Analysis of net assimilation rate and crop growth rate indicates that two peaks of photosynthetic activity occur during the growing season . 凈同化率和作物生長(zhǎng)率分析表明,在生長(zhǎng)季節(jié)出現(xiàn)兩個(gè)光合活性高峰。
Specific leaf weight and nitrogen content had positive relation to the net assimilation rate 比葉重和含氮量與凈同化速率間存在正相關(guān)。
Chlorophyll content had no significant relation with the net assimilation rate , but was related to the nitrogen content and the specific leaf weight 葉綠素含量與凈同化速率間沒有顯著關(guān)系,但與含氮量和比葉重有關(guān)。
The biometric results demonstrated that there were significant differences among testing varieties in net assimilation rate and net photosynthetic rate 生物統(tǒng)計(jì)結(jié)果表明,供試品種間凈同化速率和凈光合速率存在顯著差異。
