ}\)C being the annual average temperature of the region [42]. The shooting period of this species was between the 9 th and 24 th April in 2014 and between the 12 th and 27 th April in 2015. The shooting time of this species was only during half of the month, 15 days for both studied years. _P. propinqua_ new shoots develop during April to May in China, and are distributed in Henan, Jiangsu, Anhui, Zhejiang, Hubei, Guizhou, and Guangxi. It was introduced to the USA [50]. April to May was the shooting period of _P. propinqua_ in the Beijing Area, and the shoot growing period was accomplished within 45-50 days after emergence, where the annual average temperature was recorded to be 11.8 \({}^{\circ}\)C [73]. _P. sulphurea_ shoots emerge in the middle of May, and the species grows along the Yellow River and Changjiang River, Fujian, in China [50]. The shooting period of _P. sulphurea_ was studied in Lian, China, with the annual average temperature of the region recorded to be 16.5 \({}^{\circ}\)C [42]. The shooting period of this species was from the 6 th of May to the 1 st of June in 2014 and from the 8 th of May to the 31 st of May in 2015 [11, 45]. The new shoots of _P. viridglaucscens_ grow in late April. The species is distributed in Jiangsu, Zhejiang, Anhui, Jiangxi in China, and was introduced to France [50, 74]. _P. viridglaucscens_ new culm shoots emerged at the end of April, and the culm sheaths fell from the middle of May to the end of June in Rome, in 2005 [17]. It also developed new leaves at the end of June, and it reached maximum expansion in the middle of July, while 65% of old leaves fell in May. At the observation site, the mean minimum air temperature of the coldest month (February) was 5.6 \({}^{\circ}\)C, and the mean maximum air temperature of the hottest months (July-August) was 31 \({}^{\circ}\)C. The dry period lasted from May to August, and the mean maximum air temperature was 29 \({}^{\circ}\)C.  
_P. violascens_ develops new shoots in May. It is native to Jiangsu, Anhui, Zhejiang, Jiangxi, Hunan, Fujian and was introduced to Chongquing and Sichuan in China [50], while another source [74] determined the shooting period to be from March to April. This species is early in shooting and has high yields of new shoots for which it is widely grown in China. The shooting period of _P. violascens_ was studied in Lian, China with an annual average temperature of 16.5 \({}^{\circ}\)C in that region. The shooting period of this specie was from the 4 th of March to the 6 th of April (34 days total) in 2014 and from the 8 th of March to the 9 th of April (33 days total) in 2015 [42]. The _P. praccox_ f. _notata_ (_P. violescens_ f. _notata_) shooting time was observed to be from the 1 st of March to the 30 th of April at the banks of the middle and lower reaches of the Yongbu River from 1986 to 1989 with a recorded annual average temperature of 18-19 \({}^{\circ}\)C at the observation site [58]. The shooting period of _P. praccox_ (_P.
